Jensen EHT-707 User Manual

Your JENSEN EHT-707 is

An extremely Powerful Active Subwoofer
with a fast, Heavy Duty 10” “ monster” driver
powered by an on-board 160 Watt RMS amplifier.

Sit-on-Floor or build-into-Cabinet: With different room positioning, Bass

response can vary as Subwoofer frequencies are mainly non-directional. This being the case Sit
On Floor can locate anywhere in the room - on display or even behind the couch, If building
into Cabinet, sitting on floor with cabinet built around your EHT-707 around will provide best
results and avoid cabinet vibration, otherwise be sure to allow for these following clearances.

Subwoofer amplifier features.

LED on front panel is Purple when active and Red when on standby. Standby mode, like on

a TV draws next to no power.

Tips

On/Off/Auto switch Leaving your EHT-707 ON permanently will remain ON and

continue to draw power (PURPLE). Switch to OFF when not
using for long periods or when on holidays (RED). We
recommend switching to AUTO so your EHT-707 will
automatically activate and perform when incoming signal
is sensed (PURPLE) then revert to standby (RED) when
signal is ceased. It is not uncommon to take between 15 and
40 minutes for LED to revert to RED from PURPLE. AUTO can be left on indefinitely.

Phase Control Switch Set to ensure the EHT-707 woofer is “in phase” with all other

woofers operating together in the same room so that Bass cancellation does not occur. Once
your entire speaker system is completely set-up, flick this switch from “ NOR” to “REV” and

leave on setting that provides the most Bass. This will be the best setting and be correctly “in

phase”. Leave switch on “ NOR” if no audible increase is detected.

Level Control Knob Advance this Volume control to harmonize your EHT-707 with Front

/ Center speakers etc. DO NOT set this on maximum. Setting too high may overload your EHT­707 causing damage. (see below setting recommendations).

Frequency Control Knob. This control adjusts how low (in frequency) you wish your

EHT-707 to operate at. In other words, 70 Hz is a lower and deeper frequency than 90Hz, so if
you set at 70Hz you will be amplifying all music information 70Hz and below this frequency
and filtering out everything above which is the intention of a Powered Subwoofer. Take care not
to advance this control too far as overloading may occur (see below recommendations).

Line Output sockets are provided for adding additional EHT-707’s using an additional

1RCA to 1 RCA lead. You may add as many EHT-707’s as you like (see page 3).

Connections.

Option A. Using with AV Receiver in 5.1, 6.1, 7.1 etc.

Connect a 1 RCA to 1 RCA lead
(not supplied) from SUB-OUT
on your AV receiver to
either L or R“ LOW
LEVEL INPUT”
on EHT-707.
Connecting to
either “L” or
“R” makes no
difference as
these are internally
paralleled.
