Crestron PROAMP(I)-7X250 PROCISE™ Surround Sound Amplifier
PROCISE™ High-Definition
Professional Surround Sound
Amplifier: PROAMP(I)-7X250
Introduction
The PROAMP-7X250 and PROAMPI-7X250 seven-channel amplifiers are the

Sound Processor (sold separately), delivering 250 Watts per channel, with XLR
balanced inputs, Cresnet
monitoring through the PSPHD front panel.
The PROAMP-7X250 and PROAMPI-7X250 are functionally identical. For
simplicity within this guide, the term “PROAMP-7X250” is used except where
noted.

The Power to Inspire
The PROAMP-7X250’s custom hybrid design achieves the warmth and neutrality of
a Class AB amplifier with all the efficiency benefits of modern Class D.
The PROAMP-7X250 delivers 250 Watts at 8 Ohms, and 450 Watts at 4 Ohms, per
channel. Twin 1 kVA toroidal power transformers direct pure, continuous power to
its seven mono amplifier channels.
Efficiency
An ultra-efficient circuit and chassis design enables the PROAMP-7X250 to produce
greater output power in considerably less space compared to other amplifiers. The
PROAMP-7X250 accomplishes its class-leading performance in a mere five rack
spaces while maintaining effective cooling with no need for extra clearance above or
below.
Pairing
Together, the PROAMP-7X250 and PSPHD processor possess the unique ability to
operate as one, affording functionality unattainable from any other amp/preamp
combination. Through a simple Ethernet connection, the two components become
paired, enabling seamless control and monitoring of the amplifier through the
PSPHD’s front panel. While the PROAMP-7X250 provides indication of signal and
fault conditions on its own faceplate, you can actually confirm the specific fault
condition, check the real internal temperature, and monitor the output level of each
amp channel on the face of the PSPHD. Pairing the two components also streamlines
remote control and monitoring through a Crestron control system, providing
programmers with a unified device interface for all functions.
Protect, Monitor, Control
To help ensure the most seamless user experience and long-lived operation from
your amplifier, the PROAMP-7X250 provides several ways to assume control of its
essential functions and keep tabs of its operating status and health. On its own, the
PROAMP-7X250 possesses the intelligence to protect itself from many types of
faults including over temperature, over current, over voltage, under voltage, and DC
offset on any channel. Its front panel indicators help alert the user to any fault
condition, and provide verification of signal activity and clipping. More detailed
status monitoring is available when paired with a PSPHD processor.
For the greatest flexibility, the PROAMP-7X250 includes both Cresnet and high-
speed Ethernet to enable direct control and monitoring via a Crestron control system
(in lieu of a PSPHD). Whether communicating with the control system directly or
via a PSPHD, the PROAMP-7X250 lets you control amplifier power, mute
individual channels, monitor temperature and signal status, and receive fault alerts,
all from a Crestron touchpanel, computer or mobile device. Signals from the
amplifier may also be utilized to enable custom automation, such as reducing audio
levels when clipping is sensed, or regulating climate control in the equipment room
in response to amp temperature.
Professional & Precise
The PROAMP-7X250 is designed to produc e pristine, accurate audio. A hybrid, DC
coupled topology preserves the audio signal throughout without coloring or adding
noise.
