Front Panel
LEVEL Control (Channel 1/Ch.1): When used in stereo (two inputs into Ch.1 and
Ch.2 on the back of the unit) this control determines the volume level for Channel 1
output only. When used in MONO (one input into Ch.1 input on the back of the unit)
this control determines the volume level of both Ch.1 and Ch.2 outputs.
RESONANCE Control (Channel 1/Ch.1): This control "beefs up" the lower range
giving the Velocity 100LTD extra performance at the low-end of the sonic spectrum.
When used in stereo (two inputs into Ch.1 and Ch.2 on the back of the unit) this
control determines the amount of RESONANCE for Channel 1 only. When used in
MONO (one input into Ch.1 input on the back of the unit) this control determines the
RESONANCE of both Ch.1 and Ch.2 outputs.
PRESENCE Control (Channel 1/Ch.1): This control opens up the treble and higher
end, offering more "voice" for solo playing. When used in stereo (two inputs into Ch.1
and Ch.2 on the back of the unit) this control determines the amount of PRESENCE
for Channel 1 only. When used in MONO (one input into Ch.1 input on the back of
the unit) this control determines the PRESENCE of both Ch.1 and Ch.2 outputs.
LEVEL Control (Channel 2/Ch.2): This control determines the volume level for
Channel 2.
RESONANCE Control (Channel 2/Ch.2): This control determines the amount of
RESONANCE for Channel 2. This control "beefs up" the lower range giving the
Velocity 100LTD extra performance at the low-end of the sonic spectrum.
PRESENCE Control (Channel 2/Ch.2): This control determines the PRESENCE
for Channel 2. This control opens up the treble and higher end, offering more "voice"
for solo playing.
POWER LED: This is the "POWER" LED. When the Velocity 100LTD is "ON" the
LED will be lit or "ON".
POWER SWITCH: This switch powers up the Velocity 100LTD.

Rear Panel
POWER Module This module provides a connection for the power cord
and also houses the main fuse of the unit. (For more information about the
changing the fuse, please see page 5)
OUTPUTS jacks (Ch. 2): These ¼" mono jacks provide outputs for
Channel 2 to speaker cabinets. These jacks are congured in parallel.
Important!
Do not use these outputs with loads of 2 Ohms 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 100LTD output channel does not equate
to a combined impedance of 2 Ohms or less.
INPUT jack (Ch.2): This ¼" jack provides an input to Channel 2 from the
output of a preamp or the device in an effects chain.
OUTPUT jacks (Ch. 1): These 1/4" mono jacks provide outputs for
Channel 1 to speaker cabinets. These jacks are congured in parallel.
Important!
Do not use these outputs with loads of 2 Ohms 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 100LTD output channel does not equate
to a combined impedance of 2 Ohms or less.
INPUT jack (Ch. 1 MONO): This ¼" jack provides an input to Channel
1 from the output of a preamp or the device in an effects chain. Use this
input if running in MONO. If the Channel 2 input jack is not used, then
the signal from the Input jack (Ch.1) will be sent to both Output jacks
(Ch.1 & Ch.2).

Operating Precautions
Although operation of the Velocity 100LTD 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® amplier.
The Velocity 100LTD is capable of producing the following power output levels
into each of these loads:
55 watts @ 4Ω
40 watts @ 8Ω
28 watts @ 16Ω
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.
Never connect 2 outputs of the amplier to the same speaker. This would be
equivalent to shorting the outputs of the amplier together and would shut the unit
down immediately.
When plugging and unplugging speaker outputs, shut the amplier OFF to avoid
over-current shutdown of the unit.

Fuse Replacement
Always replace the main fuse with an identically rated replacement. Your Velocity 100LTD am-
plier uses a 5x20mm, (4A amp, 250V slow-blow fuse 118VAC) (2A, 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.
Use a small at screwdriver as shown to slide the fuse cover out from the power inlet module. The
fuse can be found inside the fuse cover module after it is pulled out.

Note: A small compartment is
also provided within the fuse
cover module for storing a
spare fuse.
After replacing the fuse with another of identical specications, push the fuse cover module fully back
into place, ensuring that the fuse has snapped onto the fuse holder inside the power inlet module.

Note: The Velocity 100 LTD does not have a switching power supply. Therefore, it can only be used in places
where the voltage matches the unit. We offer three versions:
100V for Japan
117V for USA (110V)
220-240 for Europe.
DO NOT USE THE VELOCITY 100 LTD WHERE THE VOLTAGE DOES NOT MATCH THE SPECIFICA-
