Listening test passed aswell. I did not work out the LEDs yet. I think it depends on the case I am going to buy. Before I am going to buy an expensive case I want to make sure everything is fine though.Seems like it is working.
Any idea what kind of LED indiction you want (see post #160)
R+ = 4 (P2Off Board Output) positive board -> (insert filters here later) -> pin-3 XLR
L+ = 3 (P2Off Board Output) positive board -> (insert filters here later) -> pin-1 XLR
R- = 4 (P2Off Board Output) negative board -> pin-4 XLR
L- = 3 (P2Off Board Output) negative board -> pin-2 XLR
I already installed the 680 Ohm resistors. Is the amplifier currently playing in high or low gain without a switch installed? The DT770 (80 Ohm) is easily powered by the amplifier with a lot of headroom.You are not the only one to make that mistake.
I wired a headphone plug incorrectly once which made me think something sounded really different in that headphone compared to others.
When I put it on 'backwards' it sounded normal again.
Glad to hear it works well. Perhaps install the gain switch on the positive board and figure out what gains you need.
Correct?Running on mains = max Uout: 14.4V
600 Ohm: 0.35W
300 Ohm: 0.7W
150 Ohm: 1.3W
60 Ohm: 1.1W
32 Ohm: 0.6W
