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.

AP音频分析仪的一般操作和使用方法1

AP音频分析仪的一般操作和使用方法贴子发表于：2010/3/15 23:20:01模拟信号发生器：单击工具条开启模拟信号发生器（双通道独立输出）。

•Wfm: 选择产生信号波形。

一般测量使用Sine / Normal（典型正弦波波形），是由模拟部分硬件产生的低失真度的信号，20Hz –20KHz时失真度< 0.0001%。

•Frequency: 设定信号频率，Sine / Normal模式下可设定频率范围：10Hz –204KHz。

输入时可加单位“k（千）”。

•Fast / High Acc.: 选择快速（+/-0.5%）或高精度（+/-0.03%）模式。

快速模式适合于一般音频测试，建议在需高速自动测试中使用。

高精度模式产生精确的信号频率，但需150mS –750mS的设定反应时间，建议手动测试时选用此模式提高测量精度。

•Amplitude: 设定信号振幅。

平衡输出时可设定振幅：<10uV –13.33Vrms。

非平衡输出时可设定振幅：<10uV –26.66Vrms。

输入时可加单位“n（纳），u（微），m（毫）”。

注意因信号发生器的输出阻抗的差异，和DUT输入阻抗的差异，会导致DUT输入端的信号电压偏低于APWIN的设定电压。

•OUTPUT ON/OFF: 信号发生器输出开关。

按钮绿色是开启，灰色是关闭。

•Auto On: 如选中，在扫频开始时自动开启信号发生器，结束时自动关闭信号发生器。

•CHA On/Off: A通道输出开关。

按钮绿色是开启，灰色是关闭。

作用在信号发生器输出开关前。

•CHB On/Off: B通道输出开关。

按钮绿色是开启，灰色是关闭。

作用在信号发生器输出开关前。

•Invert: 信号相位180度反转。

可分别控制A / B通道。

通常反转B通道相位用于Dolby ProLogic测量。

•Track A: 如选中则同时设定A / B通道的振幅，反之分别设定。

•EQ Curve: 选用APWIN或自定的均衡器曲线。
