OK, that's a strange one....

I used to have some pop and drop issues when I was running 44.1K out of a laptop to the DCX. Found it was a grounding problem. Using a 75 ohm to 110 ohm transformer helped, as did better grounding. But I didn't relate that to the DCX, just to my bad wiring.

Simple fix - do you think it hurts to up-sample with your sound card? Since the DCX up-samples to 96/24 anyway. Do it in software, do it in the soundcard, do it in the DCX. Not sure which is best. That doesn't help you with the CD player, tho.

I wonder if a 75>100 ohm transformer would help?

I go for the 96 up-sample in the sound card. It works.
Unfortunately we don't have real grounded power in this house.

google it.
Build the hum detector that Whitlock/Rane suggests.

Pin 1 of all outputs and all inputs goes direct to Chassis at the in/out socket.
Never to the PCB, nor other grounds, inside the chassis.
I will check this! Thx

Default Pilgham Audio SRC - Where to connect V+?

Took my dismantled DCX off the shelf after years. I once bought a Pilgham Audio SRC/Clock but mislayed the manual and so I wonder where to connect V+ ...

Can someone provide a picture or simply tell me what pin ist to be fed with V+?

THX!

SRC/clock mod installation instructions

1. Disassemble R34 (22 ohm) on solder side of DSP board

3. Disassemble IC1 (CS8420) on component side of DSP board
Preferably with hot air or cut the pins carefully or lift the single pins with a needle and soldering iron
Avoid any forces on the PCB !

4. Assemble female 26-pin ERNI connector instead of IC1
a, "Straighten all pins of row B a little bit so that they touch the pads of CS8420
Flatten all pins of row A"
b, Solder row B: B1 = pin28 ... B13 = pin16
c, Bend (45) long side of pins close (~1mm) to the header and cut pins on long side of pin header
d, "Insert pin header: A1=pin1 . A10=pin10
underneath pins of SMD connector"
e, Insert wire: A3 = 9volt (IC7,pin1 or connectorX3,pin3)

Modifications for Behringer DCX-2496

1. ‘Dull sound’ problem (digital input)
I wonder if this was a near permanent failure in my DCX? Even though I used analogue input.
I could not get my active to sound as good as passive. That why I gave up that project.

Now I suppose I have to fit the "Oettle Mods" and steel my self up for trying again.

The SMPS of my DCX broke down too - it turned out to be one of those bad elco cases. The 400V 47uF directly behind the (high voltage!) rectifier to be precise. It showed a slightly bulged top. After all it was an inexpensive and easy fix, I would say check that elco first.

I've wondered in the past if one could use a
Li Shin LSE9910A03 in a PINCH?

I agree, chances are the thing has something simple wrong.

I have many ideas how to improve the stock supply, but you need to fix it first.
