Balanced Inputs

Note:

Accepts a signal from a preamplifier with balanced outputs via a high quality XLR connector. The use of good quality balanced line cable into the balanced input cause the input signal to be relatively immune to noise and external effects caused by the use of long interconnect cables, helps reduce hum loop noise and aids in the cancellation of distortion products.

Refer to Chapter 13 “Specifications”, for detail on input sensitivity and impedance.

Please set the input configuration switch to the appropriate setting.

The pin assignments of the balanced XLR connectors are as follows:

Pin 1: Signal ground

Pin 2: Signal + (non-inverting)

Pin 3: Signal – (inverting)

Shield ground: Chassis ground

Please refer to the operating manuals of your balanced output line level source to verify that the pin assignments of the output connectors correspond to the 350 balanced inputs. In the event that they are not compatible, the interconnecting cable will need to be altered to suit.

For more information regarding balanced interconnects, please refer to Chapter 7 “Maximising System Potential”.

Unbalanced Inputs

Accepts a standard single-ended input pair (RCA) from preamplifiers with single-ended outputs. The connectors are high quality gold plated sockets which are highly conductive, corrosion resistant, and provide less potential for corrosion induced distortion. Inputs are clearly marked Left and Right, indicated by a black and red ring respectively. Care should be taken to maintain channel integrity.

Refer to Chapter 13 “Specifications”, for detail on input sensitivity and impedance.

Please set the input configuration switch to the appropriate setting.

Input Configuration Switch

This toggle switch allows selection of either the balanced or unbalanced inputs.

Input leads should be connected to one type of input only, i.e. do not connect to both the unbalanced and balanced inputs at one time.
