24 Bit DSP Processing
The Motorola 24 Bit Digital Signal Processors decode the
back channel information from specially encoded Digital
5.1 sound tracks.
·
20 Bit Conversion
Two 20 bit stereo digital to analog, (D/A) converters are
used to reproduce the back channel information, and one
20 bit stereo analog to digital, (A/D) converter is for input
signal from the analog inputs.
·
Automatic Expansion Mode
The MSE1 automatically switches expansion modes when
receiving specially encoded Digital 5.1 sound tracks (re-
quires connections to the McIntosh MX132 A/V Control
Center). Expand nomenclature illuminates to show which
decoding mode is in use.
·
LED Output Format / Delay / Volume Indicators
The MSE1 includes four LEDs on the Front Panel to indi-
cate status of the output signal format. In addition, there is
a two digit LED indicator that shows the Trim Volume,
Time Delay and Channel Level during surround level cali-
bration.
·
Adjustable Channel Time Delays
Signals to the back Surround channels can be time delayed.
This feature can be used to correct the different listening
distances from the back surround speaker(s) and the pri-
mary listening location.
·
Built-In System Level Calibration Generator
A built-in test signal generator can be switched manually or
automatically through all surround channels for surround
level calibration. The levels can be adjusted plus or minus
6dB.
·
Automatic Input Level Control
The Analog Input includes a special circuit which protects
against accidental input signal overdrive.
