Preset Button

Pressing the Preset button once automatically selects the tuner, even if a different source

was already selected. It temporarily converts the knob from controlling volume to become

the Preset Selector for the stations that were stored into the 20 possible memory presets. Its

blue LED will stay lit for five seconds during which time the rotary knob is available for

selecting presets. If you want the knob to revert to volume control without waiting five

seconds, press the Preset button again.

Digital Button

Pressing the Digital button once temporarily converts the knob from controlling volume to

become the Digital Input Selector. Its blue LED will stay lit for five seconds during which

time you can choose any of the eight digital inputs, the 5.1 channel analog input, or return to

analog. If you want the knob to revert to volume control without waiting five seconds, press

the Digital button again.

Surround Button

Pressing the Surround button once temporarily converts the knob from controlling volume

to become the Surround Mode Selector. Its blue LED will stay lit for five seconds during

which time you can choose any of the five ASP modes. If you want the knob to revert to

volume control without waiting five seconds, press the Surround button again.

Surround Mode Indicators

These indicators let you know the type of digital bitstream the AVC-2500 has detected and

how it is being decoded.

DTS indicator

The blue DTS indicator illuminates when the AVC-2500 has detected a DTS bitstream,

regardless of which ASP mode you have selected.

Dolby Digital

The blue Dolby Digital indicator illuminates when the AVC-2500 has automatically detected

a Dolby Digital bitstream, regardless of which ASP mode you have selected.

Pro Logic Indicator

The blue Pro Logic indicator illuminates when the AVC-2500 has automatically detected an

analog, PCM, or 2/0 Dolby Digital signal. However, Pro Logic processing is only available

in the Cinema ASP mode.

Overload Indicator

The red Overload indicator will illuminate when any of the internal analog-to-digital

converters are being overloaded. This only occurs when an unusually high output analog

source is selected. The AVC-2500 monitors the extent and duration of the signal overload to

determine the optimum signal level applied to the A/D converters. If this indicator flashes,

the AVC-2500 will attenuate the signal just until the internal analog-to-digital converters

are no longer overdriven and the overload indicator stops flashing. This new level will remain

while the source is playing so there are not audible volume fluctuations. You can also manually

adjust the input level to the analog to digital converters in the setup menu.
