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.
