Description
The UMA 752 is a high quality, commercial grade analog audio mixer/amplifier. Designed for flexibility in application, this mixer/amp represent the latest,
Powerful, yet easy to use, the new UMA 752 delivers amazing sonic performance.
Architectural and Engineering Specifications
The mixer/amplifier shall have
There shall be four inputs with
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
