STEREO INPUT – STEREO OUTPUT
The Front-Left and Front-Right inputs are passed to the Front-Left and Front-Right Outputs. All other
channels are muted.
STEREO INPUT – 2.1 OUTPUT
The Front-Left and Front-Right inputs are passed to the Front-Left and Front-Right Outputs. The low-
frequency contents of the Front inputs, may be optionally mixed and passed to the SUB output. The
Surround, Front Centre and Rear Centre channel outputs are muted.
5.1 INPUT – 2.1 OUTPUT
Stereo mix-down is not supported. In this mode, the Front-Left and Front-Right inputs are passed
to the Front-Left and Front-Right Outputs. The LFE and the low-frequency contents of the Front and
Surround inputs, may be optionally mixed and passed to the SUB output. The Surround, Front Centre
and Rear Centre channel outputs are muted.
5.1 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 and Surround inputs optionally, may be
mixed and passed to the SUB output. The RC OUT channel is obtained from the surround
channels according to the equation:
5.1 INPUT – 5.1 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 and Surround inputs, may be optionally
mixed and passed to the SUB output. The Rear-Centre channel is muted.
6.1 INPUT – 2.1 OUTPUT
Stereo mix-down is not supported. The Front-Left and Front-Right inputs are passed to the Front-
Left and Front-Right Outputs. The LFE and the low-frequency contents of the Front, Surround and
Rear-centre inputs are optionally mixed and passed to the SUB output. The Surround, Front Centre
and Rear Centre channel outputs are muted.
6.1 INPUT – 5.1 OUTPUT
The Front channel inputs are passed to the Front channel outputs. The LFE and the low-frequency
contents of the Front, Surround and Rear-centre inputs, may be optionally mixed and passed to the
SUB output. The RC IN channel is mixed into the SL OUT and SR OUT output channels according to
the equations:
The Rear-Centre output channel is muted.
6.1 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-centre inputs, may
be optionally mixed and passed to the SUB output. The RC OUT channel is obtained from
either RL IN or RR IN (dependent on setting of register bit RCFG).
7.1 INPUT – 2.1 OUTPUT
Stereo mix-down is not supported. The Front-Left and Front-Right inputs are passed to the Front-
Left and Front-Right 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 Surround, Front Centre and
Rear Centre channels are muted.
7.1 INPUT – 5.1 OUTPUT
The Front channel inputs are passed to the Front 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 RL IN and RL OUT channels are mixed into the SL OUT and
SR OUT channels according to the equations:
The Rear-Centre output channel is muted.
SL OUT = (SL IN + RL IN)/2, SR OUT = (SR IN + RR IN)/2
RC OUT = (SL IN + SR IN)/2
SL OUT = (SL IN + RC IN)/2, SR OUT = (SR IN + RC IN)/2
