English Switching on P429 operation The POWER button switches the unit on and off.

POWER Mode switches CH3 CH2 These switches allow the two pair of amplification channels to be independently configured in three different modes. CH1 4–16 OHMS.
Connecting loudspeakers loudspeakers Notes on making speaker connections << Do not make any connections to any amplifier while it is switched on. We recommend that your amplifier is completely disconnected from the mains supply before starting. Before switching your amplifier on for the first time after connecting to speakers, please check all connections thoroughly.
Dual mono / Bi-Amping In this setup, only one interconnect is required for each pair of channels. The L and R output of the two channels of your audio/video device (such as the Arcam 550/850) should be connected to the IN1 and IN3 input of the P429, respectively. CH4 CH3 CH2 English WARNING: the strip of metal on the speakers connecting the low frequency (LF) terminals to the high frequency (HF) terminals MUST BE REMOVED.
Bridged mode In bridged mode, only the positive (red) speaker outputs of each P429 channel are active. No connections should be made to the negative (black) speaker terminals. WARNING: If your speakers support bi-wiring, there will be a strip of conductive metal connecting the low-frequency (LF) terminals to the high-frequency (HF) terminals; this MUST NOT BE REMOVED in a bridged mode system. WARNING: Do not make any connections to the other speaker terminals, doing so will severely damage your amplifier.
English troubleshooting If you are having trouble with your amplifier, check the following items. No sound Sound cuts-out unexpectedly Check the following: << The P429 power amplifier is correctly plugged in and switched on << Your audio/video source (e.g. preamplifier) is correctly connected, the correct input is selected and it is not muted << The P429 is not in protection mode, as described in the next section. The P429 may enter a protection mode, depending on the fault being detected.
