ยังไม่ได้ใช้ 773 นะครับ แต่เข้าใจว่าอาจจะเป็นเพราะใช้ software รุ่นเดิมอยู่ครับ เข้าใจว่าต้อง upgrade ผ่าน port RS232
ผมไป copy feature ใหม่ๆ ในคู่มือของ T773 มาให้อ่านกันดังนี้
Dolby Digital Pro Logic IIx (page 23)
Dolby Pro Logic IIx (page 24)
Dolby Digital Pro Logic IIx and Dolby Prologic IIx processes both stereo and 5.1 signals into a 6.1*- or 7.1-
channel output. For both Pro Logic IIx processes you can choose Movie or Music modes to tailor your listening
experience to source material. For two channel signals Pro Logic IIx Music mode also features three
additional user controls; Dimension, Center Width, and Panorama.
Setup Menus
Since the T 773 was introduced, we have been asked for more flexible options in the Setup Menus. This
resulted in adding a more ergonomic interface and new options such as a menu for the Zone settings.
Zone Settings (page 17 Advanced Options)
POWER STATE
There are two settings to allow the second zone to power on or off from the HTR 2 remote control instead
of using the ZR 2 remote control. With the HTR 2; toggling the POWER STATE to ON will power on the second
zone as indicated in the T 773s VFD, toggling the POWER STATE to OFF will power off the second zone.
VOLUME CTRL
There are now two primary settings for the second zone volume control; FIXED and VARIABLE. When set to
VARIABLE the second zone volume will be adjustable via the ZR 2. When set to FIXED the second zone
volume will be set to the preset level as shown on the ZONE SETTINGS, LEVEL. The FIXED setting is the
preferred setting when the second zone amplifier has its own volume control (or when using a distribution
amplifier with passive impedance matching volume controls).
LEVEL (page 12 MS OUT)
This sets the audio volume level at initial power on of the second zone MS OUT (MultiSource Out). Set this
level from -75dB to +18dB (the default setting is -20dB). To change this level the VOLUME CTRL setting must
be set to VARIABLE. Once the VOLUME CTRL setting is set to FIXED, the level cannot be adjusted. To mute
the MS OUT; press ENTER on the HTR 2 and an M will show beside the audio volume level to indicate
muting.
AUTO TRIG IN
This feature was formerly named AUTO TRIGGER, and still functions as it did before.
ZONE SPEAKER
The internal amplifiers can be used by the MS OUT, either all or some of SPEAKERS A or SPEAKERS B. Assign
either speaker set to be active when the second zone powers on. The settings for ZONE SPEAKER are;
SPEAKER A, SPEAKER B and NONE.
Note: Using this feature requires that the Pre-Out/Main-In jumper be removed and the MS Out be connected
to the Main-In of the desired channels using RCA to RCA cables (not supplied). To access the Speaker A
+ B feature, the Front L + R amplifier channels should be used. The Front L +R Pre-Out should then be
connected to the Surround Back L + R Amp-In jacks with the main zone front speakers attached to these
speaker outputs. Obviously, any amplifier channels used for second zone will no longer be available in the
main zone. This does allow the 7 channel T 773 to operate a 5.1 surround system in the main zone and a
simultaneous independent stereo feed to a second remote zone.
Advanced Options (page 17)
Dolby Digital Pro Logic IIx is now a surround mode selection available by the HTR 2s and T 773s front panel
button, SURROUND MODE.
Speaker Settings (page 16)
ENHANCED BASS
When the subwoofer is set to ON and one or more speakers are set to LARGE, ENHANCED BASS is also
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 effects, the bass response may be uneven when using this setting.
Input Settings (page 15)
The option to rename inputs is now available. Press the ENTER button to select the renaming menu. The
name can be as long as thirteen characters. Use the HTR 2s navigation buttons to select the appropriate
letter and then press ENTER.
For each input, any or all signals can now be set to OFF, including: VIDEO IN, ANALOG IN, and DIGITAL IN.
This is desirable if the signal source is not connected to the selected input.
Trigger outs TRIG OUT 1 and 2 also can also be set to OFF for any input.
ANALOG IN GAIN is now adjustable from -12dB to +12dB allowing adjustment to prevent large shifts in
volume when changing inputs. It is preferable to reduce the volume of the loudest inputs to match the
softest inputs rather than the other way round.
TRIG OUT 1 and 2
The menu for setting for trigger out is now on the same page as INPUT SETTINGS. Thus trigger out 1 and
2 may be set independent of either main or zone power on state for each input.
Save To Preset (page 18)
The option to rename all five A/V Presets is now available. The preset settings must be stored first before
renaming. Store the preset by using the HTR 2s navigation buttons and then press the ENTER button. Press
the navigation button to toggle through to the NAME? menu then press the HTR 2s ENTER button a
second time. The name can be as long as thirteen characters. Use the HTR 2s navigation buttons to find
the appropriate letter and then press ENTER to select.
Enhanced User Features
A/V Presets for Speaker Configuration (Quick Setup)
Five of the most common speaker setups are pre-configured to simplify first time use of your new surround
sound receiver. Select your speaker configuration from the table below, and use the A/V Presets to select
the most appropriate one. Your selection may be fine tuned by following the instructions for SPEAKER
SETTING (page 16).
Listening to Radio (page 19)
RDS TEXT
RDS TEXT will now display on the T 773s OSD below the stations number and name. RDS TEXT will scroll
across the OSD as well as the T 773s VFD.
HTR 2 Direct Frequency Entry
With the HTR 2 you can now directly enter the frequency of the radio station. When entering digits, more
than three will force the direct entry mode. Pressing ENTER will lock the frequency as seen on the T 773s
VFD and OSD. For example; pressing 1021 will force the direct entry to 102.1.
Sleep Mode
The Sleep Mode timer will switch the T 773 to Standby mode automatically after a preset number of minutes.
Pressing the HTR-2s SLEEP button once will display the setting of the sleep time increment. Pressing the
HTR-2s SLEEP button a second time within a 3-second period will change the sleep time increment in 15-
minute intervals, after which time the T 773 will automatically switch into Standby mode. The sleep time
increment will display on the T 773s front panel Vacuum Fluorescent Display (VFD) as well as an icon
SLEEP that will display continuously in the top left corner of the T 773s front panel VFD.
To adjust the sleep delay, press the HTR-2s SLEEP button twice; first to display the sleep time increment,
and a second time to change the sleep time increment. Each consecutive press increases the sleep time in
15-minute increments from 15 to 90 minutes. To cancel the sleep mode, continue pressing the HTR-2s
SLEEP button until SLEEP OFF displays on the VFD. Switching the T 773 to standby from either the HTR-
2s OFF or the T 773s POWER button will also cancel the sleep mode.
