U-14R Input Priority Module


The U-14R is a plug-in type Input Priority module designed to be used in conjunction with TOA's 900 Series and BG-1000 Series amplifiers. The U-14R is equipped with 2 inputs: BGM and JUKE, and the JUKE input has priority over the BGM input. BGM signals are only output when an input is received. Output automatically switches over to JUKE signal input when JUKE signals are received. Each of BGM and JUKE inputs has both L and R inputs, which are internally mixed and output. The JUKE input is equipped with an AGC, which maintains a uniform output level for varying input signal levels. When the U-14R is used with a 900 Series amplifier, its outputs (both BGM and JUKE) can be turned off using the two MUTE BUS signal channels.
