The MX155 is a 7-Channel mic/line mixer with 5 multi-purpose mic/line inputs, one dedicated microphone input and talk-over feature. All inputs feature EQ’s and Gain control. The balanced output is provided via Euroblock connector. Remote muting and emergency signal replay facilitate the use in installed sound systems. Features: 5 x Mic/Line Level Inputs (Euro/RCA) 1 x Slave FOH or AUX Input (Stereo TRS or 3.5mm Stereo Jack) 1 x Dedicated Mic Input w/VOX Feature (Euro Con) Headphone Pre-Fade Monitor Jack Stereo REC Output (RCA) Stereo Balanced Output (Euro Con) Emergency Line Level Input Music Mute Contact (NO only) The mixer has five primary channels, each of which has a balanced mic input and an unbalanced stereo line input: all connections are on the rear panel. There is a further stereo auxiliary line input, with both a balanced rear panel input and an unbalanced 3.5 mm TRS jack on the front panel allowing easy connection of tablets, laptops, etc. An additional, independent mic input channel is also routed to the main output; this channel features adjustable VOX detection to allow paging use, with voice-over-programme ducking. VOX threshold is adjustable via a rear panel preset control and the depth of ducking adjustable from the front panel. The front panel provides level and HF/LF EQ controls for each of the five main channels and the mic channel; a level control for the auxiliary line input is also fitted. 15 V phantom power is available at all mic inputs, selected by internal jumpers. The stereo output of the mixer is balanced: the front panel has an output level control and an LED bargraph meter. A rear panel switch converts the output for mono operation. Headphone monitoring of the main output is available on the front panel, with an independent headphone volume control. Installers can set the maximum level of the main output via a rear panel preset control, to prevent inadvertent overloading of power amplifiers or damage to loudspeakers. The mixer has an additional unbalanced stereo line output carrying the main mix: VOX ducking affects this output, but the level is independent of the master output level control. To aid compliance with PA-VA regulations, the MX155 has a dedicated emergency input (balanced): when a signal is detected at this input, all other inputs are muted and the emergency input routed directly to the mixer output. An internal jumper determines whether the mic channel should remain unmuted in this situation; this allows it to be used for announcements in an emergency. In common with most other Cloud products, a Music Mute control input is fitted; short-circuiting the terminals here will also activate the emergency muting circuitry.
