PROCISE™ Surround Sound Amplifier Crestron PROAMP(I)-7X400
The Power to Inspire
The PROAMP-7X400’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-7X400 delivers 400 Watts at 8 Ohms, and 700 Watts at 4 Ohms, per
channel. Twin 1.8 kVA toroidal power transformers direct pure, continuous power to
its seven mono amplifier channels, each with its own isolated power supply featuring
an immense 168,000 µF total capacitance for wide dynamic range and headroom.
Efficiency
An ultra-efficient circuit and chassis design enables the PROAMP-7X400 to produce
greater output power in considerably less space compared to other amplifiers. The
PROAMP-7X400 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-7X400 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-7X400 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-7X400 provides several ways to assume control of its
essential functions and keep tabs of its operating status and health. On its own, the
PROAMP-7X400 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-7X400 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-7X400 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-7X400 is designed to produc e pristine, accurate audio. A hybrid, DC
coupled topology preserves the audio signal throughout without coloring or adding
noise.

If the amplifier and PSPHD are to be controlled by Cresnet, pairing does
not need to be repeated.
• NETWORK: Choose NETWORK if you already have a DHCP network
available and plan to eventually control the amplifier and PSPHD over a
LAN.
The following diagram shows a typical system arrangement where a
PSPHD is connected to the amplifier over an Ethernet network.
For details on pairing the PROAMP-7X400 with a PSPHD, refer to the latest version
of the PROAMP-7X400 Quickstart (Doc. 6977) and the PSPHD Operations Guide

Earliest Version Software Requirements for the PC
NOTE: Crestron recommends that you use the latest software to take advantage of
the most recently released features. The latest software is available from the Crestron
website.
Crestron has developed an assortment of Windows®-based software tools to develop
a controlled system. You can create a program to control the PROAMP-7X400 using
the Crestron programming tools SystemBuilder™ or SIMPL Windows. For the
minimum recommended software versions, visit the Version Tracker page of the
Crestron website (www.crestron.com/versiontracker).

Configuration Manager
Programming with Crestron SystemBuilder
Crestron SystemBuilder is the easiest method of programming but does not offer as
much flexibility as SIMPL Windows. For additional details, download
SystemBuilder from the Crestron website and examine the extensive help file.
Programming with SIMPL Windows
NOTE: While SIMPL Windows can be used to program the PROAMP-7X400, it is
recommended to use SystemBuilder.
SIMPL Windows is Crestron’s premier software for programming Crestron control
systems. It is organized into two separate but equally important “Managers”.
Configuration Manager is the view where programmers “build” a Crestron control
system by selecting hardware from the Device Library.
NOTE: When paired with a PSPHD, the amplifier does not need to be added to the
SIMPL Windows program. Adding the amplifier to the program is recommended
when a paired PSPHD is not present in the system.

Uploading and Upgrading
Crestron recommends using the latest programming software and that each device
contains the latest firmware to take advantage of the most recently released features.
However, before attempting to upload or upgrade it is necessary to establish
communication. Once communication has been esta bl i shed, files (for example,
programs or firmware) can be transferred to the control system (and/or device).
Finally, program checks can be performed (such as changing the device ID or
creating an IP table) to ensure proper functioning.
Establishing Communication
Use Crestron Toolbox for communicating with the PROAMP-7X400; refer to the
Crestron Toolbox help file for details. There are two methods of communication.

Operations Guide – DOC. 6976A PROCISE™ Surround Sound Amplifier: PROAMP(I)-7X400 • 23
In order to ensure optimum performance over the full range of your installation
topology, Crestron Certified Wire and only Crestron Certified Wire may be used.
Failure to do so may incur additional charges if support is required to identify
performance deficiencies because of using improper wire.
When daisy-chaining Cresnet units, strip the ends of the wires carefully to avoid
nicking the conductors. Twist together the ends of the wires that share a pin on the
network connector and tin the twisted connection. Apply solder only to the ends of
the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.
Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the number of
Cresnet devices on a network exceeds 20 or when the combined total length of
Cresnet cable exceeds 3000 feet (914 meters).
