Amplifier Description

Rock-Ola’s Dual Digital SyberSonic Amplifier has been

engineered for ease of connection and has options to meet

virtually any location requirement. With audio efficiencies

approaching 95%, this system produces volume levels equal

to an amplifier twice its size and does so without producing

a great amount of heat.

The system consists of a dual stereo (4 channel) pre-

amplifier combined with two 2-channel power amplifiers.

One output is designated as “Internal Output”, the other is

designated “External Output”.

The system may be operated as a single zone or a dual zone

stereo system with separate volume controls for each zone.

The internal output sends its power to an Audio Output

Panel that couples the console speakers along with extension

speaker loads of ½ to 8 ohms. The external output sends

its power to an Audio Output Panel that couples speaker

loads of 1/8 to 8 ohms.

Additionally, the External Output Audio Panel provides a

connection for stereo or mono 70-volt CV speakers.

Please Note: This section mentions Internal and External

Amplifiers. With the factory default amplifier and volume

control settings, “Internal” refers to the two channels con-

trolled by the “INT” volume buttons and normally con-

nected to the jukebox speakers. “External” refers to the 2

channels controlled by the “EXT” volume buttons used for

external speakers. If the optional Multi-Zone Volume Con-

trol is used, or you wish to assign your own zones, the out-

puts are designated:

Internal Left = Channel 1

Internal Right = Channel 2

External Left = Channel 3

External Right = Channel 4

Plug-in RCA Type Connectors for:

AUX BGM - Input with automatic switching and pro-

grammable minimum/maximum volume settings.

Fixed Output - line level output directly from the core.

Int/Ext Output - 4 channel pre-amp outputs. Signal

level is variable with volume control settings.

Indicator LED’s

The Digital SyberSonic Amplifier has LED’s to give a vis-

ual indication of its operating condition and status. The

LED’s and their functions are as follows:

Power - When lit, indicates the amplifier has power.

Status - Indicates when the paging system (micro-

phone) is active.

Steady On - Normal operation. Paging system is avail-

able.

Flashing - Paging system is in use.

COM - Indicates when amplifier receives instructions from

the jukeboxes Core unit.

Always Off - Indicates a communication fault between

the amplifier and Core Unit.

Single One Second Flash on Power Up - Processor is

running.

Steady On - Normal operation. Setup instructions re-

ceived and installed.

Intermittent Flashing - Amplifier is receiving instruc-

tions from Jukebox Core Unit.

Overload - When lit, indicates the amp is muted or a

speaker overload condition exists.

Signal Inputs and Outputs

The Digital SyberSonic Amplifier has five (5) sets of RCA

type jacks located at its upper right corner.

Figure 2D – RCA Jacks

Each set of connectors have separate functions, they are:

CD In - This connection is the analog audio signal that is

being fed directly from the Core unit Audio Output into the

amplifier.

Fixed Out - This connection is the unconditioned analog

audio output from the Core unit.

BGM In - This connection allows the input of a low level

signal (maximum 1 volt RMS) from another audio source

(such as a tape player, TV or FM tuner) to be fed into the

amplifier for aux background music amplification. The sig-

nal volume level is limited via software setting Set Back-

ground Music Play Levels.

Note: This amplifier is designed to automatically switch

between the AUX BGM and CD inputs where the CD input

always takes priority.

WARNING Do not connect the AUX BGM Inputs

to the speaker outputs of a receiver or

power amp as this will damage the

jukebox amplifier and void its war-

ranty.

Int Out - Left & Right - These connections are a variable

level output signal directly from the internal pre-amp. In the

default configuration, the signal level follows the internal

volume control. If the optional Multi-Zone Volume Control

is used, channels 1 and 2 control these signal levels respec-

tively. Output signal level may be limited via software con-

trol in Amplifier Output Volume and Limits.

Ext Out - Left & Right - These connections are a variable

level output signal directly from the external pre-amp. In the

default configuration, the signal level follows the external

volume control. If the optional Multi-Zone Volume Control

is used, channels 3 and 4 control these signal levels respec-

tively. Output signal level may be limited via software con-

trol in Amplifier Output Volume and Limits.

Amplifier Feature Descriptions

Your Digital SyberSonic Amplifier is preset at the factory

for optimum operation; however some adjustment may be

required to achieve the best sound or operating features for

your particular environment. For ease of use, amplifier fea-

tures are set or adjusted via the jukeboxes touch screen.

Setting Instructions are found in the section titled “Set-

ting the Amplifier” later in this chapter.

AVC Control - The Digital SyberSonic Amplifier uses

software to limit the difference between loud and soft re-

cordings (dynamic range). Automatic Volume Control

(AVC) will retain the dynamic range of the recording, just

reduce it. The effect is that the music sounds natural but

songs with loud passages are only slightly louder. AVC also

controls the BGM IN signal. Note: This feature may not be

turned off.

Equalizer – This changes speaker tone by decreasing the

response (gain) of a particular frequency range. Each of the

4 possible zones/channels may have separate settings.

Balance – Set the channel balance by increasing or decreas-

ing its volume level, as compared to the other, then link one

channel to the other. See Setting The Amplifier for Instruc-

tions

Music Level While Paging (MLWP) - Mic and Paging

Parameters – This setting changes how much of the music

is heard when using a microphone for paging while music is

playing. Each channel has separate settings. The music level

is a percentage of the current volume. Choices are 0% to

100% in increments of 10% and On or Off where Off de-

feats paging for that channel.

Loudness – This setting allows you to turn on or off the

loudness contour enhancement for the each channel sepa-

rately. The Loudness Contour enhances bass output at lower

volume levels.

Volume Limits – The Digital SyberSonic amplifiers can

have their volumes set to minimum and maximum levels.

Each channel may be set separately in both Normal Play and

Background Music Modes.

Volume Control (zone) Linking – There may be times

when you do not want a location to have separate control of

the internal and external amplifier. Or perhaps you want two

or more areas to have separate volume controls. Syber-

Sonic’s advanced electronics system allows the “linking” of

its volume controls.

When linked, pressing either the Internal or External buttons

will the cause the linked channels volume to change. Also

when linked, the system will maintain the set balance, thus

eliminating the need to “tap” the speakers. Setting informa-

tion is in the “Setting The Amplifier” section.

Setting The Amplifier

The graphic equalizer, channel volume linkages, and other

features are adjusted via the jukebox touch screen with set-

tings represented by a graphic.

Section E of this manual contains specific instructions for

accessing and using the Service Console. The following

section will only give instructions for items that pertain to

the audio system.

To set the amplifier features, access the Service Console by

opening the dome or, if the dome is already opened, cycle

the Service Switch. The following screen will appear:

Fig. 3D

Touch System Settings and Diagnostics >

Fig. 4D

Touch Configure Audio Amplifier >

Fig. 5D

Touch the desired feature then “program the amp” in the

same way that all other programming is done. To exit a

screen, touch the Back button. To completely exit the Ser-

vice Console, touch the Quit button.

For brevity, this section will assume the Service Console >

System Settings and Diagnostics screens have already

been accessed, therefore the instructions will show the touch

steps as Configure Audio Amplifier > desired feature>

setting.

Hint: Because these settings affect the sound, it is best to

play a few songs before accessing the Service Console so

that music will be playing and you can hear the changes.

Configure Paid Selection Volume

This screen is used to link channels to create zones and set

the Minimum, Current and Maximum Volumes for Paid

Selections. Touch Configure Audio Amplifier > Config-

ure Paid Selection Volume.

Fig. 6D

Set Paid Output Volume and Linkage – This sets the cur-

rent volume level, channel balance and volume zones.

Set Paid Output Volume Limits – This sets the Minimum

and Maximum allowable volume for each channel.

To set the current Paid Selection Volume or to assign

zones, touch Configure Audio Amplifier > Configure

Paid Selection Volume > Set Paid Output Volume and

Linkage.

Fig. 7D

To assign volume zones, you will link or unlink channels.

The Zone indicator will change automatically as you link or

unlink channels. The screen above shows the default, 2-zone

settings as used with the RF, IR and red (6 button) wired

volume control.

Internal Right Output = Channel 1

Internal Left Output = Channel 2

External Right Output = Channel 3

External Left Output = Channel 4

Hint: Before creating zones, unlink all channels, play a

song and set each channels volume so that the jukebox

and extension speakers are “balanced” to your liking.

Then link the desired channels to create your zones.

In this configuration, Channels 1&2 are linked to create

Zone 1 and Channels 3&4 are linked to create Zone 2.

When the INT volume buttons are pressed, Channels 1&2

(Internal L&R) change together. When the EXT volume

buttons are pressed, Channels 3&4 (External L&R) change

together. You may reassign which zone the INT and EXT

buttons control in the Two Channel Zone Assignments

Screen.

Several other installation scenarios are shown in Section C

of this manual.
