Automatic Short Detection
A feature truly unique to the Velocity
®
120 is its Automatic Short Detection
circuit. Typically, shorting the outputs of a high output power amplifier will cause
amplifier failure and severely damage internal components. The A.S.D. circuit in
the Velocity
®
120 will automatically detect any shorts which may inadvertently
occur across the amplifier's outputs and immediately shut down the unit to protect
it against internal damage.
Should this condition occur, switch the unit off for approximately 10
seconds and make sure that the cords from the amplifier outputs are properly
connected. When the power is turned on again with the proper connections, the
amplifier will operate normally. It is important to note that two outputs from the
amplifier should never be connected to the same speaker, as this would be
equivalent to shorting the outputs together and will cause the unit to shut down.
In the unlikely event that the proper connections have been made and the
unit still shuts down, we strongly recommend that you first contact our Customer
Support Department at the phone or fax number shown on the back cover of this
manual before taking the unit to a dealer or repair shop for servicing.
Definition Control
It often becomes a problem when playing with other musicians that the
guitar can get "buried" under the other instruments and cannot be distinguished
easily. The front panel Definition control gives the effect of bringing the guitar out
of the cabinet so that it can be heard despite the other instruments. Although it does
not actually affect the volume of the amplifier, the Definition control can be
adjusted so that the guitar becomes more audible when playing with a band.
Turning the Definition Control fully counter-clockwise bypasses the defi-
nition circuit, while turning it fully clockwise provides maximum definition.
