7.4.7 A-D/AUDIO-OUT FORMAT
In the A-D/Audio-Out Format menu you can re-configure the Surround and Rear channels, set analog to
digital conversion parameters for the digital Record output, and configure the balanced analog outputs.
Reverse Surrounds/Rears:
If you’re using a 7.1 speaker system and prefer the Rear speakers instead of the Surrounds when 6-Ch S/E
is selected, set REVERSE SUR/REAR to ‘Yes’ and r
e-connect the AVM 20 as follows: Surround outputs on the
AVM 20 to the Rear inputs on your amplifier, and the Rear AVM 20 outputs to the Surround amplifier inputs.
The 6-Ch Surround inputs will now play through your Rear speakers. The AVM 20 flips the SUR/REAR
channels back to normal whenever THX is turned on for the 6-Ch input or when any other input is selected,
thereby maintaining correct speaker configuration at all times.
Copy Surrounds to Rears:
When playing material or using a Mode that has Surround channel information but no Rear information,
setting this to ‘Yes’ plays the Surround channel out of both sets of speakers.
Sampling Frequency (fs):
When a Source that is set to Anlg-DSP is copied from MAIN to RECORD, the analog signal is converted to
digital using the AVM 20’s high-end A/D converters, and sent to DIGITAL1. This is useful for recording analog
music on a CD burner or computer with S/PDIF input on the sound card. You can select from 44.1, 48, 88.2, or
96 kHz sampling rates. Recording level is set by the input level in menu 6 (see sections 5.2.1 and 7.4.6).
This is also the signal processing rate for MAIN. Other than AnthemLogic, certain surround Modes do
not function when ‘2-Ch Anlg-DSP fs’ is set to 88.2 or 96 kHz. Therefore leave this set to 44.1 or 48 kHz
unless a recording is being made, and then use 48, 88.2, or 96 kHz only if the equipment connected to
DIGITAL1 and DIGITAL2 is capable of accepting those sampling rates.
For the 6-Ch S/E input, a separate setting is used so that bass management, time alignment, Mode,
Bass/Treble, Audio Group Delay, and THX can be performed at the same high resolution that DVD-Audio and
SACD provide. When 6-Ch S/E is copied from MAIN to RECORD, the DIGITAL1 output is a 2-channel downmix.
Bit Rate of DIGITAL1 when MAIN is copied to REC:
Choose from 16 or 24 bit output, to match the recorder. At 16 bits, dither is added to improve low level signals.
Output of DIGITAL2:
Set it to have the same output as DIGITAL1, or a fixed output from any Source set to Digital (DVD, SAT, etc.).
DIGITAL1 and DIGITAL2 transmit data from digital sources in the same format it comes in – if it’s Dolby Digital
or DTS encoded, it stays that way and can be linked to other digital equipment.
Balanced Output:
If the Balanced CENTER2 and SUB2 outputs are not in use for a second Center channel or Subwoofer in
MAIN, they can be used as Balanced ZONE2 L/R outputs (see section 4.2.5).
