2.2AUDIO 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 input can be changed from the factory setting to either Digital or Analog audio connection. Furthermore, any one set to analog can be used with Digital Signal Processing for bass management, bass/treble control, time alignment, surround modes, and THX post-processing, or be set to Direct and bypass all digital stages. As well, Auto-Diguses 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, balanced, or HDMI cable. These carry 2-channel PCM, Dolby Digital, and DTS. The HDMI inputs also accept up to six channels of PCM.

Should you need audio from the HDMI output to your display, it’s 2-channel PCM.

Use the HDMI inputs if your display has HDCP-compliant HDMI or DVI input, otherwise use the coaxial or optical inputs. The AVM 50 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’ (except HDMI) 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.
