Pioneer GM-X924 owners manual

[sdoom]

Hi,

does anyone have a user manual for a GM-X924 ? Pioneer web site only offers a quick-spec datasheet and the European helpdesk doesn´t offer older model´s literature.


It seems that the amp can not only be bridged (channel 1+2 / 3+4) for more output power , it seems that it is also possible to put channels 1+3 / 2+4 in parallel for 1 Ohm loads


Thanks,
Stephan

Looking at the service manual, I don't think that's possible.

Hi Perry,

as far as I know Pioneer is US - engineered ? I know you guys can and do create fabulous things but sometimes engineers come up with something .... let´s say "weird"

I found a 924 user manual and , in deed, it is possible to "interconnect" channels 1+3 , as well as 2+4 . That´s what Pioneer calls a " 2 channel stereo mode" ..... who ever it needs ...

An externally hosted image should be here but it was not working when we last tested it.

But could you do me a favour? As you mentioned you have the service manual : Idle current is set while using a 1kOhm resistor on the inputs and a 4 ohm load connected to the outputs like other Pioneer models ? If so, could you tell me the idlöe current value and the voltage output of the SMPS ?

Thanks again,
Stephan

Initially, it sounded like you wanted to add the output stages together to act as a single, low impedance channel. Similar to what some of the ESX amps could do. That diagram simply shows bridging.

Email me if you want the service manual.
