Radial Engineering Headbone Owner’s Manual
5
Before making any connections, ensure that your ampli-
fiers are turned off, the Headbone power supply is discon-
nected, and volume controls are set to zero.
1. Begin by connecting your guitar to the Headbone’s ¼” Buffered Input.
This will allow you to test the system more effectively during the initial
setup. For unbuffered (Direct) input use, please go to the section that
discusses this on page 7.
2. From the Headbone, connect the To Amp-1 Input jack to your first
amp’s guitar input. This circuit connects the guitar to your first ampli-
fier. Always use good quality shielded cable to ensure low noise and
best performance.
3. From the Headbone, connect the To Amp-2 Input jack to your second
amp’s guitar input. This circuit connects the guitar to your second
amplifier when the footswitch is toggled.
You are now ready to connect the speaker jacks.
At this time, you should check to make sure both
amplifiers have their impedance set to match the
speaker cabinet impedance. If you are unsure about
this, consult a qualified technician. Always use good
quality speaker cables to ensure the best possible
power transfer.
4. From your first amp’s speaker output, connect to the Headbone’s
From Amp-1 Output jack. This brings the signal from amp-1 back to
the Headbone.
5. From your second amp’s speaker output, connect to the Headbone’s
From Amp-2 Output jack. This brings the signal from amp-2 back to
the Headbone.
6. From the Headbone’s To Speaker Cabinet jack, connect to your
speaker cabinet. You are now ready to start system tests.
7. Connect the Headbone’s power supply. The Headbone will turn on and
you will see one of the LEDs illuminate.
8. You can now turn on your guitar amplifiers. It is a good practice to
test equipment setups at a low volume to reduce any possibility for
system damage should there be an improper connection. Turn up
the volume slowly while listening for excessive noise. Depress the
footswitch to make sure both amps are working. If all is well, you are
ready to crank it up!
