4. CONNECTIONS

4.1CONNECTING POWER TO THE AVM 30

Connect the power cord to the back of the AVM 30 and then to a 105 to 130 Volt, 60 Hz AC outlet.

4.2AUDIO 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.

Every 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 S/E, which accept analog signals only (see section 7.4.5).

4.2.1 DIGITAL AUDIO INPUTS AND OUTPUTS

Digital Audio-In connections are made through a coaxial (RCA), optical (TOS), or balanced (XLR) cable. From the factory, DVD and SAT are set to Digital-RCA, whereas CD, TAPE, TV, VCR, and AUX are set to Analog-DSP.

The highest transmission quality is achieved with the AES/EBU connection. The AVM 30 provides one such input. The S/PDIF-RCA connection offers the next best digital transmission – use for source components with digital RCA outputs. For source components with Toslink outputs only, use S/PDIF-TOS. Any digital input may be assigned to any number of Sources that are set to ‘Digital’ (see section 7.4.5).

Note: An external RF demodulator is required if using a Laser Disc player with Dolby Digital/AC-3.

Digital Rec-Out can provide a signal to the digital audio input of a Mini Disc recorder, CD-R, etc., from any Source set to ‘Digital’ or ‘Anlg-DSP’ (see sections 7.4.5 and 7.4.7).

4.2.2 ANALOG AUDIO INPUTS

Left/Right Analog audio connections are made through a pair of interconnect cables – typically white or black for the Left channel and red for the Right channel.

Note: Connect both the digital and analog outputs from source components that have both types of connection (e.g. DVD player) – ZONE2, ZONE3, and RECORD require analog audio connection unless set to ‘copy’ MAIN (see sections 5.2.1 and 7.4.5).

Caution for DTS: With DTS-CDs or DTS Laser Discs, do not use analog connection if your player does not have the DTS logo on its faceplate, otherwise a loud noise will be produced at the analog outputs of the player. Players that have the DTS logo can pass a DTS-encoded signal through their digital outputs, though they do often require a change in their setup menu to enable it (see player’s operating manual).
