Swissonic ZM 4

Perfect mixer for managing multiple zones

I used one of these for a fixed installation at an embassy's conference rooms. It's a great way to be able to rout various sounds to varius destinations, using online one small, easy to use mixer.

Unfortunately, the four zones each are mono zones, so you can only have a max of two stereo zones, but heey, for speech and some multimedia sound, this is far okay. Great price too!

useles crap

Total gain of line inputs to outputs ( gain and volume pots all way up ! ) is only about 3db,but mic input distorts when income signal is higher than 18 mV.

Gain regulation on channel is not real gain-it is more like another volume regulation in serial with existing volume regulation on channel.

So if you have any audio source with level beetween 18 mV and 1,2V there is no way to process it correctly and without distortion through zm4 .

Output meters are also semi-useless. When first red led is lightning there is still no full output level,when the second red light is on the output is near +2db.
