SYSTEM SETTING AND OPERATION:
THE INPUT FOR WIRED MICROPHONES
Connect the 6.3 mm jack plug of your microphone cable to the MIC Jack input. This input is located on the back of
the Roadboy. Make sure that the other end of the cable is properly connected to the microphone. If your microphone is
equipped with a power switch, please turn it off. Set the optimal microphone level by turning the MIC gain control (in
relation to the line level). If the microphone volume is set too high, it can cause distortion (overdrive).
THE RADIO RECEIVER MODULE
To begin, set the MASTER VOLUME of the Roadboy to "0". Then turn the POWER-VOL-button of the receiver module
to the central position ("12 o'clock"). Now you can synchronise the transmitter (Handheld microphone or Belt Pack
Transmitter) with the built-in receiver, using the ASC-function. Press the ASC button on the radio receiver module;
the ASC LED flashes red.
If you use a Handheld Transmitter: the infrared sensor (IR) is located in the battery compartment below the
capsule. Hold it close to the IR sensor of the receiver module.
If you use a Belt Pack Transmitter: it is also necessary to enable the ASC function on the Belt Pack Transmitter.
Hold the infrared sensor of the Belt Pack Transmitter ("IR", on the back) close to the IR window of the receiver module.
The synchronisation will take a few seconds. If you have installed a second radio module (optional), please make sure
that both modules do not operate on the same frequency (see frequency list). This will avoid interference. The flashing
of the "RF" LED indicates that your system is working properly and that the synchronisation was successful. Now you
can set the MASTER volume of your Roadboy to the desired volume level.
The maximum distance between the wireless microphone (or Belt Pack Transmitter) and the receiver module is
approximately 60 m in open space.
THE "EXT. SPEAKER" OUTPUT
To connect an external speaker, use a speaker cable with a 6.3 mm jack plug. The speaker should have an impedance
between 4 and 8 Ohm and a minimum capacity of 25 W.
HOW TO CHARGE THE BATTERY OF THE ROADBOY
When you want to operate the system without battery or while charging the battery, connect the power supply
provided with the Roadboy (16 V / 3 A). The charging time is 8 hours. When the battery is fully charged, the charging
process stops automatically. You can also operate the Roadboy while connected to the power supply.
IMPORTANT INFORMATION!
If you re-insert or replace the battery, it is ESSENTIAL that you observe the polarity! Red = + (plus) //
black = - (minus).
Recharge the battery fully at every opportunity. Never completely discharge a rechargeable lead
battery or store it in discharged or semi-charged condition. During extended periods of disuse and
storage, the battery must be recharged fully at regular intervals.
