low frequency content even when no subwoofer is present.
The normal display returns 15 sec. after the last action on any of the channel select
keys, or immediately after the ”>VOL” key is pushed.
3. Zone 2
With zone 2, it is possible to redirect the sound to other audio systems, e.g. in the
kitchen or bedroom. The zone 2 has a separate volume control and input selector.
Adjustments for zone 2 are achieved by holding down the same input knob as
currently selected. When e.g. DVD input is selected, hold down the “DVD” knob on
remote or front panel for approximately 1 sec.
Then the ZONE2 indicator becomes active.
Possible inputs are:
SAT ANLG
TV ANLG
LD ANLG
TAPE1 ANLG
Z1 -> Z2 (Input selected in the main zone is played in zone 2)
Even if an input is defined as digital in the main zone, the analogue option is chosen
in zone 2.
The operation returns to the main zone 15 sec. after the last adjustment made to
zone 2, or by pressing the ”>VOL” key.
4. Delay
To experience the best surround sound quality, it is important that the sound signal
from all the speakers arrives at the same time at the listening position. If the
listening position is placed closer to the rear surround speakers, the sound from
these speakers will arrive earlier at the listening position. In this case, it is necessary
to delay the sound slightly from the rear speakers.
The important issue here is the difference in distance from the listening position to
the front and rear speakers.
The same problem arises if the centre speaker is placed closer to the listening
position than the front speakers.
On some video sources, the video is delayed compared to the audio, due to video
processing. To compensate for video delay, it is possible to delay all audio channels
up to 5ms. This common delay is called “Lip sync”.
The delays can be set directly from the front panel keys by pushing the “SL”, “SR” or
“C” keys for more than two seconds (only AV120/120S) or double-push on the same
knobs on the remote control.
The display responds briefly with the message DELAY, and afterwards the delay
setting for the selected channel is displayed, e.g. SL 5.0ms. Subsequently, the
delay of the extended surround channel SC and “Lip Sync” can be selected by using
the arrow keys.
The delay can then be changed in steps of 1.0ms by turning the volume knob or
