CONNECTING YOUR E-SUB(S)
Line Inputs
e E-Sub features individual, le and right, unbalanced RCA-type
input connectors. ese are the most commonly used connectors for home
audio applications.
For systems with a mono subwoofer or “LFE” channel connection, only one
RCA-type jack will be used (Le or Right). is method applies to most modern
multi-channel receivers and preamplier / processors.
Separate le and right RCA-type input jacks are provided for systems without
a dedicated mono subwoofer connection. is typically applies to two-channel
audio equipment. In a two-channel application, you must supply separate le and
right inputs to a single E-Sub in order to have high-pass ltered, stereo outputs
from its Line Outputs. e E-Sub will automatically sum the le and right inputs
to feed its internal subwoofer amplier.
RCA-type connectors (one for each channel):
Tip: Positive
Sleeve: Negative
Input Impedance: 10 kΩ
“Grounded / Isolated” Switch
is feature is included to deal with the signal grounding issues oen
encountered in home theater systems when several components from dierent
manufacturers are interconnected. e “Grounded / Isolated” Input Mode switch
on the rear connection panel alters only the “Line Inputs” and is designed to
facilitate a quiet, hum-free connection to your audio or home theater system. is
switch has no eect on signals connected to the “High-Level Inputs”.
e E-Sub ships with this switch in the “Isolated” position. If, with all system
components connected and turned on (but no source material playing), you
hear a continuous low-frequency hum through your E-Sub, ip this switch to the
“Grounded” position and evaluate the dierence in the noise level. Use whichever
switch position provides the least hum or noise.
High Level Inputs
is feature is included for convenience when needing to connect the E-Sub
to a receiver or integrated amplier that only oers speaker level outputs. It is not
the preferred method when a line-level signal is available.
To use the “High Level Inputs” feature, simply connect the speaker outputs of
the receiver or integrated amplier to the “High Level Input” plug of the E-Sub, in
parallel with the main speakers. e main speakers will remain full-range in this
application and their sound will not be aected by the connection to the E-Sub.
e “High Level Input” consists of an input connector and removable plug
with captured-wire receptacles. Standard speaker cable, up to 12 AWG (3 mm
2
),
can be used and connected to the removable plug by backing out each set screw,
inserting the bared end of each speaker wire, taking care not to short any wire to
another, and tightening the set screw. Connections are as follows:
“High Level Input” Connector (from le to right):
1: Right Channel Negative
2: Right Channel Positive
3: Le Channel Negative
4: Le Channel Positive
Input Impedance: 4.3 kΩ
e Le and Right inputs on the E-Sub are
internally summed to a single mono channel.
