 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

 Connecting to the [SPEAKERS] termi-

nal

CAUTION

Make sure that the power is turned off, to avoid the dan­ger of electrical shock.

 Binding post connector

• Without plugs

Remove about 15 mm of insulation from the end of
each speaker cable, pass the bare wire through the holes
in the appropriate speaker terminals, and tighten the ter­minals to securely clamp the wires. Make sure that the
bare wire ends do not jut out from the terminals and
touch the chassis.

Symptom Possible causes Possible solution

Reference — Troubleshooting

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.

Check the source voltage.

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.

After disconnecting the speakers, turn on the device without inputting any sig­nal, or lower the volume completely, turn on the device. If the symptoms do not
improve, the device is broken. Contact your Yamaha dealer.

Sound from speakers is distorted. The input level exceeds the setting of the input sensitivity.

The sound is muffled. No high-frequency sound.

When “ROUTING” is set to something other than
“DUAL,” the level of channel B is low.

The sound is filtered. The filter status can be checked in the HOME
screen.

The volume knob of channel B, with which the output balance to channel
A is adjusted, has been lowered.

Adjust the input sensitivity to match the input level with the CONFIG WIZARD
screen.

Change the setting of the filters in the MENU screen (TUNING screen).

Raise the volume knob of channel B.

Symptom Possible causes Possible solution

Cables are not connected appropriately. If the meter does not rise even if
raising the volume knob, there may be problems in connectivity at the
input side. If the meter rises, there may problems at the output side.

The outputs of the mixer connected to the input jacks are lowered. There
is a possibility that the meter does not rise even if the volume knob is
raised.

No sound from speakers.

The panel controls cannot be operated. The panel lock is turned on.

The parameter settings need to be returned to
their initial values.

An indicator does not light in a condition in which
it normally should light. The display is blank.

Level has been lowered with the volume knob. Adjust the volume knob accordingly.

The mute is on. When the mute is on, “MUTE” appears in the HOME
screen.

The protection circuit has been engaged and the output is muted. When
the protection circuit is engaged, the [PROTECTION] indicator lights.

The speaker type is Power Boost mode (PX5 and PX3 only).

—

The Black-out mode is on.

Connect to input jacks and output terminals appropriately. At the output side,
make sure that terminals outputting signals are connected. Refer to “Usage

examples” (page 4) for connection instructions.

Raise the output of the mixer.

Turn off the mute.

Identify what is causing the protection circuit to engage and solve it.

In Power Boost mode, audio signals are not output from channel B. Cancel
Power Boost mode or reconnect the cables.

Turn off the panel lock. Refer to “Panel lock”(page 14) for instructions on turn-
ing off the panel lock.

Return the settings to the initial values. To do this, refer to “Initializing the PX

amplifier” (page 37).

To temporarily make the indicators light and the display work, operate the
panel. To make the indicators light and the display work regularly, turn off the
Black-out mode. Refer to “PANEL SETUP” (page 34) in UTILITY screen.

After starting up again, parameters you’ve edited
have returned to the values before editing.

Reading or writing from/to a USB flash drive
takes a long time.

* If any specific problem should persist, contact your Yamaha dealer.

The device was shut down before the current parameters were stored
automatically.

The USB flash drive contains a number of files. The more files that are
contained, the longer time is required.

When the device is shut down, wait more than 3 seconds after editing current
parameters.

Delete files the PX amplifier does not need.
