sa32: scalable summing power
The SA32 Summing amplifier is primarily designed for a DAW system where high performance analogue summing is required. It is a summing amplifier, and only that. That is why its sonic performance is exemplary - because there are no squidjy bits in the way.
The basic SA32 is fitted with 32 channel balanced analogue inputs - 12 stereo and 8 mono.
All source inputs are accessible via 25pole Female Sub-D connectors on the rear panel. This pin-out is similar to the standard DigiDesign D-sub layout.
Furthermore, there is a balanced XLR stereo main Mix output, a semi-balanced TRS monitor out and a semi-balanced TRS meter out. A handy monitor output control is available on the front panel - so you can connect it directly to a studio patch for direct routing to your favourite near field speakers.
A special feature of the SA32 is its expandability. There is a 15-pole female Sub-D connector providing direct access to the main-mix busses and to connect additional SA32 units (Yes...32 SA32 units). A large-scale summing system can therefore be obtained in a very simple manner. Up to 128 channels can be setup without any noticeable audio degradation.
The Front panel contains a 24-step precision gain switch with a range is from -5,5dB to +6dB in 0,5 dB steps.
A power switch with a green LED is located at the right side.
For long- term stability and pristine sound quality - there is no secondary control of the 32 inputs. In short, what is needed to be in the circuit – is what is in the circuit.
Nothing else.
The first 12 stereo inputs are bussed respectively to left-right. The last 8 mono inputs are bussed directly to left+right. These can be changed to stereo inputs via internal jumping.
The SA32 is mounted in a standard 1 Unit 19” Rack enclosure.
