Signal processing in PX amplifier

The PX amplifier gives you comprehensive control over the sound with input processors and speaker processors. The signals from the input connectors are processed in input processors equipped in each input connectors. The processed signals are added or divided depending on the set routing, processed finally with the speaker processor in each channel, and output from the [SPEAKERS] terminals.

Refer to “TUNING screen” (page 25) in “Panel Operation” for details on the processing.

Input sensitivity and amplifier gain

The PX amplifier specifies the input sensitivity/amplifier gain from two input sensitivities or two amplifier gains. Input sensitivity controls the input signal level so that the amplifier can output the maximum power. If signals over the input sensitivity are input, the built-in limiter of the PX amplifier is activated. If the volume is lowered, the input sensitivity rises and the amplifier gain declines. Maximum power is constant if the volume is lowered. For example, if the amplifier gain on the PX10 is set to 32 dB, the input sensitivity is +9.3 dBu and the maximum output power is 1,000 W (if speaker impedance is 8Ω). When the volume is not lowered (0 dB), output power of 1,000 W results with +9.3 dBu input. When the volume on the PX10 is lowered to 6 dB, the input sensitivity is +15.3 dBu (9.3 dBu + 6 dBu) and the amplifier gain is 26 dB (32 dB - 6 dB). If a +15.3 dBu signal is input, maximum output power of 1,000 W is gained.

Rack mounting

The PX amplifier can be mounted in an EIA standard rack (2U size).
Precautions for rack mounting
This device is rated for operation at ambient tempera­tures ranging from 0° to 40°C. When mounting the device with other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified upper limit, resulting in impaired performance or failure. When rack mounting the device, always observe the following requirements to avoid heat buildup:
• When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave more than 1U of space between the device and other equipment. Also, either leave the open spaces uncovered or install appropriate ventilating pan­els to minimize the possibility of heat buildup. Multiple PX amplifiers can be mounted by stacking vertically.
• To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If the rear of the rack cannot be left open, install a commercially available fan or similar ven­tilating option to secure sufficient airflow. If you have installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and/or fan unit manual for details.

Speaker connection

The display automatically turns off if the PX amplifier has not been operated for a while.
[PROTECT] indicator lights and an “OUTPUT CURRENT OVER” message appears on the dis­play.
[PROTECT] indicator lights and “AMP TEMP TOO HIGH” message appears on the display.
[CLIP/LIMIT] indicator lights.
Power does not turn on. Power suddenly turned off, and immediately turned off even when turning on again.
For the protection of the display, the display automatically turns off if the PX amplifier has not been operated for 20 minutes.
If the Black-out mode is on, the back light of the display automatically turns off when PX amplifier has not been operated for around 10 sec­onds.
There is a short at the speaker terminal, amplifier terminal or wire, and circuit protection has been engaged.
Since the impedance of the connected speaker is excessively low and the amplifier is overloaded, circuit protection has been engaged.
Because the internal temperature is excessively high, thermal protection has been engaged to protect the circuit.
Because the input signal is excessive or the output exceeds the rated voltage, the signal is clipped or the limiter has been engaged to protect the circuit.
The power supply connected outlet is significantly different from the rated range.
Because the internal temperature is excessively high, thermal protection has been engaged to protect the circuit.
The output level is excessively high. Lower the output level.
The device is broken.
Press any key on the front panel or rotate the main knob to turn on the display again.
Press any key on the front panel to turn on the back light of the display. If the Black-out mode is set to off, the back light does not turn off even if the PX amplifier is not operated.
Turn the power off and check for a short in the speaker terminal or amplifier, wire, etc., and turn it on again.
Check that the speaker has not been damaged and that total impedance is not excessively low, and review the speaker connection.
Check the amplifier ventilation conditions and take appropriate measures to improve the airflow around the amplifier. Leave the amplifier off until the internal temperature goes down, and then turn it on again.
Lower the output level of the device connected to the input connector, or lower the volume of the amplifier.
