When using both output jacks to provide multiple speakers for a given channel, it is important to ensure that the combination of speaker impedances for the given Velocity 100 output channel does not equate to a combined impedance of 2 or less. 3 POWER module This module provides a connection for the power cord and also houses the main fuse of the unit. (For information about changing the fuse, please see page 5. ) OUTPUTS jacks (Ch. 1): These ¼" mono jacks provide outputs for Channel 1 to speaker cabinets. These jacks are configured in parallel. 4 Important!Do not use these outputs with loads of 2 or less. When using both output jacks to provide multiple speakers for a given channel, it is important to ensure that the combination of speaker impedances for the given Velocity 100 output channel does not equate to a combined impedance of 2 or less. 5 IN jack (Ch. 1): This ¼" jack provides an input to Channel 1 from the output of a preamp or the device in an effects chain. 3 Connections Stereo Applications 4 Operating Precautions Although operation of the Velocity 100 is simple once the proper connections have been made, attention to the following precautions is essential to protect your equipment against failure and ensure the long life of your Velocity® amplifier. ! The Velocity 100 is capable of producing the following power output levels into each of these loads: 55 watts @ 4 40 watts @ 8 28 watts @ 16 Always be certain to use speakers or speaker cabinets capable of withstanding the power provided for the above loads. Rocktron is not responsible for speaker failure resulting from the use of this equipment. ! [. . . ] Rocktron is not responsible for speaker failure resulting from the use of this equipment. !! Never connect 2 outputs of the amplifier to the same speaker. This would be equivalent to shorting the outputs of the amplifier together and would shut the unit down immediately. When plugging and unplugging speaker outputs, shut the amplifier OFF to avoid over-current shutdown of the unit. 5 Fuse Replacement Always replace the main fuse with an identically rated replacement.
