length) cable kit for the PROAMP-7X250.
Observe the following guidelines when installing the PROAMP-7X250:
● The PROAMP-7X250 is very heavy; therefore, two people should lift and
install the device.
● The installation location must be able to support the weight of the
PROAMP-7X250. The weight is 105.0 lbs (48.0 kg).
● When installing the PROAMP-7X250 into a rack:
– Load the rack from the bottom to the top with the heaviest components
at the bottom of the rack.
– If the rack is provided with stabilizing devices, install the stabilizers
before mounting or servicing the unit in the rack.
● When wiring the amplifier, ensure that the amplifier’s power switch is off.
WARNING: Failure to observe the following installation guidelines may
result in personal injury or damage to the equipment.
!!
Connect the PROAMP-7X250 as shown in the diagram below. Connect the
power cord last.
To connect the PROAMP-7X250 to a PSPHD, refer to the diagram below for
additional connection information.
NOTE: The PROAMP-7X250 and the PROAMPI-7X250 are functionally
identical. For simplicity, the name “PROAMP-7X250” is used throughout
this guide.
NOTE: If you are pairing the PROAMP-7X250 with the PSPHD using a
direct connection, connect the included CAT5e cable from the LAN port on
the amplifier to the LAN port on the PSPHD. When using a network
connection to the PSPHD, connect the CAT5e cable from the LAN port on
the amplifier to the local area network. When using a network connection,
the PSPHD and the amplifier must be on the same subnet. For additional
information about pairing, refer to section .

Testing Amplifier Operation
3
If desired, operation of the PROAMP-7X250 can be tested by placing the
amplifier in Override mode. Override mode turns on all amplifier channels and
ignores any commands from a control system or from a PSPHD (if connected
to the amplifier).
To place the amplifier in Override mode:
1. With the amplifier powered on, press the OVERRIDE/SETUP button on the
rear of the PROAMP-7X250. The amplifier will be in the Override mode
and the associated LED will light.
2. Test the amplifier as needed. If amplifier faults are indicated on the front
panel, refer to the latest version of the PROAMP(I)-7X250 Operations
Guide (Doc. 6974) for additional information and troubleshooting tips.
The manual is available from the Crestron website
(www.crestron.com/manuals).
3. Press OVERRIDE/SETUP to exit the Override mode. The LED will
extinguish.
The PROAMP-7X250 can be paired with a PSPHD Surround Sound Processor
for control and monitoring of the amplifier. Use the connection type that best
fits the application:
● NETWORK: Choose NETWORK if you already have a DHCP network
available and plan to eventually control the amplifier and PSPHD over a
LAN, refer to section .
● DIRECT: Choose DIRECT for a quick installation test without networking
or LAN setup. The LAN port of the amplifier connects directly to the LAN
port of the PSPHD.
To later integrate with a control system program controlling via the LAN,
the pairing process must be executed again when the amplifier is installed
on a network. The original pairing must be removed and then re-paired,
refer to section on page 3.
If the amplifier and PSPHD are to be controlled by Cresnet, pairing does
not need to be repeated.
NOTE: Pairing is for use with the PSPHD only.
