Introduction

Unity™ speaker systems have been designed to answer a variety of demands from projecting live music to
accurately reproducing recorded program music. The Unity™ dual channel processor is an essential compo­nent to help you achieve this. It optimizes the performance of the Unity™ enclosures by performing a variety
of functions such as proper crossover points, equalization, subsonic protection and hum rejection. The dual
channel processor is placed in-between your audio source and the power amplifier. The processing should
be done just prior to the amplification stage. Its output jacks should be connected to separate amplifiers, or
amplifier channels, to power each cabinet. Crossover points for the full-range and bi-ampable enclosures
have been factory optimized (table 1 page 3). A user-adjustable Subwoofer Crossover frequency control is
provided. Suggested settings are listed on table 2 (page 3), as well as provided by a label located on the side
of the Unity™ dual channel processor. In Full-Range mode the signal to the amplifier is provided by the Low fre­quency output only. Switches select between Live/Playback, Bi-amp/Full-Range and Subwoofer In/Out modes.
Connections are made via balanced T.R.S. ¼ inch phone jacks in the 120V models or XLR for 230V models. XLR
versions can be custom-ordered on the 120V version.

Live/Playback Push-Button

The Live preset position increases the presence in
the vocal region by controlling the boost around 1.8
kHz. The Playback position is used for pre-recorded
tracks and provides a flat frequency response.
The differences in performance are subtle; either
setting will work for both functions — i.e. you’re
not required to change settings when going from
recorded program to live program.

Bi-Amp/Full Range Push-button

The Bi-Amp mode turns the Unity™ dual channel pro­cessor into an active crossover. The signals driving the
power amplifiers are optimized for the appropriate
level for the horn and low frequency driver(s). Two
amplifiers are required to drive two-way enclosures.
The U15 and U215 require passive crossovers between
the HF and MF drivers even when operating in the
bi-amp mode. Since this crossover network and the
associated attenuator circuitry remain in place in the
bi-amp mode, the required amplifier for the horn will
be larger than expected. The AP2020 in 4-ohm mode
(400 watts into 8-ohms) will give a proper flat response
and sufficient power to match with the woofers. The
AP4040 (750 watts into 8-ohms) may be more appro­priate for applications requiring strong mid/high out­put. This will put the network and drivers at their maxi­mum power handling. If the AP4040 is used the cor­rect level control setting would be 6 clicks back from
full gain. The woofer’s level has been preset for use
with an individual one side of an amplifier, with a gain
range of 36 dB (e.g. a Yorkville AP4040 or a Yorkville
A4.4). Following these guidelines ensures your system
will have a flat frequency response. The bi-ampable
Unity™ enclosure must also be configured for bi-amp
operation. (See figures 3 and 4.)

Full Range Output

The Full Range mode enhances low frequency
response and allows the cabinet’s internal passive
crossover to operate. If the Full Range mode is select­ed, the Low frequency outputs of the processor are
used to supply the optimized full range signal, and
should be connected directly to the amplifier’s inputs.
Only one amplifier will be required to drive the enclo­sure. The bi-ampable Unity™ enclosure must also be
set to the Full-Range position for full-range operation.

Note: These examples of system setups do not mention
subwoofers. The addition of a subwoofer to the system will
require additional power amplifiers.

A.P.P.S.

Bypass / 5 mSec Delay

Proper time alignment of the system is achieved by
correctly selecting the Delay (All Pass Phase Shifter)
switch. In conjunction with the proper subwoofer cutoff
frequency (see tables 1 & 2 on page 3), the Unity™
Series outputs are time aligned with the Subwoofer. This
minimizes the anomalies caused by phase cancellation
and helps achieve the best quality sound.

Subwoofer Mode In/Out

The Subwoofer Mode push-button enables (IN position)
the connection of an amplifier for driving a subwoofer.
As an example, the processor factory presets allow one
side of a Yorkville AP4040 or A4.4 (gain range of 36 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 matching
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)
is lowered to accommodate the enclosure when not

11

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 active.

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 corresponding curves for your Unity™ processor as
shown in the Graph Section). This allows control of the
crossover point between the subwoofer and woofer.
The Crossover control can be set according to a list
located on the side of the processor and in the back
pages of manual.

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 Unity™ processors,
(XLR to XLR for 230V versions). The processors 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 ampli­fier 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.

Wiring Tip / Ring / Sleeve Cables: Balanced cables should be wired Tip/Ring/Sleeve using cable with 2 conductors plus a 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:

Tip – XLR pin 2 • Ring – XLR pin 3 • Sleeve (ground) – XLR pin 1
