Quick Start Guide
24. Crossover Type HP/Bandpass – The crossover of channels 3/4 
can be selected as a high-pass or bandpass type. For example, 
bandpass is super for bi-amping your speakers, with channels 1/2 
high pass for tweeters, and channels 3/4 bandpass for mid-range.
25. LP Crossover Frequency – Selects the lower frequency of the 
band to match your speakers and system (only if the crossover 
type switch (24) is set to bandpass). The channel 3/4 outputs will 
receive the frequency range selected by the HP and LP controls. 
26. Mono/Stereo – Amplifiers 3 and 4 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum). 
27. Gain Control – Adjusts the overall 3 and 4 output levels.
28. 3/4 and 5/6 Bus Sum – This sums the 3/4 and 5/6 inputs together. 
So two inputs (L/R) can feed four outputs (2L/2R).
29. AccuBASS®/ACR-1 – Enables/disables the AccuBASS® circuit and 
the ACR-1 remote level control for outputs 5 and 6. If enabled, the 
ACR-1 controls the level of the level of the 5 and 6 outputs and 
line outputs. If disabled, then it just controls the line outputs (to 
a subwoofer for example). The AccuBASS® has its own controls to 
work wonders on the lower bass of the outputs and line outputs.
30. Crossover Type LP/HP – The crossover of channels 5/6 can be 
selected as a high-pass or low-pass type.
31. Crossover Frequency – Selects the LP or HP crossover point to 
match your speakers and system. The channel 5/6 outputs will re-
ceive the frequency range above or below the frequency selected, 
depending on the setting of the crossover type switch (30). 
32. Mono/Stereo – Amplifiers 5 and 6 can be joined in mono to pow-
er a single more powerful speaker (4 Ohm minimum). 
33. Gain Control – Adjusts the overall 5 and 6 output levels.
34. LEDs:
 
MILC™ Source Clip LED – The MILC™ (Maximum Input Level 
Control) patent-pending level-setting circuit prevents clipping 
and damaging distortion. It calculates when the waveform of an 
incoming audio signal on input 1 and 2 is clipping, and if it is, this 
LED will fulfill its prime objective and shine forth.
 
With this advanced feature, you are able to optimize the level of 
the incoming audio signals until the Source Clip LED is just-prior 
to lighting. If the LED comes on during normal operation, you 
should adjust the level of the audio signals before they reach the 
LC-6.1200.
 
Gain Maximized LEDs – These LEDs indicate when the LC-6.1200 
amplifier gain for channels 1/2, 3/4, and 5/6 has been maximized 
for optimum performance.
