1. ON: This pushbutton switches the unit on and off. The green LED next to the ON switch
lights to indicate the unit is ON.
2. DIGITAL: This pushbutton switch toggles between the analog and digital inputs. The green
LED next to the DIGITAL switch lights to indicate the digital input has been selected.
3. INPUT: This rotary control sets the level at the audio output.
Selecting the digital input disables the INPUT control.
4. INPUT LED: This bi-color LED indicates the signal level at the input to the audio circuitry:
flickering/lighting green indicates optimum level range, red indicates overload.
5. PHONES: 1/4" stereo jack for connecting a pair of hardwire stereo headphones.
6. VOLUME: This rotary control sets the volume of the headphones connected to the
PHONES jack (5).
7. SURROUND: This five-step rotary switch is located in the signal path between the input
stage and the MODE switch. It switches the Dolby decoders on and off or adds one of
three different reverb programs to normal stereo signals. The output signal of the
SURROUND selector passes through the MODE switch and on to the IVA or VMAx pro-
cessor or directly to the output.
AUTO: This mode automatically activates the Dolby Pro-Logic or Dolby Digital decoder
depending on whether a Pro-Logic or Dolby Digital signal is present at the input. One
green LED each will light to indicate which decoder is currently active.
If a normal stereo signal is present at the input, we recommend that you set the
SURROUND selector to "OFF" in order to avoid undesired sonic results.
OFF: Both Dolby decoders are out of circuit and the input signal passes to the MODE
selector (9) unchanged. The DOLBY DIGITAL and the PRO-LOGIC LEDs will extin-
guish.
CLUB, HALL, STADIUM: Acoustic simulations of three different venues of different
sizes.
8. STEREO: This green LED indicates the following modes:
Stereo signal at the input and SURROUND
selector (7) in "OFF" position:
SURROUND selector (7) in "CLUB",
"HALL", OR "STADIUM" position:
SURROUND selector (7) in "AUTO"
position:
MODE selector (9) in "DIRECT" position:
MODE selector (9) in "IVA-PHONES" or
"VMAx" position and SURROUND
selector (7) in "AUTO" position:
9. MODE: This three-step rotary switch selects the following modes:
IVA-PHONES: The IVA processor is active and affects the signal at the PHONES and
LINE outputs. In this mode, the green LED below the IVA-PHONES label will be
illuminated.
DIRECT: In this mode, all signal processors are out of circuit and all controls and indi-
cators to the right of the MODE selector are disabled. You will hear the unchanged
stereo input signal in the hardwire and wireless headphones and the loudspeakers
you may have connected to the HEARO 999 AUDIOSPHERE. The IVA-PHONES and
VMAx LEDs extinguish.
A Dolby Digital encoded signal present at the input will be automatically mixed down
to a Pro-Logic encoded stereo signal.
