5 mSec, 10 mSec Delay***
Proper time alignment of the system is achieved by
selecting the Bypass, 5 or 10 mSec Delay (All Pass
Phase Shifter). In conjunction with the proper subwoof-
er cutoff frequency (see tables 1 & 2), the L-Series and
the E-Series output is aligned with the Subwoofer. This
minimizes the anomalies caused by phase cancella-
tion and helps achieve the best quality sound.
Subwoofer Mode In/Out
The Subwoofer Mode push-button enables (IN posi-
tion) the connection of an amplifier for driving a sub-
woofer. The processor factory presets allow one side
of a Yorkville AP4040 or A4.4 (gain range of 39 dB) to
be used for a flat frequency response. There are a
variety of subwoofers in the élite line to choose from,
contact your local Yorkville dealer for proper match-
ing of full-range cabinets with subwoofers.
When the Subwoofer Mode push-button is in the
OUT position, the cut-off frequency of the woofer(s)
are lowered to accommodate the enclosure when
using a subwoofer. It automatically optimizes subsonic
cut-off and equalization of the lower portion of the
woofer's frequency response.
Note: in either position, the Subwoofer Balanced Output of
the processor is always enabled — for applications where
applicable. Refer to figures 1 through 14 for suggested hook
ups,
Adjustable Crossover Control
The adjustable Crossover control accommodates all
of Yorkville's subwoofers by providing a variable upper
cutoff frequency optimized for the drivers (refer to cor-
responding curves for your élite processor as shown
in the Graph Section). This allows control of the cross-

shielded ground to connect the sleeves of the ¼ inch connectors. Cables with an XLR connector on one end and ¼ inch
connectors on the other should be wired as shown below:

Notes on Hum and Noise
Reduction
Over the years, designers at Yorkville have been
developing circuits that greatly reduce our products'
susceptibility to hum and buzz. These circuits require
the use of the proper balanced shielded cables to
work. Balanced ¼ inch T.R.S. to T.R.S. (Tip/Ring/Sleeve)
cables are correct for use with élite processors, XLR to
XLR for 230V versions). The processors, and most other
Yorkville products, will reject some noise even when
you are using unbalanced patch cables. To be sure
of maximum noise rejection always use balanced
cables.
What if your amplifier, or mixer, does not have
balanced inputs (or outputs)? These processors have
an exclusive Yorkville feature called Remote Ground
Reference. This feature provides the noise rejection
approaching a balanced circuit (even when the unit
at the other end is unbalanced). In many cases, using
a balanced (T.R.S. ¼ inch) cable will work, if it doesn't,
try the following... Assuming the mixer or power ampli-
fier has mono ¼ inch jacks, rig a custom balanced
patch cable by replacing the T.R.S. plug on one
end (not the Yorkville processor end) with a regular
mono1/4 inch phone plug. Connect the hot (from tip
of T.R.S. or pin 2 of XLR) to the tip of the mono plug.
Now twist the unused center lead (from ring of T.R.S.
or XLR pin 3) and the ground shield together (solder
them to the phone plug's ground lug. Identify the
cable with tape on the plug that has been modified.
