Overview - Radial Engineering Tonebone SWITCHBONE V2 User Manual

WARNING
Only connect electrical equipment that is properly grounded with a 3-prong AC plug.
Older amps with 2-prong plugs should be serviced before using them with any amp
switcher. An improperly grounded amp can be a very dangerous thing and never
should be used in multi-amp setups.
Radial Engineering takes no re spon si bil i ty for how the Switchbone V2 is connected or
used. It is the user's full re spon si bil i ty to ensure that proper electrical connections are
maintained on all equipment connected to the Switchbone V2 and that proper building
electrical codes have been followed wherever the Switchbone V2 is used.
Note that damage to the Switchbone V2 or other connected equipment caused by
improper wiring or improperly grounded equipment is not covered under the warranty.

OVERVIEW

The Switchbone V2 is a multi-purpose buffer, switcher, power booster
and performance enhancer all in one. The best way to approach it is to
break each section down into modules and then bring them together in
your mind to suit your setup.

BUFFER GAIN BOOST
Input buffer and Drag control
minimize artefact and harshness, a 100% discrete class-A buffer is
employed. This is augmented with Drag™ control load correction to
allow the guitarist to precisely adjust the load on the pickup for the most
natural tone. A Baseline™ level control lets you increase the buffer drive
circuit to hit your amp harder or compensate for extra long cables. This
is particularly effective when using older amplifi ers that do not have input
and master level controls.

In order to minimize switching
noise and signal loss, the
Switchbone V2 is active. In other
words, it employs a buffer to
amplify and manage the signal
before the switching occurs. To

SLINGSHOT INTERNAL JUMPERS
The Switchbone V2 has internal jumpers as an added feature to give
further control of what footswitch sends the signal to another device. To
access the internal jumpers remove the top shell to expose the board.
BOTH (LEFT) OUT-C (RIGHT)
You will see the jumper in the default position on the far right labeled
OUT-B. This will allow the Slingshot to be activated either on the
TOGGLE or BOOST depending on the position of the recessed switch.
When using in ABY confi guration
When using the Switchbone V2 as an ABY switcher, where the BOTH
footswitch activates amps A and B simultaneously, you can set the
Slingshot output to send a signal when the BOTH footswitch is activated.
To do so, move the internal jumper to the left position labeled BOTH.
When using in AB/C confi guration
When you have three amps connected to the Switchbone V2, and the
BOTH footswitch activates amp C, you can set the Slingshot output to
send a signal when you activate the third amp with the BOTH footswitch.
To confi gure the Switchbone V2 in this way, move the internal jumper to
the middle position labeled OUT-C. Note that if you change back to an
ABY setup with only two amps, you will need to change this jumper again
for the Slingshot output to work.
