Input and output to the sidechains is assignable to and from the six channels. Assignable LFE filters on the input and sidechains along with the key input provide integrated bass management. Flexible sidechain routing, trimming and filtering make this a powerful and responsive tool for surround mixing. The 8051 uses the same feedback topology as the 33609 compressor and includes the same transformers, diode-bridge gain control and discrete power amplifiers in the audio path. 8051 5.1 Compressor Page 1 Issue 2 8051 5.1 Compressor User Guide Dimensions Units U Depth mm (inches) Height mm (inches) Approx.

No specific air conditioning is required for the racks, provided that there is a free flow of air through the rack from front to back, and that the ambient air is maintained below 30 degrees centigrade. Therefore the racks may be stacked.
