automatically selected between the mic and computer. The position of the switch indicates which is
selected, A or B. Remember which radio is which and that A is up and B is down. In the heat of a
contest you will hardly have to look at the switch as you will become used to selecting you’re radio by
“feel”. You may also connect transmit ready LED indicators to be located remotely on each radio to
make it more obvious which radio is ready to transmit.
RECEIVE MONITORING allows selection of any combination of radio A, B and/or the computer to
hear on speakers and/or headphones. Each input (audio source) has a switch with three positions, “off”
(down), “hp” (headphones only, center) and “both” (headphones and speakers, up). The three inputs are
mixed together and capable of stereo operation. The default configuration, set by internal jumpers (see
advanced options), is so radio A and B are played through both channels in dual-mono.
VOLUME ADJUSTMENT is quite flexible but you will have to experiment with it and get used to it.
Each radio has a volume adjustment as does your computer, and you should already be familiar with
these controls. You may also be using amplified speakers with their own volume knob.
The
RIGblaster duo
has two volume knobs. The “rx level”
(F4)
is the master volume for the entire
station! You will have to get used to using it as the main volume for the station. For example, if the
phone rings or the family calls it can be used to turn down the entire station.
There is also a separate “ph level”
(F9)
headphone volume control. The headphone volume is
controlled by this knob in relation to how loud the master volume is set. This allows you to set the
headphones louder or softer than the speakers. Note: now you can work that weak station you can
barely hear on your speakers simply by putting your headphones on. Your headphones will be playing
the same thing, they are already plugged in and they can be set louder than your speakers.
To setup the volume for the entire station, set each radio’s AF level (volume control) about half way up.
Set your computer’s virtual sound card level control about 2/3 of the way up. If you have amplified
speakers with a volume knob set that about 2/3 of the way up. Start by selecting radio A to play on
speakers and headphones, “radio A”
(F6)
in the up position. Turn up the “rx level” for a comfortable
volume. Turn off A and turn on B, set that radio’s AF level to match your other radio. Next do the same
thing with the computer, using the virtual master volume slider. Now experiment with switching
between the sources and listening to more than one source at a time. You will find you can balance
everything the way you wish and to use the master “rx level” as the main volume. It will take you
awhile to get out of the habit of using the knobs on the radios or computer slider, leave them alone. Plug
in headphones and experiment with the “ph level” and selectors. You will quickly get used to
controlling everything from the
RIGblaster duo
central location.
We hope that you find the basic operation completely intuitive and obvious, simply by looking at the
front panel of
RIGblaster duo
and experimenting with the controls.
