CTs Power Amplifi ers
Operation Manual
5 Advanced Features
and Options
5.2.4 Input Sensitivity Switches
See Figures 5.1 and 5.2. To access the Input Sensitivity Switches, turn off the
amplifi er and remove the PIP2-BBY Input Panel. The switches are in the top surface
of the cavity behind the Input Panel. One 3-position switch per channel selects
among these settings: CTs 600/1200: 1.4V (8/4 ohms), 26 dB gain, and 1.4V (70V
operation). CTs 2000/3000: 1.4V (8/4 ohms), 26 dB gain, and 1.4V (70V) / 2V
(100V). The Specifi cations chapter lists the input sensitivity for the 26 dB gain
set ting.
5.3 Options
T-170V: See Figure 5.3. This is an autoformer that
allows 100V output from the CTs 600/1200, and allows
other amplifi ers without direct constant voltage output
to be easily integrated into distributed systems.
TP-170V: See Figure 5.4. This is a rack-mountable
panel with four autoformers as described above.
PIP Modules
Versatile PIP (Programmable Input Processor)
mod ules provide fl exible expansion features that can
be added to customize the amplifi er. PIP modules plug
into the connector inside the back panel of the
ampli fi er. PIP modules are available with features
ranging from error-driven compressor/limiters to
crossovers to remote control and monitoring via
IQwic™ or System Architect software. Your amplifi er is
a PIP2 amplifi er, which means it can take advantage of
the many advanced features found in PIP2 modules.
The CTs Series 2-channel models do not accept earlier
PIP
modules.
Visit the Crown website at www.crownaudio.com, or
contact Crown Customer Service, for descriptions of
available PIP and PIP2 modules.
