Amplifier Accessory Board Connection Instructions

Introduction:

This instruction shows you how to connect the accessory board to external audio

equipment, so please read all of this introductory material.

You should save these instructions for future reference. Many different connection

schemes are possible, and additional options and configurations can be added to existing

connections.

If you want to use the accessory board in a configuration that is not described, or if you

have difficulty installing one of the configurations, refer to the accessory board block

diagram (Figure 13), schematic diagram (Figure 14), and the installation tips and tech-

niques at the end of this installation instruction.

IMPORTANT: FOR PAGING AND MICROPHONE CAPABILITY YOU

WILL NEED KIT KOV-106-000-06, -09 OR -10. (SEE PAGE 35 OF

YOUR MOD BOX OWNERS MANUAL.)

Preparation

Before you begin, study the configuration that you wish to use to determine which

jumpers and audio cables will be needed to complete the installation (external cables for

connecting from the accessory board to other equipment must be purchased or as-

sembled).

When you have obtained all of the cables, continue with the installation.

External Connections

You are now prepared to connect the external devices. There are 4 different and

independent types of connections possible. You can connect:

•up to 2 microphones

•an external preamplifier (used for tone and volume control for the entire system)

•an external music source

•a separate external amplifier

The following paragraphs, along with the accessory board block diagram (Figure 3) and

schematic diagram (Figure 4), describe these connections.

PAGING MICROPHONE CONNECTIONS

The MoD BoX Paging Kit (part #KOV-106-000-06) is available through your local

authorized dealer.

2 Microphones

Plug the 5-way header of the first EC1918-01 microphone cable (part of MoD BoX Paging

Kit) into the microphone input header on the preamplifier. (This is a piggyback connection.)

Plug the 5-way header of the EC1918-01 microphone cable for the second microphone

into P3 of the amplifier accessory board.

1 Microphone

Plug the 5-way header of the EC1918-01 microphone cable into P3 of the amplifier

accessory board.

External Preamplifier

Use this configuration if you want the volume and tone of the entire jukebox sound system

to be controlled by an external preamplifier. This configuration uses the AVC portion of the

jukebox’s preamp, but bypasses its tone and volume controls.

Instructions

Cables and Jumpers

Obtain four shielded audio cables long enough to reach between the external preamp and

the amplifier accessory board.

This configuration requires only one of the three jumpers supplied with the accessory

board. Connect this jumper between:

1. J9 (LH CH INPUT) and J14 (INVERTER OUTPUT).

Input and Output Connections

Connect the input to the external preamp as follows:

1. Preamp RIGHT CH INPUT to J4 (RIGHT CH PREAMPAUX OUTPUT)

2. Preamp LEFT CH INPUT to J2 (LEFT CH PREAMPAUX OUTPUT)

Connect the external preamp output as follows:

1. External preamp RIGHT CH OUTPUT to J12 (RIGHT CH POWER AMP INPUT)

2. External preamp LEFT CH OUTPUT to J10 (INVERTER INPUT)

WARNING: Be sure that the equipment you are connecting to

the Jukebox has an isolation transformer type power supply.

Equipment that does not have an isolation transformer can

damage the jukebox and/or create a shock hazard.

Instructions

Cables and Jumpers

Obtain two shielded audio cables long enough to reach between the input device (FM radio,

TV, tape player, etc.) and the amplifier accessory board.

This configuration requires all three jumpers supplied with the accessory board. Connect

these jumpers between:

1. J9 (LEFT CH POWERAMP INPUT) and J14 (INVERTER OUTPUT).

2. J13 (RIGHT CH POWERAMP INPUT) and J20 (RIGHT CH PREAMP OUTPUT).

3. J11 (INVERTER INPUT) and J16 (LH CH OUTPUT).

Input Level Considerations

The background music input can accept a wide range of input levels. You can connect

speaker lines, aux. outputs or line outputs.

Stereo Background Music Input

Connect a stereo device as described here to provide background music from an external

source during periods that the jukebox is not playing a paid selection. The volume of this

music (generally lower than paid selections) is adjusted on the amplifier accessory board as

described on Page 9. The jukebox preamplifier settings are used for tone control. A device

connected to this input will not be heard during pages, or while the jukebox is playing a

selection.

WARNING: Be sure that the equipment you are connecting to

the Jukebox has an isolation transformer type power supply.

Equipment that does not have an isolation transformer can

damage the jukebox and/or create a shock hazard.

Input Connections

Connect the input cable from the music

source as follows:

1. RIGHT CHANNEL J8 (RH CH BGM)

2. LEFT CHANNEL J6 (LH CH BGM)

Mono Background Music Input

Connect a mono device as described here to provide background music from an external

source during periods that the jukebox is not playing a paid selection. The volume of this

music (generally lower than paid selections) is adjusted on the amplifier accessory board as

described on Page 9. The jukebox preamplifier settings are used for tone control. A device

connected to this input will not be heard during pages, or while the jukebox is playing a

Background Level and Switch-In Time Delay Adjustments

Background Level Adjustment

1. Select a song from the jukebox and make sure that the jukebox volume is at the desired

level.

2. Cancel the song, turn the SWITCH-IN TIME adjustment clockwise as far as it will go.

3. When the background music begins to play (in approximately 10 seconds), adjust the

BGM MUSIC LEVEL control for the desired background music level.

Switch-In Time Adjustment

The Switch-In Time can be adjusted from a minimum of approximately 10 seconds to a

maximum of approximately two minutes. To set this time:

1. Make another selection. While the song is playing, turn the SWITCH-IN TIME ADJUST

(see Figure 2) fully clockwise (it should already be in this position if you have just

finished the background music adjustment). Cancel the music. Approximately 10

seconds after the selection finishes, the background music will begin playing.

2. Turn the SWITCH-IN TIME ADJUST control counter clockwise slightly, play and cancel a

record, and note the switch-in time.

3. Repeat step 2 until the desired switch-in time is reached.

Instructions

IR Remote Kit

You must obtain and install Kit # KOV-106-000-07.

Cables and Jumpers

Obtain two shielded audio cables long enough to reach between the input device (FM radio,

TV, tape player, etc.) and the amplifier accessory board. Install an appropriate switch box

as illustrated below.

This configuration requires all three jumpers supplied with the Accessory Board.

Connect these jumpers between:

1. J9 (LEFT CH POWERAMP INPUT) and J14 (INVERTER OUTPUT).

2. J13 (RIGHT CH POWERAMP INPUT) and J20 (RIGHT CH PREAMP OUTPUT).

3. J11 (INVERTER INPUT) and J16 (LH CH OUTPUT).

Connect the input cable

from the music source

as follows:

1. RIGHT CHANNEL J5

(RIGHT CH AUX IN)

2. LEFT CHANNEL J1

FIGURE 8 - STEREO AUXILIARY MUSIC CONNECTIONS

WARNING: Be sure that the equipment you are connecting to

the Jukebox has an isolation transformer type power supply.

Equipment that does not have an isolation transformer can

damage the jukebox and/or create a shock hazard.

Stereo Auxiliary Music Input

You can connect a stereo device as described here, but you must suspend normal jukebox

operation while playing from this source. To do this, you must use the “Power” button on the

optional MoD BoX Infrared Remote Control. This will suspend jukebox operation while play-

ing the external source through the MoD BoX Amplifier and speakers (jukebox selections will

remain in queue and will resume when the “Power” button is pressed again). The jukebox

tone and volume controls will be used for this source as well as when the jukebox is playing

normally. Quick-disconnect or switching means should be included so that the external

source can be disconnected when restoring normal jukebox operation to prevent both

music programs from being fed to the amplifier simultaneously.
