E-Sub
Line Outputs
The E-Sub features individual, left and right, unbalanced RCA-type output
connectors to feed a second subwoofer or an amplifier powering main stereo
speakers. The “Line Outputs” can be used in two distinct ways, depending on
your system’s configuration.
Crossover On: High-Pass Filtered Outputs
When the E-Sub’s on-board crossover is engaged (“Crossover” switch in
the “on” position - page 15), the “Line Outputs” will deliver a high-pass filtered
signal according to the frequency selected by the “crossover freq. (Hz)” knob.
This creates a true, two-way, 24 dB/octave, Linkwitz-Riley crossover between the
E-Sub and the main stereo speakers.
Please note that you must supply separate left and right channel stereo inputs
to the E-Sub in order to have high-pass filtered, stereo outputs from its “Line
Outputs”. If you supply only one channel of input to the E-Sub, only the line
output corresponding to the input with signal will deliver a high-pass filtered
signal (the other line output will have no signal). If you are using two E-Subs in
a two-channel system, you can assign one E-Sub to the left stereo channel and
the other E-Sub to the right stereo channel, using only one “Line Input” and one
“Line Output” per E-sub.
Crossover Off: Pass-Through Subwoofer Output
When the E-Sub’s on-board crossover is defeated (“Crossover” switch in the
“off” position - page 15), the “Line Outputs” will deliver a pass-through, buffered
signal that is identical to the signal feeding the E-Sub’s “Line Inputs”. This is very
useful for passing a subwoofer signal from one E-Sub to another E-Sub in a multi-
subwoofer installation.
AC Power Connector
The IEC-style AC cord receptacle receives the heavy-gauge, 6 ft. (1.8 m) long,
power cord included with your E-Sub subwoofer. E-Subs sold in different parts
of the world are configured for each market’s electrical system and include
approprate plugs on their power cords. Please note the voltage markings next
to the AC Connector and make sure you are only powering the E-Sub from a
receptacle that matches these markings. Do not use any AC power cord other
than the one supplied with the E-Sub.
The E-Sub subwoofer is a very powerful device and can draw a lot of current.
If too many components are connected with an E-Sub subwoofer to one electrical
outlet, you risk tripping a household circuit breaker during very demanding
program material. If this happens, split the E-Sub and other components between
two AC electrical circuits.
