Through my years of playing, experimentation and searchin g for that great
guitar tone, I pioneered the use of the guitar subwoofer. The VECTOR 210
continues that tradition of an active guita r subwoofer designed to enhance
and expand your guit a r to ne. The VECTOR 210 is designed to be used with
your existing guitar rig with either a line level input or connected to the
speaker output of your guitar amplifi er and add that extra impact a nd huge
bottom end that you can only get by using a subwoofer. Enjoy this new
dimension of your guitar sound.

IMPORTANT SAFTEY INSTRUCTIONS
Please read the fo llowing very care fully before operating this unit
• READ ALL INSTRUC TIONS CAREFULLY BE FORE OPERATING THIS UNI T. Keep these instructions
for future reference. Heed all warnings and follow all instructions.
• Do not use this unit near water, in the rain, or where there is moisture. If this warning is
ignored a serious electrical shock or death may occur.
• Do not attempt to service this unit. No user serviceable parts inside. Refer servicing to
qualified, ISP approved personnel. Servicing is required when the unit is damaged in any way,
such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into
the unit, the unit has been exposed to rain or moist ure, does not operat e normally, or has been
dropped.
• Do not block any ventilation openings on the unit. Do not install near heat sources such as
radiators, heat registers, stoves, or other apparatus that produces heat.
• Do not defeat the grounding pin on the power pl ug. A grounding type plug has two blades and
a third grounding prong. If the grounded plug does not fit in your outlet, please consult an
electrician for replacement of the outlet, which may be obsolete.
• Care should be taken to avoid getting any foreign objects or liquid into this unit. Avoid e xp os ur e
of this equipment to dripping or splashing and ens ure that no objects filled with liqui d, such as
vases, are placed on the equipment.
• Only use accessories or attachments that are specified by the manufacturer.

manufacturer, or sold as an accessory with the unit. When a caster attachment is used, use
caution when moving the cart/apparatus combination to avoid injury from tipping over.
• To completely disconnect this unit from the AC mains, d isconnect the power supply cord plug
from the AC receptacle.
• This active speaker system has internal power amplifier(s) and a heats ink located internally with
cooling ports on the back of the unit for airflow over the heatsink. Care should be taken to avoid
placing this active speaker in a location where the airflow is impeded.
• Do not drive t he unit into excessive heavy distortion for an extended period of time to avoid
premature speaker failure.

POWER REQUIREMENTS
This unit requir es connecti on to a 120 volt AC outl et. Do not c ut or di sconnect the
ground pin on the power cord. Do not attempt t o connect this unit to any power
source other than the specified 120VAC. The VECTOR 210 will typically draw
approximately 4 amps of current when driven hard.
CAUTION
Most tube ampli fiers require a load on the output to avoid damage to the
amplifiers output transformer. Mak e sure yo u co nne ct an e x ternal s peaker

damage to any tube amplifier.
VECTOR 210 CONCEPT
The VECTOR 210 was designed for ease of use. There are two possible ways to
connect and use the VECTOR 210 Powered Subwoofer. You can use the VECTOR
210 at either line level or connected directly to the speaker output of any guitar
amplifier. Make sure to select the correct input attenuator switch setting based on
line level use or speaker level use. In speaker level, connect the speaker output of
the guitar amplifier to the input of the VECTOR 210 like you would any other
speaker cabinet and confirm the correct setting of the input attenuator switch on
the back panel is set for Speaker level. NOTE: As stated a bove, the VECTOR
210 does not provide any load on the output of the amplifier. It is a v ery
high impedance load greater than 150,000 ohms. Most Tube amplifiers
require a proper load on the output to avoid damage to the output
transformer. Make sure to connect an appropriate speaker load when
using the VECTOR 210 connected at speaker level output to a Tube
amplifier. The VECTOR 210 can also be used in line level by feeding a line level
input signal to the input of the VECTOR 210 and selecting the line level setting of
the input attenuator switch. This allows the VECTOR 210 to work directly with any
pedal chain or even connect ed to the send output of a guit ar amplifier. The input
signal is attenuated to the correct level, low pass filtered, and then re-amplified
internally. The subwoofer level is adjustable via the sub level control on the back
of the VECTOR 210 cabinet. The internal 400-WATT RMS Active D-CAT amplifier
drives dual 10-inch subwoofer speakers and delivers 120Hz and below sub
frequencies for deep, low e nd punch. The VECTOR 210 Cabinet is flat all the way
down to approximately 45Hz delivering enough low-end bass to match the
frequency response of even 7 string guitars. Tune down as far as you want and the
VECTOR 210 continues to perform. The VECTOR 210’s internal D-CAT amplifier has
global thermal protection, thermal protection built in the power transformer, and
an on board distortion limiter circuit to eliminate the possibility of feeding square
waves to the woofer. This means that, as long and hard as you drive t he VECTOR
210, even to its maximum limits, you never have t o worry about fai lures. Whet her
you use a line level input or a guitar amplifier speaker level input, the VECTOR 210
adds that missing bass for the guitar rig.

Grounding Options
The VECTOR 210 is designed to allow interconnection to all makes and
models of amplifiers available including amplifiers with Bridge Mode
operation. A Bridge Mode ampli fier design offers higher output sig nal swing
because one channel drives the positive t erminal of a speake r in phase and a
second channel drives the negative terminal of the speaker with an i nverted
signal. In order to accept connection with Bridge Mode amplifiers the
VECTOR 210 input circuit is a true differential floating input. The picture
below shows the connect ion betwee n a differential Bridge Mode amplifier and
the floating Differential Input circuit of the VECTOR 210.
There is not a common ground c onnection as there would be with a sing leended input connection. In most applications, the ground pin on the AC
power cable will provide a common ground between the two units.
To ensure safety, it is important to never cut or remove the ground pin on a
power cable and be sure every unit is connected to a common ground in the
system.
If, however, the amplifier is floating with respect to power ground and the
pre-amplifier or pedals used are also floating and do no t provide a co nnect i on
to power ground, a ground buzz can occur. This ground buzz can be
eliminated by connecti ng a ground wire between the rear panel ground tab
and the ground of the input circui t or pre ampli fier. If you ar e uncl ear on ho w
to make this connection or have questions, contact ISP directly for more
details.
NOTE: The VECTOR 210 provides automatic protection against
connecting a speaker level input signal with the Attenuation Switch
set in line level position. If the input signal exceeds the maximum
line level of +20dbu, the VECTOR 210 will attenuate and mute the
output signal to avoid damaging the internal amplifier or s peaker. If
this happens, switch the Input Attenuator switch to the Speaker
Input setting and the VECTOR 210 will operate after a 20 second
mute time pe r iod.
LINE LEVEL SYSTEM CONNECTIONS
NOTE: THE VECTOR 210 can also be connected to the send output of a guitar head
for a line level input. Make sure to set the Input Attenuator switch for Line Input

SPEAKER LEVEL SYSTEM CONNECTIONS
When using the Vector 210 with a tube guitar amplifier and connected to the
speaker output, it is possible to have a micro-phonic feedback occur due to the fact
that the 4x12 speaker cabinet can act li ke a micropho ne on the inp ut of the Ve ctor
210. This can cause a low freq uency h o wl (feedback) due to the fact that the tube
amplifier has relatively high output impedance. This high output impedance is
because the tube amplifier uses an output-coupling transformer to match the
impedance of the speaker with the correct output tap on the o utput transformer.
The lower the impedance of t he speaker being driven, the less chance for this type
of feedback to occur, but there are a number of things that can be done to
eliminate this probl em .
1. Reduce the output level of the Vector 210, which will reduce the gain
between the 4x12 speakers and the output of the Vector 210.
2. Move the location of the subwoofer away from the 4x12 cabinet.
3. Use a lower impedance cabinet to reduce the impedance drive from the head.
