SONIC ULTRAMIZER SU9920

1. INTRODUCTION

Thank you for purchasing the SONIC ULTRAMIZER SU9920.

The SU9920 is a professional signal processor used to improve

the presence and liveliness of audio signals. For signal

processing a combination of a dynamic filter and a phase delay

algorithm is used. The latter is based on psychoacoustic

principles and guarantees improved sound characteristics

without unnatural side effects. The unit works with two

independent channels, so you can selectively process stereo or

two mono signals separately from each other. Whether you

purchased the SU9920 for your studio, live sound or the stage,

the unit's sound qualities are so impressive that you'll never

again want to do without this sound enhancer when mixing.

We at BEHRINGER hope you enjoy your new acquisition.

SONIC ULTRAMIZER SU9920

2. CONTROL ELEMENTS AND CONNECTIONS

CLIP: This LED is constantly lit when the input level is too

high. If it lights up for a short period of time it is warning

you of an impending overdrive. There is a safety headroom

of 3dBu before the signal becomes distorted. The LED

should not light up.

LEDs: The four LEDs display the output level in 10dBu

steps. Regular illumination of the 0dBu LED indicates an

optimal output level.

PROCESS: With this control the portion of high-frequency

signals to be processed by the SU9920 is specified. The

MAX setting corresponds to a level boost of +12dbU at

5kHz.

LOW CONTOUR: This control adjusts the portion of low-

frequency signals to be processed by the SU9920. The

MAX setting corresponds to a level boost of +12dbU at

50kHz.

IN/OUT: With this switch signal processing is activated

and deactivated. The LED lights up in the active operating

mode.

POWER: Use the POWER switch to put the unit into

operation. The POWER switch should be in the "Off"

position when you connect the unit to the power feed

(mains).

To disconnect the unit from the mains, pull out the power plug.

When switching on the unit ensure that the power plug is easily

accessible. To mount the unit in a rack ensure that the unit can

easily be disconnected from the mains by means of a plug or an

all-pole mains switch on the back side.

Please note: Switching the POWER switch off does

not disconnect the unit completely from the mains. For

this reason you should unplug the power cord if the

unit is not going to be used for prolonged periods of

time.

2. CONTROL ELEMENTS AND CONNECTIONS

2.1 Front panel

The control elements for CHANNEL 1 and CHANNEL 2 are identical. In the following paragraphs the functions are described using

CHANNEL 1 as an example.

Figure 2.1: Control elements on the front panel

2.2 Rear panel

Figure 2.2: Control elements on the rear panel

FUSE HOLDER / IEC POWER SOCKET: The mains

connection is made via an IEC male socket. It complies

with relevant safety regulations. A suitable power cord is

included. Replace the fuse with a fuse of the same type.

OUTPUTS 1: Balanced XLR sockets and ¼" jacks - these

are used to connect amplifiers as well as further signal

processors and recording devices. The jacks and XLR

sockets can be used in parallel when two outputs are

required.

INPUTS 1: Balanced XLR sockets and ¼" jacks - these

are used to connect line-level signal sources (e.g. a mixing

console). To avoid interference only the jacks or the XLR

sockets should be used.

SERIAL NUMBER: The serial number can be found on

the back right side of the unit. It is needed for online

registration.

SONIC ULTRAMIZER SU9920

3. PRACTICAL APPLICATION

The SU9920 belongs to the group of psychoacoustic enhancers

which also includes exciters. These devices can enhance the

quality of audio signals.

In contrast to an exciter, the SONIC ULTRAMIZER does not

add any new harmonics to the signal, but rather improves the

signal quality by processing the harmonics in the original

material. Through this action the sound is changed more naturally

than it is through harmonic enhancement with an exciter.

The concept behind the SONIC ULTRAMIZER is based on the

fact that through signal modification (as is caused for example,

by equalizers and frequency filters), the original signal is

distorted. Through this the time-based sequence of the

fundamental tone and the harmonics, whose correlation is

extremely important for naturally sounding signal reproduction

via loudspeakers, is shifted. Restoring the original time-based

relationships between the fundamental tone and the harmonics

thus ideally leads to optimal reproduction of the original signal

and hence a sound which is free from unpleasant distortion.

With the SU9920 you can reproduce the original relationships

between the fundamental tone and the harmonics and

additionally boost the high and low-frequency portions

independently of each other. Through this the transparency of

the starting signal is greatly increased and a precise reproduction

of all signals over the entire frequency spectrum is obtained.

3.1 Application examples

Similarly to a compressor or a graphic equalizer, the SU9920 is

integrated into the signal path, i.e. connected in series to mix

outputs or integrated into the insert path of a mixing console.

Avoid parallel use in the Aux path, as with an effects unit, since

this mixes the original signal with the processed effect signal,

thereby considerably worsening the sound characteristics.

The best way to use the SONIC ULTRAMIZER is in a signal

chain, e.g. from keyboard to SU9920 to amplifier, as the following

application examples show.

3.1.1 Live sound

The SU9920 is ideally suited to use with live sound systems in

clubs, discos, live concerts and public performances. Here the

unit not only can considerably improve the signal quality, but

also can compensate for the inadequacies of small or weak PA

systems.

For this application the unit should be installed between the

mixing console mix output and the amplifier input. If a graphic

equalizer is also used, it should be positioned after the SU9920.

Because this application involves stereo processing, channels

1 and 2 must have the same settings. Otherwise, the original

stereo image will be distorted.

Figure 3.1: Use of the SU9920 with live sound systems

3.1.2 Studio application

In a studio environment the SONIC ULTRAMIZER is ideal for

mastering to enhance the sound of recordings. The SU9920

can lend your music the professional polish of high-quality

productions in just a few steps. Even if you primarily work with a

digital audio workstation, you can perform the final mastering

with the SU9920 and an external recorder.

For this application connect the SU9920 so that it comes before

the mastering recorder. Channels 1 and 2 must have the same

settings since this application involves stereo processing.

Otherwise, the original stereo image will be distorted.

3. PRACTICAL APPLICATION

SONIC ULTRAMIZER SU9920

Figure 3.2: The SU9920 in Studio mode

3.1.3 Stage operation with instrument amplifiers

Besides being ideal for use with stereo signals, the SONIC

ULTRAMIZER is also suitable for use with one or two individual

signals, e.g. guitars. With electric guitars it can be used in

combination with a combo amp or a separate modelling

processor-amplifier combination to give the guitar sound more

presence, fullness and punch. A similar combination with a

keyboard and an external amplifier is possible. Because the

two channels of the SU9920 work independently, even two

different mono signals can be processed.

Connect the SU9920 with the effects loop connections on your

combo amplifier if it provides for connection in insert mode, i.e.

exclusively reproduces the output signal of the SU9920 via the

loudspeaker.

If you are using a modelling processor you must connect the

processor output to the SU9920 input and route the SU9920

signal to the amplifier.

Figure 3.3: The SU9920 in use with guitar amplifiers

3.2 Basic operation

Due to the small number of control elements on the SU9920 it

is easy to learn to use it. Perform the following steps:

1) Connect the unit according to the application as described

in section 3.1.

2) Switch on all devices (amplifier and loudspeaker last) and

ensure that the IN/OUT switch on the SU9920 is

illuminated, i.e. that the unit is working and all controls are

set to 'MIN'.

First make the following settings for one channel

(channel 1 or 2) according to the input assignment.

For stereo applications choose the same settings for

the second channel as those made for the first channel.

3) Set the signal level on the device feeding the SONIC

ULTRAMIZER such that the CLIP LED on the SU9920

either does not light up at all or for a short period of time

only.

4) Turn the PROCESS control until the desired

enhancement effect in the high-frequency range is achieved

or the 0dBU LED in the level display lights up

continuously.

5) Turn the LOW CONTOUR control until the desired

enhancement effect in the low-frequency range is achieved

or the 0dBu LED in the level display lights up

continuously.

6) To compare the original and processed signals, repeatedly

press the IN/OUT button.

7) Repeat steps 4) to 6) until you are satisfied with the result.

SONIC ULTRAMIZER SU9920

4. INSTALLATION

4.1 Rack mounting

The BEHRINGER SONIC ULTRAMIZER SU9920 requires 1U

for installation in a 19-inch rack. Please make sure that you

leave around 10cm for the rear connections. For installation of

the unit in a rack please use M6 machine screws and nuts.

4.2 Audio connections

There are various ways to integrate the SU9920 into your setup.

Depending on the application you will need different connecting

cables, and these will be discussed in the following section.

4.2.1 Cabling with jack cables

To operate the SU9920 in series with other equipment, you will

need standard commercial ¼'' jack cables, often referred to as

instrument cables or patch cables.

These cables have a ¼" TS jack plug at each end. Connect the

inputs of the equipment with the corresponding outputs of each

of the other devices.

Fig. 4.1: Unbalanced 1/4" TS jack plugs

If your other equipment has balanced inputs, use a balanced

switched cable with two stereo jack plugs at the balanced outputs

of the SU9920. These cables provide a high level of security

against interference signals such as noise interference from

power cables, and they should be used for all long cable routes.

Fig. 4.2: Balanced 1/4" TRS jack plugs

Alternatively, you can use professional XLR cables with an XLR

socket on one side and an XLR plug on the other side. This

cable connection is the most reliable both electrically and

mechanically.

Figure 4.3: Balanced XLR plug

4.2.2 Connection with insert cables

Please use standard insert cables equipped with 1/4'' connectors

to connect the SONIC ULTRAMIZER to the insert path of a

mixing console. These Y cables have two 1/4" TS connectors at

one end, and one 1/4" TRS connector at the other. Connect the

plug marked "Send" to the INPUT L jack on the effects unit.

Connect the "Return" plug to the OUTPUT L jack on the device.

Connect the TRS connector to the insert jack of the channel

strip on the mixing console. Use two insert cables for stereo

sub-groups and main-mix inserts. The second cable must be

connected to the INPUT/OUTPUT R jacks of the SU9920.

Fig. 4.4: Insert cable with one ¼" TRS (tip-ring-sleeve) jack

plug on one end and two ¼" TS (tip-sleevel) jack plugs on the

other end.
