1) Phono Input - use only with a MM cartridge type phono source. Phono
sources with MC Cartridges need to be used with an external phono preamp
connected to the Line Level Input. A ground screw is included.
2) Line Level Inputs - used with most common sources with RCA
connectors. Inputs autodetect and autoswitch in priority order. As viewed
above, the highest priority input is on the left, the lowest priority on the right.
This means that a source to the left will always interupt a source to the right
A newly activated source to the right will not interupt an existing source to
the left.
3) AES/EBU Digital Output - This is the best output format, compatible
with the highest quality and professional products.
4) Coaxial Digital Output -This is the most common output format and is
preferred over optical except where very long runs or very noisy environ-
ments are concerned.
5) Optical Digital Output - The optical format is also common on many
consumer products.
6) Power Connector - Must be connected to the desktop supply included
with the PAD. For
critical applications,
use
the
P1000
Power Base, sold
separately.
7) External Inter-
face
-
Allows
manual control over
all switching.

the LINK and a very high quality digital stream is created, with no copy
protection. Although the quality is not as good as the original, it is far better
that if the analog outputs of the source were connected to the analog inputs
of the recorder.

PERATION
The Audio Director operates automatically in most cases. The digital audio
format that is selected in the default mode is 48KHz sampling rate and 24
Bits of resolution. The Audio Director always outputs 24 bits of resolution.
If your processor or recorder is not capable of using all 24 bits, then the
additional bits above your recorders capability are concatenated. Later
when you upgrade your processor, these bits may be able to be used to your
benefit. The highest sampling rate should be used that can be accommo-
dated by your processor. The default 48KHz sampling rate is the highest
accommodated by the vast majority of processors. A higher rate can be
selected on the front panel.

WITCHING
The autoswitching in all MSB products works the same way, with subtle
differences. In all cases, when a higher priority signal is detected, the out-
put is switched to the higher priority source. This switching occurs very
rapidly. When the higher priority source is switched off, the next highest
source is selected. With digital audio and video, this switching is fast, but
with audio switching no source is considered off until it is quiet for at least 6
seconds. In this way a signal will not be lost during a quiet spot in a movie.
The setup concept is to attach your inputs with the most commonly used
inputs such as DSS or Cable attached to the lowest priority input. This
source can be left on all the time. Occationally used sources such as LD or
DVD are set at a higher priiority. When you want to watch a movie, put in
the disc and play. Its higher priority interupts the background DSS source.
When the movie is done, the system automatically goes back to the lower
priority source.

These inputs are designed to accept standard 2V Peak-to-Peak input sig-
nal. This is the THX approved output level and should be found on all
sources. Most sources can be connected directly to this input with no vol-
ume control required. Specialty and high-end products many times provide
a higher level output, specifically designed for use with passive volume
