And, because it is a variable control, you can customize your Velocity 250 to sound like any of your favorite tube amps. Best of all, this feature is available in the mono bridged mode too! In addition, the Velocity 250 has "Definition"...
Designers have been working at creating solid state amplifiers which sound like tube amplifiers ever since the transistor hit the scene. We at Rocktron first produced the Velocity 150 & 300 amplifiers with that goal in mind. The Velocity 250 takes what those first models provided to a whole new level.
Definition circuit, while turning it fully clockwise provides maximum Definition. When switched to "BRIDGED" the Velocity 250 operates as a mono unit with increased output power (Channel 2 becomes inoperable in this condition). In the "STEREO" position the unit operates as a normal stereo amplifier.
This standard ¼" jack provides an input to Channel 1 from the output of your preamp or the last device in your effects chain. This jack is used as the input jack when operating the Velocity 250 in "bridged" mode.
* 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.
Fuse Replacement Always replace the main fuse with an identically rated replacement. Your Velocity 250 amplifier uses a 5x20mm, 5A amp, 250V slow-blow fuse (2.5A, 250V slow-blow for 230VAC). The fuse is located immediately below the line cord inlet on the rear panel and can be accessed by removing the fuse cover module as shown below.
Detection circuitry. Typically, shorting the outputs of a high output power amplifier will cause amplifier failure and severely damage internal components. The Automatic Short Detection circuit in the Velocity 250 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.
