OPERATION
USING THE T 758 - MAIN MENU

DSP OPTIONS

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 758 has two Tone Control levels – Treble and Bass. Bass and Treble
controls only affect the low bass and high treble leaving the critical
midrange frequencies free of coloration.
These controls allow one to tweak on-the-fly, 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 758. If "Off" ("Tone Active" in the VFD) is
selected, the Tone Control circuits are active.
Select "On" ("Tone Defeat" in the VFD) to bypass the Tone Controls effectively
defeating the effect of the tone control circuits.
NOTE
Tone Controls options can be directly selected or changed using AVR 4's
[TONE] button with DEVICE SELECTOR set to AMP mode. Toggle [TONE]
button to select "Treble" or "Bass" and then use the [D/F] to adjust their
respective levels. Press [TONE] again to save the settings and at the same
time move on to the next parameter or exit the parameter setting altogether.

ZONE CONTROLS

Depending on the settings made at the separate "Zone Setup" menu
under the "Setup Menu" section discussion, Zone 2 can be configured and
managed via this "Zone Controls" window.
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, Front Input, Media Player, Tuner and Local.
18
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 758 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 758 is at Source 1 mode.
You can then feed the ZONE 2 jacks to another amplifier or receiver
that maybe located in another area of your home or building. With your
separate amplifier or receiver selecting the fed signal and with speakers
connected, you can then enjoy the zone selected source's audio signal.
Select "Local" as your selected Zone 2 Source input if you wish to enjoy the
same source as the main Zone and allow simultaneous listening, but with
full separate volume levels.
If a Zone 2 is set to "Off", it is deactivated or powered off.
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 "Amplifier Setup" menu.
With this condition, the following are applicable
•
The surround back amplifier 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 15 "ZONE 2" in the "IDENTIFICATION OF
CONTROLS – REAR PANEL" section) continues to send zone selected
audio source to the corresponding audio input of a separately located
additional amplifier or receiver (not supplied) that can power its
matching set of speakers. Zone 2 audio level for this port is fixed; it
cannot be adjusted by any ZR 7 volume command.
•
On the other hand, the secondary Zone 2 at AUDIO PRE-OUT (item
14 "AUDIO PRE-OUT/ZONE 2" in the "IDENTIFICATION OF CONTROLS
– REAR PANEL" section) also sends zone selected audio source to the
corresponding audio input of a separately located additional amplifier
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
"Amplifier 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. Ensure also
that the associated Source's Digital Audio setting is set to "Off" or no
actual digital source is connected.
