ES-Series Active Subwoofers

The ES Series Subwoofers are premium quality subwoofers with integrated power amplifiers. Created as an
easy-to-setup addition to any P.A., the ES Series Powered Subwoofers will extend the bass of a typical sound
system with the least amount of complication. The ES Series Powered Subwoofers have been optimized to
operate primarily with line level signals but can optionally accept speaker level signals.

Configuration

The ES Series Powered Subwoofers may be used in several different configurations. The basic system is
a single ES Series Powered Subwoofer used for each full-range enclosure but multiple ES Series Powered
Subwoofers may also be used (with a single full-range enclosure). The ES Series Powered Subwoofers ac-
cept and combines signals from separate line level source (e.g. Stereo sources are summed). Using the Mono
Blend XLR input combines the second line level signal properly and does not affect the stereo separation of the
full-range enclosures. When used in a setup where only one signal is provided to a speaker, such as a mono
system or stereo with more than one ES Series Powered Subwoofer, you can use any of the Link jacks.

1. Input Mode Switch

The Input Mode switch is provided to select what type of input source, line level or speaker level.

Line Level Source

The line level position is for use when the ES Series Powered Subwoofer is fed a signal directly from the
line level output of a mixer. It is recommended to use balanced cables with XLR connectors or TRS ¼-inch
phone plugs (Tip, Ring, Sleeve), this will reduce the unit's sensitivity to hum and buzz.

Speaker Level Source

This switch should be set to speaker level when the ES Series Powered Subwoofer is fed from the output of
an amplifier or speaker out from a 'powered' mixer!
WARNING: Do not plug in two speaker level sources to a single ES Series Powered Subwoofer! Increasing
the Level control while in limiting will not increase the loudness and may lead to feedback when the
operating level is reduced.

2. Sub Level Control

The Sub Level control adjusts the amount of bass added to the sound system by the ES Series Powered
Subwoofer. This adjusts for the relative sensitivity of the companion full-range speakers and the desired sys-
tem frequency response. It is recommended to set the control by listening while operating at a low level and
then it should not be changed.
