DSP OPTION
LIP SYNC DELAY
DSP Options has the feature “Lip Sync Delay” whose function is to match
any delay that may occur in the picture relative to the audio.
By varying “Lip Sync Delay” from 0ms to 120ms, one can delay the audio
output in order to synchronize it with the video image.
TONE CONTROLS
The T 748 has two Tone Control levels – Treble and Bass. Bass and Treble
controls only aect the low bass and high treble leaving the critical
midrange frequencies free of coloration.
These controls allow one to tweak on-the-y, the frequency response of the
source during playback. The control setting could be adjusted by navigating
through the Tone Controls’ OSD menu via a combination of [ ENTER ] and
[A/S/D/F ]keys.
Maximum and minimum values for all three Tone Control levels are ±10 dB.
“Tone Defeat” gives one the choice of varying or completely bypassing the
tone control section of the T 748. If “O” is selected, the Tone Control circuits
are active.
Select “On” to bypass the Tone Controls eectively defeating the eect of
the tone control circuits.
ZONE 2 CONTROLS
The Zone feature allows one to simultaneously experience in a dierent
zone of the house selected audio from any of the enabled Sources as well
as from iPod, Front, MP and Tuner.
Select “On” to activate Zone 2. When activated, the Source input for Zone
2 can be allocated by selecting through the following inputs – All enabled
Sources, iPod, Front, MP and Tuner.
As long as the associated Source input is active, it will continuously be
available at ZONE 2 output port in the rear panel regardless of the Main
Zone settings. For example, while the T 748 is at Source 1 mode, you can
set the Zone 2 Controls’ “Source” item to “Source 3”; the active Source 3’s
audio output will be directed to ZONE 2 output port in the rear panel even
though the T 748 is at Source 1 mode.
You can then feed the ZONE 2 jacks to another amplier or receiver
that maybe located in another area of your home or building. With your
separate amplier or receiver selecting the fed signal and with speakers
connected, you can then enjoy the zone selected source’s audio signal.
Adjust the volume control of your amplier or receiver according to desired
audio level.
If a Zone 2 is set to “O”, it is deactivated or powered o.
ZONE 2 AT AUDIO PREOUT SURROUND BACK
SURR-BACK L and SURR-BACK R channels of AUDIO PRE-OUT can be
assigned as Zone 2 OUT. This is applicable only if “Zone 2” is the selected
setting of “Back Amp” in the “Amplier Setup” menu.
With this condition, the following are applicable
• The surround back amplier channels supply Zone 2 speaker level
output via the surround back speaker terminals. With this setup, Zone
2 audio/speaker level can be increased or decreased using the VOL
(Volume) keys of the supplied ZR 7 zone remote control.
• At the same time, Zone 2 (item 6 “ZONE 2” in the “IDENTIFICATION OF
CONTROLS” section) continues to send zone selected audio source
to the corresponding audio input of a separately located additional
amplier or receiver (not supplied) that can power its matching set of
speakers. Zone 2 audio level for this port is xed; it cannot be adjusted
by any ZR 7 volume command.
• On the other hand, the secondary Zone 2 at AUDIO PRE-OUT (item
13 “AUDIO PRE-OUT/ZONE 2” in the “IDENTIFICATION OF CONTROLS”
section) also sends zone selected audio source to the corresponding
audio input of a separately located additional amplier or receiver (not
supplied) that can power its matching set of speakers. Zone 2 audio
output for this secondary Zone 2 can be increased or decreased using
the VOL (Volume) keys of the supplied ZR 7 zone remote control.
• For the applicable Zone 2 function, Zone 2 audio level can only be
adjusted using the Volume keys of ZR 7 remote control only if “Back
Amp” in the “Amplier Setup” menu is set to “Zone 2”. Setting “Back
Amp” to “Main Front” or “Main Back” will not allow Zone 2 audio level
adjustment.
IMPORTANT NOTICE
Only analog audio connected through a Source’s analog audio input
port can be associated as audio source for Zone 2. Digital audio sources
connected via HDMI, digital optical and digital coaxial input ports
cannot be downmixed and used as Zone 2 audio source.
