Your Velocity 100™has been tested and complies with the following Standards and
Directives as set forth by the European Union:
Council Directive(s): 89/336/EEC ElectromagneticCompatibility
Standard(s): EN55013, EN50082-1
This means that this product has been designed to meet stringent guidelines on how
much RF energy it can emit, and that it should be immune from other sources of interfer-
ence when properly used. Improper use of this equipment could result in increased RF
emissions, which may or may not interfere with other electronic products.
To insure against this possibility, always use good shielded cables for all audio input and
output connections. Also, bundle audio cables separately from the AC power cables.
These steps will help insure compliance with the Directive(s).

Introduction
Congratulationson yourpurchase ofthe RocktronVelocity 100power amplifier!
TheVelocity100 was designedto providegreat flexibility andhigh reliability.Thissingle-
rackspaceamplifierprovides 55 wattsof power perchannel into a4ohm load, or40 watts per
channel into an 8 ohm load.
Inaddition,the amplifier incorporatesthermal protection circuitry,aswell as protection
fromovervoltage, undervoltageand anyshortstothepower supplies.
This manual will introduce you to the Velocity 100 and its features, please keep it for
futurereference.

Front Panel
1 POWERswitch/LED
When lit, the LED indicates that the Velocity 100 is powered and ready for operation.
Note:
There are no volume adjustments on the Velocity 100. To ensure speaker
life, use the output level of the unit connected to the Velocity 100's inputs
as the master volume control. Begin operation with this output level down,
then slowly bring up the volume to the desired level.

Rear Panel
1 IN 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.
2 OUTPUTS jacks (Ch. 2):
These ¼" mono jacks provide outputs for Channel 2 to speaker cabinets. These jacks are
configured in parallel.
Important!
Do not use these outputs with loads of 2Ωor 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 2Ωor 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.)
4 OUTPUTS jacks (Ch. 1):
These ¼" mono jacks provide outputs for Channel 1 to speaker cabinets. These jacks are
configured in parallel.
Important!
Do not use these outputs with loads of 2Ωor 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 2Ωor 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.

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
failureandensure the longlife of yourVelocity®amplifier.
TheVelocity100is capableofproducing thefollowingpower 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 withstand-
ingthe powerprovided forthe aboveloads.Rocktron isnot responsiblefor
speakerfailure resulting fromthe useof this equipment.
Never connect 2 outputs of the amplifier to the same speaker. This would be
equivalentto shorting theoutputs ofthe amplifier togetherand wouldshut the
unitdown immediately.
Whenplugging and unpluggingspeaker outputs,shut the amplifierOFF to
avoidover-currentshutdownofthe unit.

Fuse Replacement
Always replace the main fuse with an identically rated replacement. Your Velocity 100
amplifieruses a 5x20mm,4A amp,250V slow-blow fuse(2A, 250Vslow-blow for 230VAC).
The fuse is located immediately below the line cord inlet on the rear panel and can be ac-
cessedby removingthefuse covermodule asshown below.
Use a small flat 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.
G
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 specifications, push the fuse cover module fully
back into place, ensuring that the fuse has snapped onto the fuse holder inside the power inlet
module.
