AccuBASS® and ACR-1 Notes

AccuBASS®switches
 

The AccuBASS switches 1/2, 3/4, and 5/6, allow you to add the 

AccuBASS circuit into any speaker-level output pair: 1/2, 3/4, and 

5/6 respectively. So each output can have the AccuBASS active, 

and its effect controlled by the settings of the AccuBASS level and 

threshold controls.

 

The AccuBASS gets its input signal from the 1/2 inputs, via the 1-2 

bus. If the bus switches are set to SUM, then the AccuBASS will 

also receive signals from inputs 3/4 and/or inputs 5-6.

ACR-1 remote
 

The ACR-1 remote level control affects the level of the signal after 

the AccuBASS circuit, and the ACR-1 only affects those channels 

that have the AccuBASS switch engaged.

Line-level outputs
 

The 2 RCA line-level outputs always have the AccuBASS engaged, 

and the level can be adjusted by the ACR-1, without setting any 

switches. In this way, the line-level outputs can be directed to 

an external subwoofer amplifier for example, and have its level ad-

justed by the ACR-1, and the AccuBASS working its magic on the 

subwoofer tones.

The long-awaited moment when “plethora” is used in a manual
 

The plethora of LC-6.1200 controls allows for a wide variety of in-

stallation possibilities. This quick start guide gives a few examples 

of system diagrams, and includes a few notes about the control 

settings for each one. 

 

Note: The technical writer reserves the right to be wrong about things, due to the 

cold medicine being the night-time sleepy stuff, and not the usual day-time strength.
