STEP 2: CONNECT AUDIO CABLES
Turn off your radio, your computer and
RIGblaster
before connecting cables.
1) Disconnect your computer speakers and any external radio speakers. Choose the best pair of
amplified or unamplified speakers. They do not have to be a matched pair but that is preferred for
playing music. You may use any pair of 4-16 ohm speakers or any amplified computer speakers. Some
amplified computer speakers are may be susceptible to picking up RF interference. Our RF resistant
COMspkrs
are designed to solve that problem. Connect the speakers to the (
R10)
speaker out jack.
This jack is a stereo jack with the tip left, ring right and sleeve common. A cable is not supplied because
most computer speakers have a matching stereo connector, or you may have to fabricate a speaker cable
to connect a pair of unamplified speakers.
2) Use the supplied 1/8” stereo mini phone plug cables and connect the speaker output of radio A to
“RADIO A IN” (
R13)
. Likewise, connect radio
B
to (
R12)
.
3) Connect your computer’s line output, usually a green socket
on the back of a computer, (laptops
use the headphone jack
) to the to the PC IN (
R11)
jack on the
RIGblaster duo
.
3) Turn on the
RIGblaster
, your radios and computer. Turn radio A’s volume control (AF gain) about
half way up (12 o’clock). Select radio A on the RIGblaster by flipping the “radio A” switch
(F6)
to the
up/top position. Turn up the “rx level” (master volume) knob
(F5)
on the RIGblaster and you should
hear radio A coming from your speakers. Try the Same thing with radio B using the “radio B”
(F7)
switch. Play music or cause your computer to generate audio and select “PC”
(F8)
and you should hear
you computer.
4)Plug headphones into the RIGblaster
(F2)
and turn up the RIGblaster’s “ph level” (headphone sub
volume) knob
(F9)
and you should hear the same thing coming out of your headphones that is coming
out of your speakers.
Experiment with all the controls!
Congratulations! This completes the basic installation of the
RIGblaster duo
. Your station will be
much neater and more convenient to use, while doing everything it did before.
OPERATING BASICS
You must have the
RIGblaster
turned on in order to operate your station. Note that there is a 12 volt
remote trigger output on the back
(R2)
provided to turn your entire station on or off. Look for future
accessories from West Mountain Radio to do this or home brew a box with 12 volt relays to control your
station’s DC, AC or both.
BASIC FUNCTIONS:
TRANSMIT SELECT is done by using the “xmit select”
(F3)
to select which radio will be used for
transmitting. Either your PTT switch or computer will activate transmit and the audio will be
