Operating Precautions
Operating Precautions
Although operation of the Velocity 250 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
® amplifer.
Power Output/Speaker Load
The Velocity 250 is capable of producing the following power output levels into
each of these loads:
Unbridged (Stereo)
4
Ω
load 125 watts
8
Ω
load 90 watts
16
Ω
load 50 watts
(with both channels driven)
Bridged (Mono)
4
Ω
load Not Recommended*
8
Ω
load 250 watts
16
Ω
load 170 watts
!
Always be certain to use speakers or speaker cabinets capable of
withstanding the power provided in the above mentioned applications.
Rocktron is not responsible for speaker failure resulting from 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.
!
Plug and unplug speaker outputs with the power amplifier OFF to avoid
over-current shutdown of the unit. (See page 9 for information on Automatic
Short Detection.)
* Note: Rocktron does not recommend using the Velocity 250 in bridged mode when
connected to a load of less than 8 ohms. However, using the Velocity 250 in
bridged mode with an 8 ohm load produces a higher output level (250 watts)
than would be achieved with a 4 ohm load - therefore using a 4 ohm load
would provide no additional benefits.
