Overview

MA-BT240 MIXING AMPLIFIER WITH EXTENDED BLUETOOTH

The MA-BT240 installation amplifier is your comprehensive mixing amplifier solution for smaller commercial applications. Combining high- and low-impedance amplification with a microphone input, line-level inputs, and built-in Bluetooth® for wireless audio streaming, the MA-BT240 is a versatile mixing amplifier for restaurants, retail stores, institutions, waiting rooms, and other small commercial spaces.

Features

• Installation amplifier with comprehensive I/O for small to mid-sized facilities
• Efficient Class D amplifier supports low-impedance (120W x 2ch @ 4Ω/8Ω) and high-impedance (240W x 1ch, 100V/70V) connections
• Equipped with Bluetooth® receiver for wireless music streaming from portable devices
• 2 Line inputs (RCA connectors)
• Mic/Line input with switchable Ducking/Paging function to automatically mute background music during announcements
• Built-in mixing with front-panel knobs for all inputs
• Compact half-rack design for convenient placement on desktop or shelf
• Bluetooth® antenna can extend allowing you to place it in the optimal position for your specific space
• 2-band EQ and high pass filter (recommended for high-impedance applications) on output allow you to fine-tune the system response
• Output can be optimized for any speaker configuration with Mono/Stereo switching (low-impedance mode)
• Master volume can be adjusted remotely from external controllers (sold separately)
• Line output allows you to create additional zones by cascading to other power amplifiers
• Can be rack mounted with optional AK-RM05 rack kit (sold separately)
