• Two stereo line inputs provide amplification for a DVD player, laptop
computer, or other program sources
• Speech and program audio signals are independently adjustable via a
control on the wireless mic*
• “Ducking” feature automatically turns down the program source
whenever the instructor speaks
• Built-in master volume, bass, and treble adjustment helps optimize the
overall sound quality
• High-efficiency, energy-saving design minimizes power consumption
during operation and while idle
• Includes external power pack and external antenna(s)

Setup
Installation
The MP-FS-RX1/RX2 can be placed on any convenient flat surface in the room,
such as a desk, shelf, table, or ceiling-mounted third-party equipment platform.
• Install all accessory hardware, including power pack, MP-FSIR Beacon
Sensor(s), MP-FS-PAS Audio Sensor, FS6 or FSDI8 speakers, following
their supplied instructions.
• For the MP-FS-RX1, attach the supplied single antenna; for the
MP-FS-RX2, attach the cables from the two supplied antennas (the antennas
should be spaced at least 6 feet (~ 2 meters) apart.
• Orientation of antennas for desk, shelf, or table mounting installations
should be straight up. For ceiling mounted installations (including the
MP-FS-RX1 on a third-party ceiling-mounted equipment platform), antenna
orientation should be straight down. For wall-mounted installations, the
antennas should be at a 45° angle, either up or down, from the wall.
• Install all other required interconnecting cables.
Hardware Hookup
Make the necessary connections as called out in the illustration that follows this
paragraph. Apply power after all connections have been made.
When making connections to the MP-FS-RX1/RX2, note the following:
• Use Crestron power supplies for Crestron equipment.
Hardware Connections for the MP-FS-RX1/RX2
NOTE: Ensure the unit is properly grounded by connecting the chassis ground lug
to an earth ground (building steel).

Uploading and Upgrading
Crestron recommends 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
established, firmware can be transferred to the device.
Establishing Communication
Use Crestron Toolbox™ for communicating with the MP-FS-RX1/RX2; refer to the
Crestron Toolbox help file for details. There is a single method of communication:
USB communication.
USB Communication
The COMPUTER port on the MP-FS-RX1/RX2 connects to the USB port on the
PC via the included Type A to Type B USB cable:
1. Use the Address Book in Crestron Toolbox to create an entry using the
expected communication protocol (USB).
2. Display the MP-FS-RX1/RX2’s “System Info” window (click the
icon); communications are confirmed when the device information is
displayed.
Firmware
Firmware files may be distributed from programmers to installers or from Crestron
to dealers. Firmware upgrades are available from the Crestron Web site as new
features are developed after product releases. Upgrade via the Crestron Toolbox. For
details on upgrading, refer to the Crestron Toolbox help file.

Single/Dual-Channel Wireless Mic Receiver Crestron MP-FS-RX1/RX2
Operation
Basic Procedures
Before beginning, ensure that the MP-FS-RX1/RX2 receiver is installed and
connected as instructed in “Setup” on page 8, that power is on (the green LED is on),
that line level audio is supplied from a DVD player, a laptop computer, or other
device, and that the MP-FSMIC microphone has been fully charged.
Microphone Button/LED Functions
During the following verification procedures, refer to the illustration above.
Pair Microphone with Receiver
1. Hold the MP-FSMIC ON button until the mic Status LED rapidly flashes green.
2. The mic will begin pairing with the receiver. Make sure the mic has line of sight
proximity to the MP-FSIR. When pairing is complete, the Status LED will
slowly blink green. Time to pair is typically between five and ten seconds.
The mic must be turned off and turned on again to pair to another receiver.
Mute and Volume Adjustments
1. Press the MUTE button to mute the mic (observe the blink pattern); press it
again to un-mute. When muted, the mic automatically turns off after two
minutes.
2. When the mic is not muted, the VOL button can be used to adjust the mic
volume.
3. When the mic is muted, the VOL button adjusts the line level audio volume.
4. Line volume is automatically “ducked” (reduced) when the user talks into the
mic.
5. Hold the MUTE button for five seconds to turn off the mic (turns off
automatically if muted for two minutes, or when placed in the charger.)
6. If the mic loses sight of the MP-FSIR for seven seconds (time is configurable),
the mic will automatically mute (turns off automatically if muted for two
minutes).
7. If RF link is lost for 10 seconds, mic turns off.
Emergency Trigger
Hold the ALERT button for eight seconds (time is configurable) to generate two
beeps from the speakers and close the alert relay contacts until the button is released.

Receiver Controls - Default Settings
BASS and TREBLE: Typically, set these controls to their center detent positions.
Slightly reducing treble can help to reduce feedback.
MASTER VOLUME: Have the instructor speak from the most likely position in the
room and adjust this control clockwise so that the speakers just begin to exhibit
feedback, and then reduce the setting slightly by turning counterclockwise.
