APX1500 QUICKSTART GUIDEENGLISH2QUICKSTART GUIDE (ENGLISH)BOX CONTENTSAPX1500 Power cable Quickstart GuideSafety & Warranty Information BookletQUICK SETUP1. Make sure all items listed in the BOX CONTENTS section are included in the box.2. READ SAFETY & WARRANTY INFORMATION BOOKLET BEFORE USING THE PRODUCT.3. Study the connection diagram in this guide.4. Place all devices in an appropriate position for operation.5. Make sure all devices are turned off and all faders and gain knobs are set to "zero."6. Connect all sound sources' outputs to amplifier inputs as indicated in the diagram.7. Connect the amplifier outputs to speakers.8. Plug all devices into an appropriate power source. 9.Switch everything on in the following order: • Sound sources (i.e. microphones, turntables, CD players, etc.) • Mixer • Amplifier • Speakers10.When turning powering down, turn everything off in the following order: • Speakers • Amplifier • Mixer • Sound sourcesCONNECTION DIAGRAMDo NOT ma ke a ny connectionswhen any device is powered on.Note: Please see the SPEAKER CONNECTION section for important setup information.3REAR PANEL DIAGRAM41.COOLING FAN - This fan secures cooling for the amplifier. The airflow is from front to rear. The fan speed is electronically regulated depending on the temperature of the power devices. D o not block these fan grills or mount the amplifier in an enclosed rack, which could cause the amplifier to overheat.2. LOW PASS FILTER – This switch activates the built-in low cut filter. All audio below 30 Hz will be removed from the output signal.3. BALANCED COMBO INPUTS –channel.4.OUTPUT MODE SWITCH – The APX 1500 presents three operating modes: Stereo ModeIn this mode, CH 1 and CH 2 operate independently (as a normalstereo amplifier) The CH 1 input signal will be output from the CH A output connector, and CH 2 input signal will be output from the CH 2 output connector.Parallel Mono ModeIn this mode, CH 1 input signal will be output from theoutput connectors of both channels.Bridged ModeIn this mode, CH 1 input signal will be output from thebridge-mono output connector.5.CHANNEL OUTPUTS – Connect your speakers' inputjacks to these outputs.• For the binding posts, red is the positive signal andblack is the negative signal. Please make sure to respect the speaker polarity when using bindingpost. Turn off the unit before connecting an audio signal to the binding post to avoid any electric shock! • The SPEAKON outputs are specifically designed to connect to high power speakers. The correct polarityis secured automatically. They prevent shock hazard and they lock-in securely.6.POWER IN – Connect the cable to a standard wall outlet. Be sure the supplied voltage matches the required voltage of the amplifier. D o not connect the amplifier to an outlet that does not match the required voltage; doing so could damage the amplifier.FRONT PANEL DIAGRAM1.POWER SWITCH – Turns the amplifier on/off.2.POWER LED – Illuminates when the amplifier is on.3.LED METERS – Indicates the audio signal level. This LED will light up when the signal at the output is at least -20 dB.4.CLIP – The red "Clip" light indicates the signal is distorting or "clipping," which occurs when the volumeexceeds the amplifier's maximum output. This LED will flash when distortion reaches a level of 0.5%.Consistent clipping can damage your amplifier and speakers. If the signal is regularly clipping, reduce thevolume of the amplifier. If it is lit about half the time, the amplifier channel's thermal protection will causethe channel to shut down within a few minutes.5.PROT – The red "Prot" light indicates the output for that channel has turned off to protect your amplifier andspeakers, which can be damaged by excessive volume resulting in clipping. If the meters' red lights areilluminating, decrease the levels of your CHANNEL GAIN knobs.6.CHANNEL GAIN – This knob controls the channel's output signal.7.COOLING VENTS – These vents help to cool the internal parts of the amplifier when in use. D o not blockthese vents, and keep the vents clean at all times.SPEAKER CONNECTIONSHORT CIRCUIT PROTECTIONOutput short circuit protection protects the output devices of the amplifier from short circuits andstressful loads. If your speaker lines short, the amplifier automatically detects this problem anddiscontinues operation for that channel. (If one channel's short circuit protection is activated, the otherchannel will continue to operate normally.) D uring short circuit protection, the "Clip" and "Protect"LEDs will light simultaneously, and all output from that channel will stop.Short Circuit Protection can often be traced back to the signal output line (i.e., the speaker line).Check the line from the output terminal of the amplifier to the speaker. If this line is still good, checkthe internal speaker connections and components. (A short circuit can often be traced to a bad cable or a bad speaker component and is rarely traced to the amplifier itself.)Bare Wire Connections:When connecting your speakers to the amplifier using bare wires, follow these steps:1.Unscrew the red and black caps of the binding posts. (Be sure not to completely remove or unscrew the redand black caps.)2.Strip back the wire insulation 1/2" (13mm).3.Insert the bare wire into the hole exposed under the binding post cap.4.After inserting the wire, screw the binding post cap down on the wire.Spade Connector:When connecting your speakers to the amplifier using spade connectors, follow these steps:1.Unscrew the red and black caps of the binding posts. (Be sure not to completely remove or unscrew the redand black caps.)2.Insert the spade connectors into the binding posts.3.Tighten the caps down on the spade connectors.Banana Connectors:When connecting your speakers to the amplifier using banana connectors, follow these steps:1.Be sure that the red and black caps of the binding posts are tightened completely.2.Insert the banana connectors into the caps of the binding posts. Be sure that the connectors are insertedsecurely.4The APX1500 provides three operating modes: stereo mode, parallel (mono) mode and bridged mode, you can decide each specific operating mode according to your actual application circumstance.In STEREO MODE, channel 1 and channel 2 operate independently (as a conventional stereo amplifier). The channel 1 input signal will be output from the channel 1 output connectors, and the channel 2 input signal will be output from the channel 2 output connectors.OPERATION IN PARALLEL MODEIn this mode, the channel 1 input signal will be output from the output connectors of both channels. The channel 2 input jack is not used; the channel 1 and 2 volumes can be adjusted independently. Use the Parallel Mode when you want to drive two speakers with only one input signal keeping separate control of the volume of the two channels. NOTE: Since you are not using the channel 2 input you can use this socket to "daisy-chain" to another amplifier.5In this mode, the channel 1 input signal will be output from the bridge output connectors. (The 2 binding posts) In this case, use the channel 1 volume control to adjust the volume, keep the volume control of channel 2 turned completely down (counter clockwise). Bridged mode is intended for driving loads with a total impedance of 8 ohms or greater.In Bridge Mode you will combine the power of both channels into one speaker. You will have a large amount of power available so carefully check the power handling of your speaker before operation.RACKMOUNTING TIPS•It is a good idea to mount this in the bottom of a rack frame. Supporting the back of the unit may be necessary for portable or road use. The APX1500 mounts into a standard 19u rackmount.•ALTO amplifiers are well shielded; however, mounting low-level electronics some distance away from power amplifiers is common practice to reduce the possibility of electromagnetic interference into the low levelunits, which may sometimes be unusually susceptible to picking up such interference.•When wiring a rack, it is good installation practice to route all AC wiring along one side of the rack and all audio wiring along the other side to avoid coupling AC-borne interference into the audio.6SPECIFICATIONSPOWER SPECIFICATIONS•*******************%THD,bothchannelsdriven,230V:o4Ω: 2 x 550Wo8Ω: 2 x 350W•Power EIAJ@ 1% THD, both channels driven, 230V:o4Ω: 2 x 750Wo8Ω: 2 x 370W•Bridge Mono Mode:o8Ω: 1 x 1500Wo16Ω: 1 x 740WELECTRICAL SPECIFICATION•INPUT SENSITIVITY: 1.0V•INPUT IMPEDANCE: 10 KΩ unbalanced•FREQUENCY RESPONSE: (at 10dB below rated output power) 20 Hz~25 KHz (+0/-3 dB)•VOLTAGE GAIN: 32 dB•DISTORTION: (SMPTE-1M) <0.5%•S/N ratio: >110 dB•Inrush Current at initial switch on: 8.24A•Inrush Current after power supply interruption: 9.30AGENERAL SPECIFICATIONS•PROTECTIONS: ON/OFF, muting, DC-fault load grounding relay.

If users are not allowed to make changes to the radio test specifications, a password may be entered here andmust be entered to gain access to the Edit Specs screen.Reset Password• After a password has been entered, the only way to remove it is to enter a ResetPassword. This Reset Password can be provided by VIAVI Tech Support(*************************************).• After this value has been entered, press the Reset Password button and the password protection will be removed and a new password may be entered if desired.Edit Specs ScreenInfo lines• Allows three lines of user text to be entered that will be visible at the beginning of the printout in the Test Results file. These could be used to identify a Technician ID, CompanyName or anything that might be useful at the beginning of the printout.F1 – Save As• Save all modifications to specifications to a user specified file. Information on all models is saved in a single file.F2 – Save• Save all modifications of specifications to the currently loaded specification configuration file.F3 – Recall• Recall a saved specification file from memory.F4 – Recall Current Radio• Interrogate the connected radio for model number and show the specifications for that radio.F5 – Cable Loss• Access to the cable loss measurement application.Note: This is one of the first things that should be done prior to testing a radio.F6 – Restore Defaults• Resets specifications to the factory defaults. Note, these values are not permanently stored unless you answer yes when prompted or press the Save Key. This does not impact Radioselection, Info lines, Offset or cable selections.** This operation should be performed after updating the application to a new version.Model Selection• This is used to access the specifications for supportedmodels. Note that the specifications used when testing aradio are automatically determined after the radio modelhas been identified at the beginning of a test sequence.Copy• Copies currently selected Cable to:• All Portables• All Mobiles• All RadiosCopy (continued)• Additionally allows copying entries in the info lines to the selected list.Note: This will automatically save to the currently selected specification file.Offset / Cable Loss• These values are used to correct the power meter for TX Tests and RF Generator for RX Tests. If you are using an external 6 dB high power attenuator, you can enter a negativevalue as an offset. You can additionally use a cable sweep plot to compensate for a testcable. This feature is primarily needed for testing or aligning Transmitter power levels.Note: If it is not possible to perform the cable sweep, enter a fixed negative value in the offset field to compensate for the connecting cable. This value will be used at all frequencies tocompensate the power meter. A higher loss value entry would cause the Power meter to read higher values.• The offset entry will be applied in addition to a cable loss selection.Power Levels• For Portables and Mobiles, the default values should match the MIN and MAX values in the radio’s code plug. These are the TEST MODE power levels that Auto-Test uses. Auto-Test cannot transmit the user programmed power levels.Reference Oscillator• These values are used for test evaluation only. If Alignment is selected, the radio will be aligned to within 30 Hz error. Note that an External Reference is recommended.RX BER Tests• The number of frames is the number of frames that are averaged in the radio prior to reporting a BER reading. The BER Level is the RF Injection level from the 3920. The radio should have 5% or less BER at this test level.Cable 1 - 5• Sweep up to 5 differentcable plots. These areinitially flat with nocalibration. After makinga selection, prompts willbe provided for cableconnection and thecable insertion loss willbe measured.More• Access to Delete cabledata or Modify cabledata.Test Cable CalibrationReference Cable• The 3920 will use its spectrum analyzer and tracking generator to sweep a reference cable and will establish this sweep as a zero reference.• This cable is used ONLY for calibration purposes and will not be used for testing the radio.Getting more accurate results• To obtain better results from this process, use a 3 or 6 dB attenuator at the end of the reference cable that is connected to the T/R port of the 3920. This will improve the VSWR ofthe cable when it is connected to the Radio Testing Cable.Reference Cable Sweep• Gen port -> Reference Cable -> 3 or 6 dB Attenuator (optional) ->TR portRadio Testing Cable Sweep• After the Reference cable sweep has been completed, you will be prompted to connect the Radio Testing Cable in line with the Reference cable. The 3920 will again use its spectrum analyzer and tracking generator to sweep the combined cables and will plot the difference between the two sweeps as the insertion loss of the cable that was added.Radio Testing Sweep• Gen port -> Reference Cable -> 3 or 6 dB Attenuator (optional) -> Adapter -> Radio Testing Cable -> TR portNOTE: The on-screen instructions make no mention of the use of an external attenuator for this calibration.Results of Cable CalibrationCable 1• This calibration wasperformed as directedwithout the use of the 6dB external attenuator.Cable 2• This calibration wasperformed with thesame Radio Test Cablebut a 6 dB attenuatorwas used as explainedabove.Cable 3• This calibration wasperformed with theexternal 6 dB attenuatorand a high quality, lowloss, double shieldedRadio Test Cable.The Difference• Results will vary depending on the quality and length of the test cable. This test was done with a 3ft RG-58 test cable.• Notice that Cable 1 response is not as smooth as the Cable 2 response. These waves are caused by a VSWR mismatch at the point where the cables are connected together. Use ofthe 6 dB attenuator at this junction improves the VSWR and minimizes some of thesestanding waves.The Impact• When calibrating the transmitter power, even small amounts of error in the insertion loss measurement can cause the radio to fail the test. An insertion loss of 0.4 dB that is notaccounted for can cause up to a 10% error in power measurement.• With Dual Band radios, it is important to note that the insertion loss at low frequencies is less than the insertion loss at higher frequencies so one fixed entry for cable loss will not correctthe power meter in both bands correctly.Cable Loss - Modify DataIf loss values are already known, it is possible to create a trace offset through the Modify Datafeature.This allows creation of banded loss factors with known loss values. Enter negative values to account for loss.Cable 1• This is a standard TraceSweep.Cable 2• This trace was createdby entering band specificoffset levels.• Use this when:o Appropriateadapters are notavailable.o The trackinggenerator optionis not installed.o When cable lossvalues areknown.Cable 3• Modified trace allows power meter matching to a Bench Power Meter standard.View ResultsDisplays the most recent test result.• Shows Time Date stamp along with the 3920’s serial number and version information for both the system and the application.• Shows radio model, serial number along with radio software versions and configurations.• Shows the Flash CodeLoad File• Allows a different test results file to be loaded and displayed.Print Results• Prints the test results to a printer that is connected to the 3920 or a network printer if configured for this in the systems printer configuration screen.Clear• Clears the currently displayed results from the screen.Copy Results to USB• Copies ALL test result files from the 3920’s hard drive to a connected USB flash drive.Clear Results Data• Deletes all test results files from the 3920’s hard drive.Running the Auto-Test, Step by Step1.
