SEIDLER/Soundwork SM16 2016 - Natur/Schwarz

Very nice and tiny line mixer.

It only measures: 230x190x90 mm (millimeters!)

It is powered by 12VDC / 2A. The internal power supply provides +25VDC and +150VDC.

There are 4 mono inputs and a stereo summing unit. While the input circuits are of discrete transistor architecture and transformer balanced, summing is made by a ECC88 tube and there is also a simple optical limiter in its negative feedback. Outputs: transformer balanced.

Every input has a gain control, a very musical passive EQ with 10 frequencies (100; 200; 300; 600; 1K: 1K5; 2K; 3K; 5K; 7K) , a low cut, 12Khz boost/cut switch and a pan potentiometer.

The input transformer can be set to 0 or -6 dBu. Supplementary, there is an opamp powered headphone output. The meters are high quality NOS. The right one shows the gain reduction of the limiter.

I built this mixer for myself, but do not really have the time for using it. This mixer is not a precision tool - it is a musical tool for sub mixes and also nice to give vocals extra flavor.
