does anyone know where I can find a six channel volume control to make my own home thater preamp. my dvd player has six channel outputs and built in DD and DTS processers so I basically need a six channel preamp with a remote control volume control. Any suggestions would be appreciated.

Those are the only decently priced ones i found. There is a supplier in usa, builds them at almost three times the price as small series.
Problem with thel - they don't ship to overseas. I got them shipped through my parents in germany.
But - they are excellent - the pots, my parents as well

Hi,
A disadvantage of ganged pots is imbalance at high attenuation.
Some manufacturers try to select or trim tracks on their pots to improve their tracking.
BUT with multi-channel pots this may be either expensive or impossible.
The effect is that signals to different channels will sound off centre or in the wrong location at lower volumes and may change position as you adjust volume.

Hi,
you could also use a 6-channel microcontroller based relay attenuator which is controlled by a simple mono pot attached to the internal A/D of the microcontroller if you want to have a pot to control it. Or you can use two pushbuttons (up/down) and then can use a remote control for setting the volume. Unfortunately this solution is more expensive

Hi,
12 steps starting at 0db in 6db increments ends up at -66db, or you can make uneven steps starting at -30db or whatever, or gang two switches in series, 12db increments followed by 1db increments now we have -143db in 1db steps.
Just design it to suit your preferences.

Another 6ch pot on ebay
Hi,
i found another 6 channel pot with motor from ALPS on ebay. I noticed this seller a few times before but i will stay with my relay attenuators
Here is the link:

A link to the datasheet (PDF) is in the description.
