power cord last.

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 .

● 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:

–

–

● When wiring the amplifier, ensure that the amplifier’s power switch is off.

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.

Testing Amplifier Operation

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.

Pairing

NOTE: Pairing is for use with the PSPHD only.

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.

Pairing with a “Network” Connection

To pair the PROAMP-7X250 with the PSPHD use a “network” connection:

1. Using the NETWORK/DIRECT switch on the rear of the PROAMP-7X250,
set the connection type to NETWORK.

2. Power on the PROAMP-7X250 and the PSPHD.

NOTE: If you change the position of the NETWORK/DIRECT switch again
on the PROAMP-7X250, you must then power cycle the device in order for
the new setting to take effect.

3. Using the INSTALLER MENU on the PSPHD, pair the PROAMP-7X250

with the PSPHD:

a. To open the INSTALLER MENU, press and hold the HOME and

DISPLAY buttons simultaneously for approximately five seconds.

b. Turn the selection knob until Network Setup is displayed, and then

press the selection knob.

c. Turn the selection knob until “Pair Crestron Amplifier” is displayed, and

then press the selection knob to open the Amplifier Pairing Control.

d. Turn the selection knob to highlight Network as the connection type

between the PSPHD and the PROAMP-7X250.

NOTE: The PSPHD and the PROAMP-7X250 must be set to the same
connection type.

NOTE: When using the Network connection type, the PSPHD and the
PROAMP-7X250 must be on the same subnet.

e. Press the selection knob to select the Network connection type.

f. When prompted on the PSHPD display, press either of the following

buttons on the PROAMP-7x250 while the appropriate LEDs blink
(about two minutes):

● RESET (front panel). Press this button while the front panel
LEDs blink.

or

● OVERRIDE/SETUP (rear panel). Press this button while the red

OVERRIDE/SETUP LED blinks.
