Description

The UMA 1502 are high quality, commercial grade analog audio mixer/amplifiers. Designed for flexibility in application, these mixer/amps represent the latest, state-of-the-art technology in analog circuit design.

Powerful, yet easy to use, the new UMA 1502 delivers amazing sonic performance. Low-noise design and features applicable to “real-world” situations makes this unit ideal for audio applications where a compact, powered mixer with multiple input and output capabilities are required.

Architectural and Engineering Specifications

The mixer/amplifier shall have 4-inputs and an accessory module port for use with present and future Peavey MMA modules. The front panel shall include four input level controls, bass and treble controls, and a master output control. Front panel indicators shall include power, signal presence at the amplifier, channel signal and mute condition, and SPS™. The mixer amplifier shall have a hierarchical muting function where the input module has the highest priority followed by Channel 1. Outputs shall include one direct and three transformer-balanced. The power switch shall be on the rear panel along with the detachable IEC cord, fuse holder, and accessory power outlet (120 V only).

There shall be four inputs with Euro-type connectors on the rear panel and level controls on the front panel. Channel 1 shall also include an XLR connector and have a bridging transformer input with switchable input sensitivity between telephone paging and microphone. When in the microphone mode, 24 Volt phantom power shall be applied to the Input 1. Channel 2 shall be electronically balanced with a switchable input sensitivity between mic and line levels. When in the microphone mode, 24 Volt phantom power shall be applied to the Input 2. Channels 3 and 4 shall be electronically balanced line-level inputs with Channel 4 including stereo RCA jacks. Additionally, the output from Channel 4 input shall be made available via an electronically balanced output with a Euro- type connector and a separate level control. The module port shall be capable of controlling both mute buses. Depending upon the module chosen, it can be set up for master configuration. When the input signal to an input module commands a mute function, Channels 1-4 shall be muted.

Only Channel 1 shall have a continuously variable mute threshold control on the rear panel. Setting this control fully clockwise shall defeat the Channel 1 mute function. The mute level threshold for Channel 1 shall be increased as the control is turned clockwise. When the signal level in Channel 1 exceeds the mute threshold, Channels 2-4 shall be muted. Channels 1 and 2 shall include a switch to defeat its muting function. When the switch is out, the channel shall be muted. When the switch is in, the channel cannot be muted.
