output in order to synchronize it with the video image.
TONE CONTROLS
MAIN MENU
The Main Menu contains menu options for “DSP Options”, “Tone Controls”,
“Zone Controls”, “System Info” and access to “Setup Menu”.
Follow the guidelines about “DISPLAY THE OSD” and “NAVIGATING THE OSD
AND MAKING CHANGES” to navigate through the menu options and their
sub-menu selections.
NOTE
The individual congurations set forth at “DSP Options” and “Tone
Controls” are carried over whenever they are enabled at A/V Presets
setting. Refer also to the section about “A/V PRESETS”.
The T 778 has three Tone Control levels – Treble, Bass and Center Dialog.
Bass and Treble controls only aect the low bass and high treble leaving
the critical midrange frequencies free of coloration. The Center Dialog
(“Dialog” in the front panel display) control boosts the “presence” of the
midrange region improving intelligibility of speech.
These controls allow one to tweak on-the-y, the frequency response
of the source during playback. The control setting could be adjusted by

ZONE CONTROLS
Depending on the settings made at the separate “Zone Setup” menu
under the “Setup Menu” section discussion, Zone 2 can be congured and
managed via this “Zone Controls” window.
Set “Power” to “On” to activate Zone 2. When activated, the Source input for
Zone 2 can be allocated by selecting through the following inputs - Source
1, Source 2, Phono and Local.
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 778 is at Source 1 mode, you can
set the Zone 2 Controls’ “Source” item to “Source 2”; the active Source 2’s
audio output will be directed to ZONE 2 output port in the rear panel even
though the T 778 is at Source 1 mode.
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.
• BluOS audio is also not applicable as a Zone 2 audio source.
VOLUME
“Volume” refers to the adjustable secondary Zone 2 Volume level that can
be increased or decreased depending upon its settings. This is applicable
only if the Zone 2 Volume setting in the separate “Zone Setup” menu under
“Setup Menu” is set to “Variable”. If set to “Fixed”, this “Volume” item at
the Zone Controls section will not be available.
NOTES
• If Zone 2 is still ON and STANDBY button is pressed to switch the
front panel display to standby mode, the front panel display will be
extinguished but the STANDBY LED remains illuminated blue. This

You can then feed ZONE 2 output using applicable connector cables (not

area of your home. With your separate amplier 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 Zone 2 “Power” is set to “O”, it is deactivated or powered o.

• The surround back amplier 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 continues to send zone selected audio source
to the corresponding audio input of a separately located additional
amplier 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.
• Zone 2 audio level can only be adjusted using the Volume keys of ZR 7
remote control only if “Back Amplier” in the “Amplier Setup” menu is
