U-61S Unbalanced Line Input with Compressor
• For Unbalanced, Line Level Sources such as AM/FM
tuners, cassette decks, CD players, computer sound cards,
jukeboxes, mixers and satellite receivers.
• Use For Adjacent Sources (less than 15 feet from the
host unit).
• Compressor Function Helps Prevent Overload And
Distortion
, activates when the module's input signal
exceeds a preset, adjustable threshold.
• Compression Ratio: 2:1 (fixed) reduces the module's
output signal level to 1 dB for every 2 dB increase in input
signal level.
• Tip! You can also use the U-61 as a standalone
Compressor or Master Compressor by cutting Jumper J2 to
disconnect the module's output from the mix bus. Connect
the "Pre-Out" jack (or mixer output) to the module input and
the "Power-In" jack (or adjacent power amplifier) to the
module output.
• Connector: removable terminal block (U-61S).
