• Using the hardware provided, the HD-XSPA can be installed in an

equipment rack or placed on a shelf.

Keyboard/Mouse Extender

When connected to a DigitalMedia switcher or transmitter, the HD-XSPA

can function as a keyboard/mouse extender. Via its rear panel USB port, a

USB HID-compliant keyboard and/or mouse can be connected and used

to control a computer or media server in the central equipment cabinet (or

any other location).

Other types of USB devices, including mobile phones, media players, Web

cameras, flash drives, and game controllers, can be supported by adding

a USB-EXT-DM-REMOTE extender module

[2]

. Also, a local host computer,

media server, or game console can be controlled from a remote location by

adding a USB-EXT-DM-LOCAL extender module

Amplifier Monitoring and Protection

For systems utilizing in-wall or in-ceiling speakers, itís critical that the

amplifier driving those speakers possesses the intelligence to protect itself

in the event of a shorted or damaged speaker line. The HD-XSPA includes

sophisticated protection from many types of faults on a per channel basis.

In the event of a fault, the front panel LCD provides clear fault indication to

speed the troubleshooting of damaged or incorrect wiring, poor rack

ventilation, and other unforeseen issues. Fault alerts may also be

broadcast to a touch screen or mobile device, and integrators can even

monitor and track the data remotely to ensure a rapid service response.

Speaker Protection

Configurable output limiting assures maximum headroom while preventing

damage to the speakers. The limiting threshold is easily set to match the

power handling capability of each speaker, achieving a completely

transparent effect right up to the speakers’ limits without fear of

overpowering them.

Speaker Profiles

The Speaker Profiles feature delivers excellent sound quality quickly by

allowing installers to save and load EQ and Speaker Protection settings for

all of the speakers they sell and install. Tuning a complete surround sound

system can be as easy as loading the appropriate Speaker Profile for each

speaker. Additional simplified settings are included to compensate for a

room’s size, materials, and speaker placement. A complete set of profiles

is provided for Crestron Essence

, Aspire

, Excite

, and AIR

speakers,

allowing any installer to achieve a great sounding system without touching

a single EQ setting.

70/100V Option

For ultimate versatility, the HD-XSPA can be equipped for use with 70 or

100 Volt speakers. Also known as “constant-voltage”, 70 Volt and 100 Volt

speaker systems allow for long wire runs using small-gauge wire, with the

potential for connecting numerous speakers per circuit. Typical

applications include outdoor speaker zones and commercial environments.

Any of the HD-XSPAís amplifier outputs can be converted to 70 or 100 Volt

using Sonnex Output Transformers (SAT-70V/100V-2 or SAT-70V/100V-4

[2]

Device Control Ports

The HD-XSPA includes an assortment of built-in control ports to allow for

programmable control of the local AV components and other room devices

without the need for extra control modules or wiring. Each control port is

addressable from a Crestron control system, whether that control system

is installed locally or in another room. Ethernet, RS-232, IR, and low-

voltage relay ports provide for control of the display device and AV sources,

and may also be used to control a motorized screen or lift, window

treatments, lighting, and other equipment in the room. Many AV devices

can also be controlled directly via the HDMI ports. Four “SENS” inputs are

also included to accommodate power sensors, motion detectors, and other

contact closure devices.
