Mixer section seems to be working have mixer light action with input but no output to speaker no blown tops on transistors or ic no obvious burnt resistors or diodes no obvious short on transistors or diodes without schematic hate to go much further ..any pica fuses or such that may be blown? any known issues with power transformer? thanks

if the main fuse has blown & the device simply won't power up, replacing it will merely result in another blown fuse - you need to take it to someone who can repair the units' power supply
output fuses blow when speaker wires are shorted, or speakers fail short - they're on the main circuit board, but seeing you're asking, i'd suggest you don't open the unit, but take it to someone who knows what they're doing
hi, normally in any amplifiers or preamplifiers the RCA sockets used only for pre input and output. for speaker out always there will be binding post or speaker sockets, u can connect the pre amps RCA output to ur power amps input. there will be seperate connector for speaker connection in ur power amplifier . You didn't specified the make and model number of ur amplifier and pre. need any further help feel free to contact. ok
The Peavey XR8600 is NOT just an amp, but a powered mixer.
To SAFELY use this with your powered speakers, connect those speakers to the MAIN and MONITOR outputs on the front of the unit with 1/4 inch INSTRUMENT rated cables (NOT speaker cables).
To safely leave the power amps in the XR8600 with no output loads, plug GROUNDING plugs into the POWER AMP 1 and 2 input jacks on the front. This will prevent the power amps in the XR8600 from running with no load which COULD damage them.
Make the grounding plugs from 1/4 inch mono plugs by jumpering the centr aand sleeve terminals of the plug.
Hi, If you have small electronics knowledge this might help you. First fine in each mixer the amplifiers line In if your mixer has two amplifiers then you have four line In. Disconnect this line from your mixer and build a circuit Line out multiflier. You can use op amp for this application this is a simple circuit. You made two input and four outputs. If you are interested i can send you a schematic diagram.
Stereo amplifier = two channel..A and B.
1. Make sure that your stereo audio mixer has an output from LEFT going to amp channel A and output RIGHT going to channel B.
2. Check that the "Pan" control on your audio mixer is set to the 12:00 position.
3. Inputs to mixer...make sure the music/microphone input channels "Pan" controls are also set for 12:00 as well.
It sounds like yo shorted the speaker wires together for a short time and smoked the output section of the amp. The amber light is an indication that the amp is in protect mode. If you attempt to power up the amp and still have the amber light even with all speaker wires disconnected, the amp needs repair. The output transistors for that side will need to be replaced.
