BRIDGE MODE

Bridge mode is used when we do not have a large enough amplifier
for the speaker being used, and is similar to summing both channels
into a single one. It is only available on models E-8, E-12 and E-20.
The Appendix has information on how to enable this mode of
operation.

STEREO MODE

This is the default mode when the unit is unpacked. The signal
plugged into channel A feeds channel A, and the signal plugged into
channel B feeds channel B.

PARALLEL MODE

Available only on models E-8, E-12 and E-20, this mode is useful
when the same signal is wanted for both channels. The signal

the amps unless a similar filter is located somewhere else in the
system chain (for instance at an active crossover filter).
For systems with large (18", 15") subwoofer reinforcement and for
large full range systems, use the 35 Hz position.
For smaller full range systems (12", 8") the 60 Hz cut-off frequency
is recommended.
LIMITERS
We have warned elsewhere in this manual against prolonged
amplifier clip, because of the danger of speaker damage.
The limiters built into models E-8, E-12 and E-20 help maintain
signal peaks under control and avoid excessive amplifier clip. We
recommend that you activate the limiter on both channels of the
amplifier, specially if the system is used by an inexperienced
operator or one with a tendency to drive the system over its limits.
plugged into channel A is passed along to channel B,
so that both channels are fed with a single input,
without the need of an external patch cable. Although
the signal will be identical on both channels as
derived from the input to channel A, each channel's
volume control remains active.

HIGH-PASS (SUBSONIC) FILTER

(Models E-8, E-12 and E-20 only)
It is good recommended practice to use a high-pass
filter with a cut-off frequency close to the speaker's
lowest operating point. This way we avoid problems
derived from excess excursion ("bottoming out")
when trying the reproduce frequencies that go
beyond a system's band-pass, and we are able to use
put that power to use, instead of it going to waste.
Thus, appropriate high-pass filtering maximises
acoustic power and makes systems more reliable.
We recommend enabling the high-pass filter built into
