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
amplifier 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 Specifications 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 amplifiers 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 flexible expansion features that can be
added to customize the amplifier. PIP modules plug
into the connector inside the back panel of the ampli-
fier. 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 amplifier is a PIP2 amplifier,
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.
