Inputs INPUT CHANNEL A&B

With an input sensitivity of 775 mV = 0 dBu and an input impedance of 20 k ohms, the electronically balanced inputs – INPUT CHANNEL A&B

–are meant for the connection of control amplifiers, audio controllers, mixing consoles, etc.

Peripheral pieces of audio equipment are either connected via the XLR- type input connectors or using the parallel-linked binding posts. For the latter option you can utilize the supplied screw-plugs. Thus, carrying the audio signals through to feed additional power amplifiers can be conve- niently achieved without the need for special split-cables.

The XLR-type input connectors’ pin-assignment is in accordance to the IEC 268 standard:

In case the controlling device does not supply balanced output connec- tors, it is also possible to configure the connectors for unbalanced ope- ration. Therefore, the common ground (pin 1) has to be connected to the

(–)input (pin 3). The audio signal is now solely fed through the (+) input (pin 2).

So, to be able to entirely make use of all the advantages the electroni- cally balanced input stage offers – like the suppression of humming and interference noise – it is beneficial to re-establish balanced input con- nection whenever possible.
