Monoprice 5-Channel Commercial Audio Mixer Amp - 240 Watt, Black

The 240W 5-channel 100/70V Mixer Amp with Microphone Priority (NO LOGO) is designed to simplify the task of managing distributed audio in large venues such as restaurants, hotels, and other areas where background music and paging systems are needed. This amp allows you to connect hundreds of speakers across vast areas without the need for large equipment racks.

A constant voltage speaker system, as used in this amplifier, utilizes a step-up transformer at the audio source to increase voltage and reduce current on the transmission line. At the speaker end, a step-down transformer converts the signal back to a normal speaker level voltage. This setup reduces power loss during transmission, enabling longer speaker wire runs using smaller gauge wire.

In addition, a constant voltage speaker system allows for the use of multiple speakers on each channel without the complexity of impedance calculations. In this system, all speakers on a given channel are connected in parallel, simplifying the process. This contrasts with traditional speaker systems, where impedance calculations are essential and can impact the overall volume levels and performance of the amplifier.

This versatile amplifier features three microphone inputs and two auxiliary inputs, all mixed into the line and speaker level outputs. An EMC input trigger mutes all outputs except MIC 1 for important announcements. The amplifier can drive a speaker array with a 4~16 ohm load or 70V/100V speakers in parallel as part of a large public address system.

Key Features: - 5-channel mixer/amplifier with 240 watts rating - Options for 70V, 100V, and low impedance 4~16 ohm speaker outputs - Built-in rack mount ears for easy installation in a standard 19" equipment rack - Multiple input options including XLR, TRS, and RCA inputs - Dedicated controls for bass, treble, and volume adjustments - Variable muting for all channels except MIC 1 during microphone use - Built-in protection circuits for short circuit, over-current, and high temperature situations - Line level output for connecting to external devices

Overall, this rackmountable audio control center provides flexibility for large facilities and restaurants requiring distributed sound systems. The various input options and dedicated controls make it easy to customize the sound for any environment, while the EMC emergency killswitch ensures clear communication for important announcements and safety instructions.
