Making Connections - Radial Engineering Tonebone SWITCHBONE V2 User Manual

MAKING CONNECTIONS

Before making connections, always ensure the volume levels on
your amps are turned off as this will avoid power-on and plug-in
transients that could reduce the lifespan of your speakers and other
sensitive components. Connect the included 15VDC power supply
to the Switchbone V2. There is no power switch, as soon as power is
connected, you will see one of the LED's illuminate and it will spring
to life. The Switchbone V2 is equipped with a cable lock to secure the
power supply into place. Simply loosen the hex screw and pass the
power cable through the clamp in a compact loop.
Set all of the controls and switches to the start position:
BOTH/OUT-C
In the OUT
position
IMPORTANT
OUT-A is your primary output and should always be used. It should be connected
to an amp that is properly grounded with a three prong U-ground for safety. Never
remove the safety ground on your amp as this is both illegal and there to protect
you from an electrical shock. Please consult your local electrical authority or
qualifi ed electronic technician for more details.

Switchbone V2
The Switchbone V2 power booster is activated by depressing the right
BOOST footswitch. This works in conjunction with a 3-position footswitch
SELECT switch, a variable clean boost control and a mid boost control.
To use the clean boost, set the 3-position switch in the bottom to GAIN
and adjust the boost level to suit. This is able to deliver up to +18dB of
pure, Class-A clean gain. Setting the select to the top +MID position lets
you then add more mid-range to your solos. This is particularly effective
at increasing sustain or fattening up single coil pickups.
When the SELECT switch is moved to the middle MUTE position, the two
boost circuits are disabled and boost footswitch will mute the amplifi er
outputs for quiet on-stage tuning. It should be noted that the tuner output
is always on. This allows quick checks in between songs.
+ MID: Mid boost and gain boost. This is the
most often used setting. This allows both gain
and mid to be boosted as needed. Simply adjust
the boost level and away you go.
MUTE: Disengages the boost function and turns
this into a mute switch. This allows you to moni-
tor the tuner output without having any sound
pass through to the output of the Switchbone
V2. Be careful! This is usually the fi rst place to
look if you are not getting any sound out of your
Switchbone V2!
GAIN: This bypasses the MID function and
directs the signal through a GAIN boost. The
gain boost is used to increase sustain for soloing.
