hey Roberto, no time to answer properly, but yes please send the second connector, just so I have a set. the wire I intended to hardwire initially is 12awg stranded UPOCC and its a tiny bit too big for the holes in the PCB, I can maybe make them big enough or remove a strand or 2 to allow it to fit before soldering. I have some 12awg solid UPOCC that fits nice and snug, but it would be good to have options as the 12awg stranded fits in the connector pins nicely and its what I planned to use for power and output through the whole build. I figured it would fit, fits the amp

clocktower, please go away

I asked Roberto to not solder as an option, I was just surprised o see only one and planned to test with connectors first before final instal soldering

well, np.
I have replaced pin with gold pin in female connector, in some applications. some our cabled, use 2,5mm diameter of wire in this connector with no problem. wire solder (not crimped) +tube on wire, just 2cm length.

Hi, I'm back now,sorry for delay.
with the resistance can try the startup condition, yes. (one res per side)
After, connecting the amplifier. not try a single resistor between + and -. This SMPS also accepts loads on one side.
DPS-600 (without bottom panel) requires a cooling surface, min. 0.8-1 / W. for test eg. heatsink 160mmx40x40 thickness 10mm.
the final testing done in the laboratory, determines that the startup sequence, has a duration of 500ms with 2x373mA at output (2x150R load).
The best fitting both for the heat dissipated, which for EMI, is vertically on a base panel of aluminum 3mm thickness, used as the basis of the case.In this case, we recommend installing the two DPS-600, in central position of the case. This method may help the assembly, making no visible screws on the outside bottom of the lid of the case.

Hi Roberto,

I picked up my dps600 last night, as commented by a few others, they are so tiny compared to the power they produce, certainly gives some options for optimised and tidy enclosure layouts.

I found this comment pretty interesting!


In terms of EMI, is the area marked X or O in the attached image going to have higher EMI levels?

Yellow rectangles indicate general area to be used for signal input output cables. This is my current thinking for my amp enclosure layout. 2 x The Wire LME49830 amps + 2 x The Wire - LPUHP amps (ignore LONG tx leads, just finished testing them) in one 19in enclosure.

Floor of enclosure will be 336mm x 300mm alu 2mm thick + heatsinks for LME amps at either side in area where amp pcb is sitting in photo.
