I was looking for a simple mixer with eight stereo inputs and four stereo outputs. Couldn't find one anywhere until I came across the RX1602 mixer and the DS2800 splitter. They are totally quiet, no hiss or hum that I can hear.
The DS2800 can be used as a mono splitter with eight outputs or as a stereo splitter with four ouputs. This means there is no single stereo main output control, you need to operate two controls, one for left channel and one for right. My solution is to pre-set these and use the input level controls of the RX1602, which usefully have a level and balance control for each input.
The XLR connectors allow for using two (or more!) DS2800 units together, so for example with two of them, you could split the mixer output into four stereo signals.
A very useful piece of kit.
