6.  INSTALLATION

6.1  TOOLS

BIAMP Systems recommends using the
SC-300 (User Control Interface
software) when installing and setting up
any Voicecrafter product.  In some
applications a Hand-Held Terminal may
be used instead.  In order to achieve
more accurate adjustment of the
Voicecrafter, it is also recommended
that the following additional test and
measurement tools be employed:

1) Sound Pressure Level meter, 

such as Extech model 407750.

2) White/pink noise source, with 

speaker and variable level.

In some installations it is useful to
display levels within the Voicecrafter. A
third-party software program has been
developed for this purpose.  This
program is available by contacting:
Ed Lethert @ Ed Lethert Associates.
Phone: (612) 545-0030

6.2  CONNECTIONS

SPEAKER:  5 Watts of power is
available into a 4 ohm minimum speaker
load.  Wire the speaker positive to the
Red (+) terminal, and wire the speaker
negative to the Black (-) terminal.
