Volume Control Unit
The Volume Control Unit (VCU) shown in Figure 3-5 , is a Rowelink module and should be
mounted remotely (behind bar, etc.). A plate is supplied in the Handy Pack to cover the hole
if the VCU is removed. Use the VCU screws to secure the plate. It displays and controls the
volume of the amplifier channels and microphones. If an existing 100 foot cable is already in
place, you can use the 3-wire or 4-wire (see
Figure 3-6) alternate wiring.
•
The POWER button turns the Grand STAR Jukebox lights, touch-screen monitor and Bill
Acceptor ON or OFF.
•
The REJECT button rejects the selection playing.
•
The FUTURE button adds credits toward selections (See “Credit Management” in the
Operator Setup Screens Manual).
• The MODE key toggles between channels and microphones.
•
The VCU also raises or lowers the volume of the channel(s) or microphone using the UP
DOWN keys. The volume range is 0 to 63. Channel Volume is displayed when the
mode LED is off, and microphone volume is displayed when the mode LED is on.
The CH, MIC, and SINGER LEDs indicate what volume is being displayed when toggled
by the Mode Switch. When adjusting channel volume, if more than one LED is on, it
means those channels have the same volume. All four channels have the same volume
when shipped from the factory (see
Section 3 of the included “Network Setup, Jukebox
Operation, Operator Setup Screens” manual for other possible configurations).
4 Channel Preamplifier
This Rowelink module transforms audio signals from the Core Computer, microphones, and
other sound processors/equipment/systems into signals for the Power Amplifier. It also
contains Automatic Volume Control (AVC) to adjust for varying recording levels and tone
controls via 5-band equalizers. All adjustments and options are programmable via the
touch-screen and are retained on the Core Computer hard drive (see
Section 3 of the
included “Network Setup, Jukebox Operation, Operator Setup Screens” manual for setup
information).
1000-Watt Audio Digital Power Amplifier
The 2-channel digital audio power amplifier is rated 1000 watts RMS (500 per channel) into
a 2-ohm load. The full volume output voltage is 32 volts.
The amplifier is protected against overloads and short circuits. Continuous severe
overloads or shorts may shut down the amplifier (or a channel) but will not damage it. If the
overload is removed a signal will reset the amplifier when the next selection plays.
Audio Output Transformers
The output transformers “step up” the power amplifiers output voltage for 70-volt extension
speakers. They also provide screw connections for selecting different power levels for
extension speakers.
