XLR Type Audio ConnectorThe connectors are wired as follows.The pin 1 is ground (shield), the pin 2 cold (low, minus), the pin 3 hot(high,plus).2. Description of components and functions on the MX-101.Various descriptions are applied, depending on each manufacturer. In ourOperating and Instruction Manual explanation of components and func-tions is made according to our usage for them.General DescriptionThe TOA MX-101 is a very compact, four channel self-powered mixer. It wasdesigned to deliver maximum features and performance in a cost-effective portable PA package.The MX-101 features four input channels, one main system output, and onepersonal monitoring (foldback) output. The internal amplifier is rated at 57 wattsRMS into an 8 ohm load, and 75 watts into 4 ohms.Each input channel has an electronically balanced XLR connector, and ahigh-impedance unbalanced 1/4" phone jack. In addition, each channel features an EQ control and a post-EQ reverb level control (send).The master control section features a 3-band equalizer, a high-quality 2 springreverb, RCA tape inputs, and master volume controls for System level, Foldback,and Reverb return to both.The power amp features protection circuitry and autocomp compressor, both with indicator LED's.Features1. Four input channels2. 57 watts into 8 ohms, 75 watts into 4 ohms3. 3-band EQ4. Auto Comp compression unit w/LED5. Built-in spring reverb6. Power amp protection circuitry w/LED7. System output jack8. Tape input w/level control, RCA jacks9. Reverb level to System10. Foldback level controlEach Channel1. Input level control2. EQ control3. Post-EQ Reverb send4. Low-Z electronically balanced XLR input5. Hi-Z unbalanced 1/4" inputReverb Control(REV)This control determines the level of signal assigned to the reverb mixing buss. Rotating the control clockwise increase the amount of reverb in that channel.High Equalizer Control(HIGH)The high EQ control alters the high frequency response, pro-viding ±13dB at 5kHz, and ±15dB at 15kHz of continuous-ly variable active shelving equalization. The "0" detented position provides flat audio re-sponse.Middle Equalizer Control(MID)The mid EQ control provided ±15dB of continuously variable active peaking equalization at 2kHz, and has a flat audio re-sponse when set to the "0" detented position.Input Level Control(LEVEL)The level control provides con-tinuously variable adjustment of the channel output to the program mixing buss, thus de-termining the level of that chan-nel in the main sound system mix. Since the reverb signal is "post" this control, an increase in the level of the channel's output will also result in a corresponding increase in the reverb effect of that channel. The nominal level of the input level control is at the "10" posi-tion.Tape Level Control(TAPE)This control sets the overalllevel of the Tape input signal.Reverb Control(REV)This control adjusts the amountof reverb signal that is returnedto the program buss and thusthe level of reverb contained inthe main sound system.Foldback Master Control (FB)The FB master control adjuststhe overall combined signallevel of the four independentchannel level controls, and thusthe level of the entire on-stagemonitor mix.System Level Control(SYSTEM LEVEL)The System level (PGM) controladjusts the overall combinedsignal level of the four indepen-dent channel level controls, andthus the level of the main soundsystem.Low Equalizer Control(LOW)The low EQ control provides±13dB at 100Hz, and ±15dB at50Hz of continuously variableactive shelving equalization.The "0" detented position pro-vides flat audio response.EQ C ontrol(EQ)Rotating the control clockwise decreases the low frequency signal, and rotating the control counter clockwise decreases the high frequency signal. The center position provides flat au-dio response.Tape Input Jacks(TAPE)These RCA pin jacks are wiredin parallel, with an input levelof -10dB.Power I ndicator L ED(POWER)The indicator LED lights whenthe power switch is "on".Power Amp Protection Indica-tor(PROTECT)The indicator LED lights if thepower amplifier output isshorted, if the temperature ofthe unit rises above acceptablelevels, or if DC is drifted to thespeaker output. If the LEDshould light, speaker wiringand ambient temperature of theMX-101 should be checked. Ifthe LED remains lighted, theunit should be referred to qual-ified service personnel for re-pair.High Impedance Connectors (HIGH Z)These connectors are unba-lanced, standard 1/4" phone jacks with an input impedance of 100k ohms, and an input level of -35dB. When a plug is inserted into the high-Z input, the coresponding XLR connec-tor is automatically switched out of the input circuitry.Power Amp Compression In- dicator(COMP)The comp LED lights when the internal compressor is acti-vated. The compressor is pro-vided to protect speaker sys-tems by compressing the input signal level of the power ampli-fier when clipping occurs in the output stage. Frequent flashing of the LED is not reason for alarm. However a constant or steady light indicates that the MX-101 is being over-driven and that the internal power amplifier is possibly "under po-wered" for that application. The output level of the MX-101 should be decreased until the LED only flashes intermittently.Low Impedance Connectors(LOW Z)The XLR connectors are low impedance, electronically ba-lanced inputs with an input impedance of 1k ohms.Note:The MX-101 protection circuit-ry will (1) detect 'faulty condi-tions' within the power ampli-fier, (2) give a visual indication, and (3) automatically shut down until the fault condition is alleviated. This special cir-cuitry ensures maximum re-liability and virtually elimin-ates equipment damage due to unsafe or fault conditions. Please refer to fault protection table on page 4 for full explana-tion of this important feature.Speaker Jacks(SPEAKERS) The speaker outputs are stan-dard 1/4" phone jacks wired in parallel. Speaker cables (recom-mend at least #18 gauge wire) should be connected between the MX-101 and the speaker systems prior to applying pow-er to the unit.System Output Jack (SYSTEM OUT)The System Out jack is pro-vided for connection to external equalizers and / or power amps. Nominal output level is +4dB with an impedance of 600 ohms.Caution- The MX-101 should never be operated into less than a 4 ohms speaker load.Foldback Output Jack(FB OUT)This jack is for connection to external power amplifiers and / or equalizers for the on-stage monitoring system. Nominal output level is +4dB with an impedance of 600 ohm. Caution:To insure maximum cooling of the MX-101, adequate clearance should be maintained between the rear panel and any other surface (4-6 inches should do). The vents on the bottom and top of the MX-101 are also provided for convection cool-ing. These vents should be kept clear and open. Failure to do so may cause thermal shut-down of the unit.Power Switch(POWER)The power switch is a three-position type with the middle position being the "off" posi-tion. The MX-101 should beoperated in the switch position which produces the lowest amount of system hum.AC Power CordThe power cord is the three-wire type with proper ground-ing facilities.Earth Terminal (GND)AC FuseCaution- The ground pinshould not be removed underany circumstances. If the MX-101 must be used without prop-er grounding facilities, a suit-able grounding adapter shouldbe utilized.Operation of the MX-101 withproper grounding techniqueswill result in less system noiseand greatly reduced shockhazard.WarningTo avoid possible equipmentdamage and / or personnel in-jury, the fuse should always bereplaced with same type andrating. Using improper fuseswill also void the warranty. TheMX-101 should always be dis-connected from AC outlet priorto changing fuses. If fuses repe-atedly fails, the unit should bereferred to qualified service per-sonnel for repair.Fault Protection TableFaultExcessive current due to overloads.Short circuits(less than 0.4-ohm) Temperature rise of heat sink(more than 105°C)DC drift ProtectionCurrent limiter activatesat less than 2 ohm.Current limiter activatesinput signal is lowered,unit shuts down.Input signal is lowered.Unit shuts downInput signal is lowered.Unit shuts downIndicationCompressorLED illuminatesAmp protectionLED illuminates.Amp protectionLED illuminates.Amp protectionLED illuminates.ActionRemove excessive loadsMinimum speaker loads4 ohm.Check speakerlines/systems for shorts.Check for adequateventilation.Refer to qualified servicepersonnelRestorationAutomatic restorationafter normal loads areobtained.Turn off power switch.Turn on into operationalloads.Automatic restorationafter temperaturelowers (to 75° -95° C)Automatic restorationafter normal bias isregainedConnection ExamplesSPEAKER SYSTEM(Self powered speakers)for foldbackMAIN SPEAKER SYSTEMFrom FB OUT Jack on Rear Panel From Speaker Jack on Real PanelLow Z input should be connectedwith low impedance (50 ohm ~ 600 ohm) microphonesLine OutKEYBOARDCASSETTE TAPE DECKfor playbackLine OutMUSICAL INSTRUMENTInput C onnectionsGenerally speaking, there are two rules to follow when connecting equipment outputs to the inputs of other equipment.1. Properly match the impedances of the outputs and inputs.2. Connect low impedance outputs to high impedance inputs.It goes without saying that not only input and output impedance matching, but also level matching should be taken into consideration. Each input channel of the MX-101 is provided with an Input Level Control that includes a negative feedback (NF) circuitry, so the usable signal level range is wide.

The PDB4 is a four channel passive direct box that features four quality fully transformer isolated direct boxes in a 1U19-inch rack mount chassis.Inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps to eliminate system ground loops.It is a rock solid, roadworthy interface for connecting outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles and other balanced audio products.The PDB4 also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.Features•Four Fully Isolated Channels•Switchable Input Attenuation (0dB, -20dB, -40dB)•50k Ohm Phone Instrument/Line input•50k Ohm Phone Parallel Link/Thru Jack•600 Ohm XLR Output Jack•Switchable Ground Lift•1U 19-inch Chassis•Three year warrantyUSING A PDB41. Electric guitar and bass pick up output signalsThe high impedance signal from a guitar or bass guitar pickup is translated by thePDB4 into a low impedance balanced signal required by mixing consoles.Suggested setting – set the input attenuation to 0dB.2. Keyboards and line level signalsThe PDB4 automatically balances and matches the line level outputs of modernelectronic keyboards. If you are using a multiple keyboard setup and your keyboardsare all plugged into a single instrument amplifier, the PDB4 can be used to replaceindividual direct boxes. Simply send the output of the instrument amplifier to the PDB4 and then to the console (instead of a separate DI box for each keyboard).Suggested setting – set the input attenuation to -20dB (line level) or –40dB (amplevel).3. DJ console output signalsDJ mixers often supply only an unbalanced –10dB signal. The PDB4 converts thissignal to a balanced line level signal before it reaches the console, while providing aconvenient method of connector transition with the capability to run long cables.Suggested setting – set the input attenuation to 0dB or –20dB.4. Speaker level signalsThe PDB4’s ability to accept speaker level inputs from a power amplifier’s output allows post-amplifier, post EQ and effects signals to be fed directly to the console. In thismanner, a particular effect or amplifier sound can be sent directly to the mix.Suggested setting – set the input attenuation to –40dB (amp level).However you decide to use it, we're sure you'll find the ART PDB4 Four Channel Passive Direct Box to be an indispensable addition to your audio equipment arsenal.Diagram of One ChannelWARRANTY INFORMATIONLimited WarrantyApplied Research and Technology will provide warranty and service for this unit in accordance with the following warrants:Applied Research and Technology, (ART) warrants to the original purchaser that this product and the components thereof will be free from defects in workmanship and materials for a period of three years from the date of purchase.

Mic Level ControlsEach of the four XLR inputs has a level control knob with a separate red <Peak> LED to indicate clipping on each channel. If you see more than an occasional flash of the <Peak> LED you should decrease the level for that channel.2. Master Level ControlThe <Master> control knob will set the overall level of the sum of all the mic and line inputs. The LED meter for the master audio level ranges from -30 dB to +3 dB.3. Headphone ControlsEach of the four headphone outputs has a separate level control and source selector so each listener can adjust their audio level independently. Monitor a mix of local mic and line inputs including the cue input or only the return audio from the Cue Input / Wireless Phone Interface without the local mix. 4. Cue ControlThe <Cue> input control adjusts the signal going to the headphones from the 1/4” <Cue Input>. When using the 1/4” Cue Input Wireless Interface, the individual headphone level control adjusts the overall level of your headphones while the <Cue> input control adjusts the level of the person on the other side of the call in all headphones. You should keep in mind that your wireless telephone also has level control. If you are having level problems that cannot be corrected with the controls on the RemoteMix x4, try adjusting the level on the wireless telephone itself.Controls & IndicatorsControls & Indicators 35. 120 Hz Low Cut FilterTurn on the Low Cut / High Pass filter to remove room rumble and mic handling noise.6. LED VU MeterRepresents the signal level of all four channels being sent to the<Master Output> and <Line Output>.7. PowerThis is the main power switch that turns the unit on. Whenever the power is turned on, the red LED above this switch will be lit. The green <AC> LED will be lit whenever a live AC power source is connected, even if the main power switch is off.RemoteMix x4 is powered by two 9 volt alkaline batteries located on the side of the unit. The red <Power> LED on the front of the device will gradually dim as the battery runs down, then extinguish about a half hour before the unit shuts down.These two batteries are in separate drawers and wired in parallel, you can hot swap one battery at a time so you never lose power.It is important to replace both at the same time with identical batteries. If two fresh batteries are not available, it is better to run using only one good battery. Since the battery fixtures are wired in parallel, it does not matter which one gets the single battery.Getting to Know Your RemoteMix x4Controls & Indicators Cont’d4RemoteMix x4™ Field Mixer Getting to Know Your RemoteMix x4786124351.

Cue Input / Wireless Phone InterfaceRemoteMix x4 comes equipped with a <Wireless Phone Interface> built in to the 1/4” <Cue Input>. This 1/4” wireless interface accepts a specially designed 1/4” to 3.5mm cable provided with the unit. This interface works with any wireless phone or notebook that accepts standard third partyheadsets and earpieces. Your product has been supplied with a 1/4” TRS to3.5mm TRRS interface cable. While the majority of current wireless phones use a 4 conductor, 3.5mm TRRS headset jack, some older phones use a2.5mm TRS headset jack. If your phone uses this smaller 2.5mm headset jack, you may contact our support department to request a compatible interface cable.When using the wireless interface, it is important to keep your wireless telephone 12” - 24” away from the RemoteMix x4 and any microphone or headphone cables. This will help prevent unwanted RF noise from entering the unit.7. Headphone JacksHeadphone output is determined by the source selector switch next to the Headphone Controls on the front.8. Power JackRemoteMix x4 is battery powered but we also provide a high quality, regulated AC to DC adapter to power RemoteMix x4 when AC power is available. Simply plug it into the back of RemoteMix x4 and plug the transformer into a wall outlet. This is a switching power supply so you can connect to a 110 or 220 VAC power source. When the power connector is inserted into the jack, the batteries are bypassed. The AC adapter does not charge the batteries. If you lose power during your broadcast, theRemoteMix 4 automatically reverts to battery power so your broadcast will not be interrupted.Make sure you use only the supplied AC power adapter with the RemoteMix x4. Using any other adapter could damage the unit.WARNING! It is strongly recommended that this product be connected to an adequate surge protection device.5Getting to Know Your RemoteMix x4FAQs1) How long will the batteries last in my RemoteMix x4?There are many variables that affect battery life, such as the number ofheadphones. All of our battery life tests included 4 headphones playing musicat average listening levels. These tests use standard alkaline batteries.Lithium batteries can add 3 to 4 times the battery life, at 3 to 4 times the cost.The following number is from lab tests and may not represent your usage:10hours using dynamic microphones.2) Will any cellular telephone work with RemoteMix x4?The wireless interface on the RemoteMix x4 works very well with mostcellular telephones. However, some wireless telephones generate excessiveRF noise which can be heard as a “chattering” or “motor boat” sound.The noise from these particular telephones will be unacceptable for mostbroadcast applications.RemoteMix x4 is supplied with a 1/4” TRS to 3.5mm TRRS interface cable.While the majority of current wireless phones use a 4 conductor, 3.5mmTRRS headset jack, some older phones use a 2.5mm TRS headset jack.If your phone uses this smaller 2.5mm headset jack, you may contact oursupport department to request a compatible interface cable.3) What kind of device can I connect to the Cue Input?Setting the switch for the dual-purpose 1/4” input to Cue Input will provide astandard line level input for connection to another audio device, such as aportable radio. The audio signal will be sent to all of the headphone outputs.This way, your announcers can listen for a cue from their radio station at theend of a station break.4) The cellular interface cable was left behind at our last event.Can I get a replacement at our local audio supply store?This is a custom made cable and is not wired the same as those that maybe available at your local electronics store. Please contact your JK Audiodealer or our Customer Service department and ask for a CN113 replacementcable. The CN113 has a 3.5 mm TRRS headset plug. Most newer phones,especially those that include a mp3 player, have a 3.5mm TRRS headset jackand therefore require the CN113 cable.5) The output from Mics 3 & 4 are very low but the other micsare fine.Check the position of the <Mic/Line> switch near Mics 3 & 4. This input canbe switched to accept a line level signal from a mixer or other equipment.6RemoteMix x4™Field MixerFAQs 6) How can I tell how much battery life is remaining?The red <Power> LED functions as a battery life gauge that will gradually dimas the battery runs down. This red LED will go completely dark about a halfhour before the unit shuts down. Keep in mind that the VU meter, Bluetooth,and clipping LEDs will remain bright until the unit stops functioning.7) Does the AC power supply charge the batteries?No. You may use rechargeable batteries, but you must remove and rechargethe batteries outside of the RemoteMix x4.8) I have lost my power supply for my RemoteMix x4 unit.Ihave a power supply that fits from a different product. Can Iuse this instead?No! Never use a power supply other than the one that was supplied by yourmanufacturer. Power supplies are available in either AC or DC output withmany combinations of voltage and available current. Most consumer powersupplies are not regulated. This could invariably damage your equipment,and also create a great deal of noise. Our products are designed for andtested with their respective power supplies for optimum operation. If youhave lost your power supply, please contact your JK Audio dealer or ourCustomer Service department and ask for a PS009 power supply for yourRemoteMix x4.FAQs78RemoteMix x4™ Field MixerTechnical InformationBlock DiagramX I n X I n X I n X I n 3.e r u tm o u th o n e o n e o n e o n e h o n e /u tTechnical Information Input Impedance / LevelFemale XLR (4) Mics:2k ohms / -25 dBu nomChannels 3 & 4 have a -40 dBu Mic/Line pad switch Line Level: 50k ohms / +20 dBu maxPhantom Power:48 VDC with 6.8k ohm supply resistance 1/8” (3.5mm) Stereo Line:20k ohms / -10 dBm nom Headphone Cue 1/4” Mono:20k ohms / -10 dBu nomOutputBalanced Male XLR:50 ohms / +16 dBu max, 20 Hz - 20 kHz, +/- 1dB, 0.04% THD @ +16 dBu1/8” (3.5mm) Stereo:100 ohms, -10 dBu nomHeadphone 1/4” Stereo:8 ohms / 1/3 watt per channelMisc.Power100-240 VAC, 50-60Hz or Two 9 VDC batteriesSize9.5” x 8” x 3” (24 x 20 x 8 cm)Weight 3.6 lbs (1.6 kg)SpecificationsTechnical Information9Declaration of Conformity FCC RegistrationManufacturer’s Name: Manufacturer’s Address:JK Audio, Inc.1311 E 6th Street Sandwich, Illinois 60548 USADeclares that the product:Product Name: Model Numbers:RemoteMix x4 Field Mixer RemoteMix x4Conforms to the following Product Specifications:Safety: ESD:AS/NZS 60950.1:2003CAN/CSA-C22.2 No. 60950-01-03UL Standard 60950-01 1st editionEN 55024:1998; EN 61000-3-2; EN 61000-3-3Emissions:EN 55022:1998AS/NZS CISPR 22 (2002)FCC Part 15, Subpart BICES-003EN 300 328FCC Part 15.247 FCC ID R47F2M03MLAIC Radio Standards RSS-210 Annex 8The product herewith complies with the requirements of the following Directives and carries the CE marking accordingly:LVD 2006/95/EC (Safety)R&TTE 1999/5/EC (Telecom)EMC 89/336/EEC (EMC)RoHS Directive 2015/863The Technical File containing supporting documentation is maintained at:JK Audio, Inc (Corporate Headquarters)Compliance Manager1311 E 6th StreetSandwich, Illinois 60548 USA815-786-2929 phone815-786-8502 fax10RemoteMix x4™Field MixerFCC Part 15 Compliance FCC RegistrationYour new JK Audio product has been registered with the Federal Communications Commission (FCC).
