ADDITIONAL INFORMATION
Architect’s and Engineer’s Specifications
The wireless system shall utilize digital conversion with a dynamic range of greater than 118 dB without the use of compander
ICs, and operate in the UHF band between 902 MHz and 928 MHz for operation in North and South America. The system shall
transmit a digital representation of the audio signal over two separate RF frequencies that include a unique digital code
sequence that identifies the transmission to the receiver thus locking out all other sources of interference without the need of
squelch circuitry. The system shall include the option of changing the compatible preset operating frequencies enabling up to 5
systems to operate simultaneously in the same location without interfering with one another.
All transmitters shall be powered by a single 9 volt battery and shall have a power on/off button as well as a channel select
button. The bodypack will have an LED display indicating power status, battery status, operating channel and audio level.
Available transmitters shall include: a body pack for use with electric guitars, basses and other electric instruments, and lavaliere
and headset microphones for vocals. The transmitter shall have a DC/DC converter to ensure consistent performance, even if
battery voltages change.
The receiver shall have two user-selectable channel selection buttons, one for ‘next’ channel and one for ‘previous’ channel.
The receiver LED display shall indicate the current operating channel, RF present, Diversity status, Audio Level, remaining
Battery Level in the transmitter with a resolution to within 20 minute increments being preferred.
The system shall use dual frequency transmission technology such as Q-diversityPLUS and TruDIGITAL to maximize RF
performance and to eliminate interference, audio artifacts and unwanted noise. The receiver shall include four Receiver LEDs
(one for each internal receiver), automatically indicating the operating status of each internal receiver. The system shall be
capable of handling an input and output signal of up to 6 volts peak-to-peak without the use of compander ICs.
The system shall be the X2 XDR-95 Digital Wireless System.
