10.0 av2 operation
With appropriate inputs and outputs connected, and both Speaker and Input Setup
routines complete, the av2 is ready for use. If a setup parameter needs adjustment the
setup pages are always available from the remote handset or front panel as described in
Section 9. Remember however that some speaker setup parameters are subordinate to the
selected input and decode selection. For example, if an analog input and stereo direct
mode are chosen, only the main left and right speaker parameters will be available for
adjustment.
10.1 input selection and volume control
To select an input use the input key followed by one of the numeric keypad numbers 1 to
0 (front panel: input button). The keypad numbers correspond to the input socket numbers.
The handset i/p and i/p
input is selected the av2 display will sequentially show the input source (previously
specified in the Input Setup page) and the current decode mode settings. The default
display data is overall volume.
More! The av2 may take a moment to display inputs and decode modes when
new inputs are selected as it locks on to, and identifies, any signals. During this
time the display will show three flashing bars.
To adjust the overall volume use the vol
10.2 decode modes - selection and availability
The signal decoding behaviour and options of the av2 are dependent on both the source
programme material and in some cases the speaker setup previously specified. With
analog, and some digital programme material, decoding options are user definable -
although the results of processing for example, music material with movie decoding mode
are unpredictable. In some cases however the av2 will automatically identify encoded
material and only make available the appropriate decoding option or options. The av2
display and decode indicators together show each decoding mode selected or imposed.
To select a decoding mode use the mode key (front panel: mode button) followed by one
of the numeric keypad numbers. The keypad numbers correspond to decoding modes with
lower numbers selecting less complex modes (keypad 0 generally selects direct or auto
modes, keypad 1 selects mono, keypad 2 selects stereo, etc) The handset mode
mode can also be used to scroll through the available decode modes. The selected
decode option will flash in the display until the av2 has successfully "locked" to the signal
before the display reverts back to indicating volume. The av2 will store the last selected
decode mode for each type of signal and for each input. The decoding options and display
for each type of programme material, and the speaker channel schemes for each are
detailed in tables 10.4 and 10.5.
10.3 channel schemes and speakers
Channel schemes describe the speakers employed by each decode mode. They are
expressed by terms such as "5.1" or "3/2.1" Taking 5.1 as an example, the "5" refers to the
number of conventional speaker channels and the ".1" refers to a sub-woofer. In 3/2.1 the
"3" refers to the number of front channels employed (in this case, left, right and centre),
the "2" refers to the number of surround channels and the ".1" refers to a sub-woofer.
With appropriately encoded digital programme material channel schemes are displayed by
the av2 when decode modes and inputs are selected (if a signal is present).
