Clever Acoustics ZM 4 4-Zone 5-Channel 3U Rack Mixer

£169.00 (inc. VAT)

The Clever Acoustics ZM 4 is a 4-zone mixer perfect for multi-zone audio systems where separate volume control & source selection is required.

The ZM 4 is great for restaurants, bars, pubs, and commercial environments that have multiple areas/rooms, and want to either control the volume separately or have a different source of music playing in each area.

Featuring four switchable Mic/Line inputs (XLR/Jack Combo), and one Line (Phono) designed for connecting smartphones, tablets, laptops, CD players, FM radios, and handheld/wireless microphone systems.

Each input has dedicated 3-band EQ (Gain, HF, LF), volume control, and independent routing to each of the 4 zonal outputs.

The Clever Acoustics ZM 4 has four Line Outs for taking off to a 4-channel slave/power amplifier, or 4 independent power amplifiers that are running an array of 100V/Low Impedance loudspeakers.

The ZM 4 also has a TEL Paging input, a priority input for music mute, and a Monitor Line Output.

Channel 1 is the priority input and will cut/mute any other inputs/audio playing. This makes it perfect for making PA announcements where you need only the sound of the microphone to come through. Using Channel 2 however will play over any audio from other inputs and will also dip the audio slightly making it perfect for pub quizzes, for example.

Supplied with a 3-year manufacturers warranty.
