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 EHT-
707 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

Connecting to
either “L” or
“R” makes no
difference as
these are internally
paralleled.
