Commercial Paging System Accessory | Background Music Integration | Adjustable Bass, Treble & Volume | MC-60/4A Compatible

The Aiphone MC-A/A MarketCom Paging Adaptor is a professional-grade audio paging interface designed for use with the Aiphone MC-60/4A MarketCom Intercom System.

Engineered for commercial offices, retail stores, warehouses, industrial facilities, schools, and institutional buildings, the MC-A/A allows authorized personnel to broadcast announcements through a compatible external paging amplifier and speaker system.

Supporting MarketCom installations with up to 60 MC-60/4A handset stations, the adaptor provides a centralized paging connection while maintaining the system's four independent intercom communication channels.

The MC-A/A features separate volume, bass, and treble adjustments for paging and background music, allowing each audio source to be individually configured for the installation.

An integrated adjustable pre-page chime provides an audible notification before announcements, while the automatic music-muting function temporarily interrupts background music during paging.

Designed for integration with standard paging amplifiers, including compatible Aiphone MD Series equipment, the MC-A/A provides a practical solution for facilities requiring combined intercom communication, public-address announcements, and background music distribution.

Operating on 24V DC power, the adaptor features a compact metallic-gray housing, accessible audio controls, and an included mounting bracket for installation on a wall or compatible single-gang electrical box.

Paging & Audio Functions

1. Commercial Paging Integration

The MC-A/A interfaces the Aiphone MC-60/4A communication system with an external commercial paging amplifier.

Authorized personnel can initiate paging announcements from compatible MarketCom handset stations using the system's paging controls.

The adaptor transfers the paging audio to the connected amplifier, which distributes the announcement through the installed speaker system.

2. Background Music Distribution

A compatible external music source can be connected to the MC-A/A through its designated music input.

The adaptor passes the audio to the paging amplifier for distribution through connected speakers.

This provides a combined background music and paging arrangement without requiring separate music and announcement speaker systems.

3. Automatic Music Muting

When a paging announcement begins, the MC-A/A automatically interrupts the background music signal.

After paging concludes, the music can resume through the connected amplifier.

This helps ensure that announcements remain intelligible without competing background audio.

4. Independent Music & Paging Controls

The MC-A/A provides separate adjustment controls for its two audio functions.

Paging Controls:

• Volume

• Bass

• Treble

Background Music Controls:

• Volume

• Bass

• Treble

These adjustments allow installers to balance announcement clarity and background music levels independently.

5. Adjustable Pre-Page Tone

The integrated pre-page chime provides an audible signal before an announcement.

The chime volume can be adjusted to an appropriate level for the facility.

This is useful in commercial environments where employees or occupants need an audible indication before important announcements.

6. Up to 60 Intercom Stations

The MC-A/A supports the MarketCom architecture with up to 60 compatible MC-60/4A stations.

The system can be configured using six wiring blocks, with up to ten stations per block.

The paging adaptor works with the MarketCom system's separate paging function while maintaining the four selective intercom communication channels.

7. External Amplifier Connection

The MC-A/A provides a paging audio output for connection to an appropriate commercial paging amplifier.

Compatible Aiphone amplifiers include the MD35M, MD60M, and MD120M.

The required amplifier must be selected according to speaker load, cable arrangement, and facility coverage requirements.

Note: The MC-A/A does not contain a built-in power amplifier capable of directly operating a commercial paging speaker network.

Installation & Compatibility

The Aiphone MC-A/A is designed primarily for the Aiphone MC-60/4A MarketCom paging and communication system.

The adaptor receives compatible intercom paging signals and routes audio through a connected external amplifier.

A separate background music input allows an external music source to share the paging speaker system.

System Connection Overview

1. Connect the compatible MC-60/4A communication station wiring to the MC-A/A.

2. Connect the approved 24V DC power supply.

3. Connect the paging adaptor output to a compatible amplifier.

4. Connect an optional background music source.

5. Connect the amplifier to the appropriate commercial paging speakers.

6. Adjust paging volume, music volume, bass, treble, and pre-page tone settings.

7. Test communication, paging, and music muting.

Wiring Requirements

The MarketCom system uses seven-conductor intercom wiring with designated terminal assignments.

Aiphone specifies non-twisted, low-capacitance cable for the MarketCom station connections.

The cable must meet the manufacturer's conductor and capacitance requirements.

In the standard MarketCom configuration, the paging adaptor supports:

• Up to six handset wiring blocks

• Up to ten MC-60/4A stations per block

• A maximum of 60 handset stations

Manufacturer system diagrams provide wiring-distance limits based on conductor size and the total cable installed.

Mounting Options

Single-Gang Electrical Box

The included mounting bracket can be attached to a compatible single-gang electrical box.

Direct Surface Mount

The included bracket can also be attached to a suitable wall surface using the appropriate mounting screws.

The adaptor chassis locks onto the bracket after installation.
