Owner's Manual

SPEAKER CONFIGURATION
Every surround-sound system requires “bass-management” to direct low-
frequency content from any or all channels to the speakers best able to
reproduce it. For this function to operate correctly, it is important that you
correctly identify your speakers’ capabilities. We use the terms “Small” and
“Large” (and “O”) but note that physical size may be irrelevant.
• A "Small" speaker is any model, regardless of physical size, that lacks
signicant deep-bass response, that is, below about 200 Hz.
• A "Large" speaker is any full-range model; that is, one with deep-bass
response
• An "O" speaker is one that is not present in your system. For example,
you might not have any surround-back speakers installed; in that case,
you would set the ‘Surround’ setup item to "O".
The Speaker Conguration is “global”; that is, it remains in force with all input
and listening modes. However, speaker settings are part of the T 777’s Preset
system. Consequently, multiple speaker settings can be stored for easy recall as
dierent types of recordings or listening modes require.
Speaker Conguration can be managed and adjusted by pressing a
combination of [S] and then [D/F] keys. Set “Front”, “Center” and
“Surround” to “Large”, “Small”(40Hz to 200Hz) or “O” as your subsystem’s
speakers require.
The “Back” speakers can either be one or two speakers. Set “Back” to either
1 or 2 speakers as per availability. Set “Subwoofer” to “On” or “O” selecting
“On” only if you have a subwoofer connected to the T 777’s SUBW1 or
SUBW2 output jack. If “Subwoofer” is set to “O”, “Front” speakers will
automatically be set to “Large”.
ENHANCED BASS
When the subwoofer is set to “On” and “Front” is set to “Large”, the option
“Enhanced Bass” becomes available. Normally, with speakers set to “Large”
the subwoofer is not active. The Enhanced Bass option allows full range
operation of the speakers with the additional bass contribution of the
subwoofer. This feature is particularly useful when one wants to experience
maximum bass output. Please note that due to acoustic cancellation
eects, the bass response may be uneven when using this setting
You can set Subwoofer to “On” even with “Large” front speakers, in which
case bass content from any channels set to “Small” will be routed to both
the subwoofer and to the front speakers; LFE-channel signal will pass only
to the sub. In most subwoofer-equipped systems, setting front speakers to
“Small” is usually the better option.
All the speakers’ low frequency content can be directly adjusted within the
range 40Hz to 200Hz.
NOTE
The congurations set forth at ‘Speaker Setup’ are carried over whenever
it is enabled during A/V Preset setting. Please see also the section ‘AV
Presets’ for reference.
SPEAKER LEVELS
Adjusting the relative balance of your system’s loudspeakers ensures that
surround-sound recordings, whether music or lm, will present the balance of
eects, music, and dialog that the artists intended. Additionally, if your system
incorporates a subwoofer it establishes a correct relationship between the
volume of the subwoofer and the other speakers, and thus of low-frequencies
(bass) to other sonic elements.
USING AN SPL METER
It is quite practical to perform the T 777 level setup routines “by ear,” and
careful work will produce acceptably accurate results. However, the use
of an inexpensive sound-pressure level (SPL) meter, such as Radio Shack
part number 33-2050, makes this task easier, more accurate and more
repeatable. Ownership of such a meter could prove a valuable audio tool.
