1. General Description
SoundCast 50RFM is a complete point-to-point and point-to-multipoint wireless audio solution.
SoundCast 50RFM takes a 2-channel digital stereo input signal, sends it across a robust radio
frequency link, and then converts it back to a stereo analog signal for use at a remote location.
SoundCast 50RFM is ideal for home theater rear speakers, headphones, public address systems,
and outdoor speakers.

3. Electrical Specifications
3.1 Operating Conditions – SoundCast 50RFM Transmitter
Note: All Min/Max characteristics and specifications are guaranteed over the Specified operating
conditions. Typical performance characteristics and specifications are derived from
measurements taken at typical supply voltages and TA=25oC.
3.2 Absolute Maximum Ratings – SoundCast 50RFM Transmitter
3.3 Operating Conditions – SoundCast 50RFM Receiver
3.4 Absolute Maximum Ratings – SoundCast 50RFM Receiver
4. Audio Characteristics
Notes:
FS = Full Scale
1. All measurements are for 5 bit MPX encoding.
2. RX line out into a 10 kO Load.
3. All Tests Conducted with AES Filter “In” Unless Otherwise Specified.
5. RF Characteristics
The SoundCast 50RFM algorithm is described below paying special attention to include
information pertinent to FCC and ETSI regulations. The SoundCast 50RFM software operates by
selecting a palette (or group) of 15 random channels out of the total 38 to hop on. For the 15channel palette, any channels with poor transmission rates are replaced with better channels
from the remaining 23 unused channels. The hopping pattern from channel to channel is a
random pattern. The following table describes some important aspects of the channel-hopping
algorithm:

7. Information to User
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) This device must accept
any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for Class B Digital Device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates and
can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures.
•
•
•
•
Reorient or relocate the receiving antenna
Increase the separation between the equipment and receiver
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected
Consult the dealer or an experienced radio/TV technician for help
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
8. Human Exposure Compliance Statement
KSC Industries, Inc. certifies that it has determined that the 50RFM complies with the RF hazard
requirements applicable to transmitting equipment operating under the authority of 47 CFR Part
15, Subpart C of the FCC Rules and Regulations. This determination is dependent upon
installation, operation and use of the equipment in accordance with all instructions provided. The
50RFM is designed for and intended to be used in fixed and mobile applications. "Fixed" means
that the device is physically secured at one location and is not able to be easily moved to another
location. "Mobile" means that the device is designed to be used in other than fixed locations and
generally in such a way that a separation distance of at least 20 cm is normally maintained
between the transmitter's antenna and the body of the user or nearby persons. The EUT is not
designed for or intended to be used in portable applications (within 20 cm of the body of the user)
and such uses are strictly prohibited. To ensure that the 50RFM complies with current FCC
regulations limiting both maximum RF output power and human exposure to radio frequency
radiation, a separation distance of at least 20 cm must be maintained between the unit's antenna
and the body of the user and any nearby persons at all times and in all applications and uses.
