Where is the fuse in a xr1220 mixer.


which fuse?? main fuse? output fuses?

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

Why does only one channel volume work? I am pretty sure it worked when tested it before I bought it. I have both speakers hooked up and I have a mixer connected to the power amp. Thank you


The 'problem' could be anywhere in the chain - amp, mixer or speaker. YOU need to do some swapping to isolate which product failes. Swap channels, inputs and outputs and speakers.

Wish to run sm450v2 Mackie powered speakers thru a Peavey XR8600


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.

Connecting two powered mixers


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.

Signal Light Problems Yamaha P2500


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.

Amp c352 TI 1515456 failure


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.
