phone Auto-Cue select.
Studio Module
The optional Studio module (PRE99-1319) is
installed to the right of the Control Room module.
It provides a monitor and talkback-level control
for one studio or voice booth. The monitor source
can be any combination of 11 sources (four exter-
nal inputs, four programs, Send, and Telco Record
and Monitor) simultaneously.
The Studio module has a 14-pin parallel logic
connector for external dimming or muting of the
studio monitor speakers and control of a studio
warning light interface. Controls also provide the
ability to talk to or from a studio and an external
location.
Output Modules
Two Output modules ship standard with the
Legacy.
The Output 1 module (PRE99-1320) contains
the digital-to-analog converters and mix matrices
for creating mix-minus foldbacks to support up
to four Telco/Codec modules. It also contains in-
dividually mixed outputs for Telco/Codec record-
ing. There is a mix-minus output for each Telco/
Codec module. Digital and analog outputs are pro-
vided for the mix-minus and recorder feed out-
puts. For digital outputs, sample rates of 48 kHz
and 44.1 kHz are supported. The mix-minus ana-
log outputs are fixed at +4 dBu. This module fea-
tures output sample rate selectors for digital out-
puts and a gain trim control for the analog Telco
record mix output.
The Output 2 module (PRE99-1321) contains
the AES digital output drivers, digital-to-analog
converters, and analog line amplifiers for the Send
output and the four program outputs. The digital
output sample rate is 48 kHz. An output sample
rate of 44.1 kHz can be selected for the program
1 and 2 auxiliary outputs, the program 3 and 4
outputs, and the Send output. Gain trim controls
for the analog outputs are also provided.
Power Supply
The separately packaged rack-mount power
supply assembly (PRE99-1202) uses keyed con-
nectors to supply a 48 volts DC to the con-
sole mainframe. There are two connectors from
the power supply assembly to the console: one con-
nector supplies DC power and the other supplies
electrical signal information to the console. The
power supply module has an on/off switch and
an LED indicator on the front panel. The power
supply is fully regulated and protected against ex-
cessive current by internal fuses and electronic
safeguards.
