7.1 INPUT –6.1 OUTPUT

The Front and Surround channel inputs are passed to the Front and Surround channel outputs.

The LFE and the low-frequency contents of the Front, Surround and Rear inputs, may be

optionally mixed and passed to the SUB output. The RC OUT channel is obtained from:

(RL IN + RR IN)/2

BASS MANAGEMENT

The Bass Management function filters and combines the input signals to produce a low-pass filtered

output for the sub-woofer channel and high-pass filtered outputs for the remaining channels. The

filters have selectable cut-off frequencies to match different types of sub-woofer and satellite

speakers. The filters are designed so that the cut-off frequencies for the high-pass and low-pass

filters remain constant irrespective of the sampling frequency used. 1

st order filters are used for the

low-pass and high-pass filters.
