Speaker Level
Set the Input Level switch to Speaker if the signal is coming directly from a power amplifier,
‘powered’ mixer, or other powered source.
Note: The ES Series Powered Subwoofer may be plugged in before or after the full range enclo-
sure. The ES Series Powered Subwoofer does not alter the signal to the daisy chained enclo-
sures and will not draw any power from the host amplifier/processor driving them. Also, note that
an external crossover is not necessary when using the ES Series Powered Subwoofer.
Tip: As well as accommodating full range enclosures, the Link jacks allow many ES Series Pow-
ered Subwoofers to be connected in a string (parallel). There is no practical limit to the number
of ES Series Powered Subwoofers that may be connected together.
WARNING: Do not plug in two speaker level sources to a single ES Series Powered Subwoofer
6. Mono Blend Input Jack
The Mono Blend Input jack enables you to connect a secondary line level signal to the system
without needing to externally sum two signals (e.g. Left and Right). This is helpful when you are
adding a single ES Series Powered Subwoofer to a stereo system. By using this input for your
secondary signal, it is blended internally with the Link input but isolated to prevent interaction of
those signals.
7. Bluetooth™ Control
This control enables or disables the Bluetooth™ connection between a tablet or a smart phone
using the Yorkville App. Pressing the Bluetooth™ button for more than 4 seconds resets the ES-
Series powered subwoofer to factory settings.
Note: The Bluetooth functionality on this product is intended for control only. It does not allow for
Bluetooth audio connection
8. Protection
The ES Series Powered Subwoofers have a DSP-based circuit to prevent clipping, over power
and over excursion. At high levels the limiter will limit the gain of the ES Series Powered Sub
-
woofer and hence if the user attempts to set the subwoofer level control at a high level, the
resulting setting will be overridden by the internal protection. The level control should be set while
operating at low levels (under 10 watts). This is accomplished by turning the master volume of
the signal going to the subwoofer down to allow the balancing and setting of the bass along with
the full range speaker top in use. If the level control is set too high due to setting it at high operat
-
ing levels the input circuit will clip and the dynamics of the bass will be lost. The Red Clip indica
-
tor will signify when this occurs. This can happen without audible distortion since the filters and
limiters will suppress the distortion.
Note: At high power levels, when the limiter is operating, increasing the Subwoofer’s Level
Control will NOT increase the output.. Do NOT continue to increase this setting while operating
at high levels.
9. Stand Mounting Adapter
The ES Series Powered Subwoofers come equipped with a built-in stand mounting adapter that
can be used with Yorkville SW-Teletube accessory to support élite powered top cabinets.
WARNING: ES Series Powered Subwoofers MUST be on a flat, level surface to support the
cabinet safely. Do not use larger than the recommended top cabinets!
