Description
The Behringer Eurocom MA4008 Installed Sound Multi-Function Mixing-Amplifier allows you to distribute audio and page listeners within two speaker zones. The unit consists of two Class-D mono amplifiers, one for high-performance low-impedance speakers and the other for 70- or 100-volt speakers. It features eight channels of mic/line inputs on Euroblock connectors with switchable phantom power, individual trim pots, and post-trim LED level indicators. In parallel, the device also includes four switchable microphone XLR/line TRS combination jacks with phantom power switches, and four dual summed to mono RCA jacks for sources such as MP3 players and TV tuners.
In addition to the two main outputs, the mixer-amplifier also includes a pre-master main mix output for recording and a line-level send and receive loop for external effect processing. The unit is capable of up to 80 watts of output. The front panel features level controls for each input, as well as high and low equalization settings for adjusting the main mix output. The mixer-amplifier is designed for installed sound applications that require continuous operation, distributed music, and paging such as education, business, retail, fitness, and hospitality.
Inputs For inputs, the unit includes eight mic/line inputs on Euroblock connectors with switchable phantom power, individual trim, and post-trim LED level indicators. It also features four balanced microphone/line XLR/TRS combination jacks with mic/line and phantom power switches, as well as four dual summed RCA jacks on channels 5 through 8. For announcements, you can connect a telephone or paging microphone to the device's dedicated 4-pin Euroblock paging inputs with priority muting and adjustable ducking of the other inputsControls The front panel of the device features a positive pressure power switch, level control knobs for each input, High and Low frequency equalization knobs for the main mix, an auto-dimming VU meter, and a dual-function power and clip LED indicator ring around the master volume control. For additional control, a wired remote with mute, volume, and power control may be wired to the amplifier's 5-pin Euroblock control connector
Power Supply The amplifier is powered by an efficient switch-mode power supply that conserves electricity and lowers the operating cost of the device
Protection Circuits For protection, the amplifier features individual DC and thermal overload protection circuits and electronic limiters to prevent distortion
