Jensen QX-95 User Manual

QX-95
250 Watt Powered "Monster" Subwoofer
Congratulations on investing in one of JENSEN's finest ever
Subwoofer Systems. You will find this information invaluable
for the long term enjoyment of your QX-95.
Your JENSEN QX-95
is an integrated Active Subwoofer System with dual 10" Heavy Duty
Sub drivers powered by an on-board 250 Watt RMS amplifier. Enclosure is 25mm thick and several
internal braces are used for structural support.
Voltage setting (if applicable).
Your QX-95 has been factory set to 220/240 volts using 3.1 amp fuse. If 110 volts is required, slide
the red voltage selection switch from 240v to 110v and fit a 6 amp fuse (not supplied). Fuse
compartment and voltage switch is located at power lead input area on amplifier.
Room Placement.
Best positioning for your QX-95 is appx. 10-20cm from a wall or better
still-across a corner. This will enable the rear port to "breath" efficiently and provide maximum
"acoustic coupling" into your room i.e. more Bass. With different room positioning, Bass response
can vary as Subwoofer frequencies are mainly non-directional.
Subwoofer amplifier features.
Main Light on front panel is Blue when active and Red
when on standby (standby mode, like on a TV draws next to no power) Switch the QX-95 amplifier
switch to "AUTO" and this can be left on indefinitely as the QX-95 automatically activates when it
senses as incoming signal. Front panel LED will then turn Blue and illuminated knobs will also light
up Blue. When signal is removed, after appx. 10-20 minutes, amplifier will revert to Standby mode,
main LED will change to Red and blue lights in knobs will switch off.
QX-95 Front Panel Controls.
Volume Control Knob (TOP)
DO NOT set this on maximum. Be careful not to advance
this control too far as overload may occur causing damage to your QX-95 (see below for settings).
Frequency Control Knob (BOTTOM)
This control adjusts how low (in frequency)
you wish your QX-95 to operate at. In other words, 40 Hz is a lower and deeper frequency than 80Hz,
so by setting your control at 80Hz you will be amplifying all music information below 80 Hz and
filtering out everything above 80 Hz which is the ideal intention of a Powered Subwoofer. Take care
not to advance this control too far as overloading may occur (see below for settings).
Where should I set these Volume & Frequency Control Knobs ??
Once
you have your QX-95 positioned and connected, try experimenting with the Level and Frequency
Control knobs to suit the Volume and depth of Bass desired. Initially, for Hi-Fi listening, try
