POWER REQUIREMENTS
This unit requires connection to a 120 volt AC outlet. Do not cut or disconnect the
ground pin on the power cord. Do not attempt to 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 amplifiers require a load on the output to avoid damage to the
amplifiers output transformer. Make sure you connect an external speaker
cabinet load before applying power to any tube amplifier to avoid potential
damage to the tube amplifier. This will ensure a proper load is applied to
the output of the tube amplifier. ISP will not assume responsibility for
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 above, the VECTOR
210 does not provide any load on the output of the amplifier. It is a very
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
