2.2 AUDIO CONNECTIONS
There are two methods of transmitting audio signals: Analog and Digital. Analog is an electrical waveform
representation of sound and requires one cable for each channel. Digital represents sound using a sequence
of numbers and requires only one cable for all channels.
Any audio input in the AVM 30 can be changed from the factory setting to either Digital or Analog, except
2-Ch BAL and 6-Ch, which accept analog signals only. Any analog input can be set to be used with
Digital Signal Processing for bass management, bass/treble control, time alignment, surround modes,
and THX post-processing, or to Direct and bypass all digital stages. As well, Auto-Dig uses the digital
connection when there’s a digital signal at the input, and when there isn’t, it switches to analog
connection with DSP. For more information see sections 3.2, 3.3, 3.5, 4.7, and 4.8.
Digital Audio Inputs and Outputs:
Digital audio source components can be connected with a coaxial, optical, or balanced cable. These carry
2-channel PCM, Dolby Digital, and DTS.
Use the coaxial input if the source has coaxial output, otherwise use the optical input. The AVM 30 also
provides one balanced AES/EBU connection, which is used on professional equipment. Any digital input can
be assigned to any number of Sources that are set to ‘Digital’. To change digital audio connection from the
factory default assignments, see section 3.5.
Digital Rec-Out can provide a signal to the digital audio input of a Mini Disc recorder, CD recorder, etc., from
any Source set to ‘Digital’ or ‘Anlg-DSP’ – see sections 3.5 to 3.7.
Analog Audio Inputs:
Analog audio connections are made with RCA or XLR cables.
If you are going to use ZONE2, ZONE3, or RECORD, connect both the digital and analog outputs from the
source components. ZONE2, ZONE3, and RECORD require analog connection unless they’re set to ‘copy’
MAIN (see sections 3.5 and 4.3).
6-Ch Analog Input:
The 6-Ch input is for connecting DVD-Audio and multichannel SACD players. When 6-Ch is selected, the
video signal from DVD input is routed to the video outputs by factory default – to change this, see section 3.5.
