BSS Audio

Quad Compressor/De-Esser

DPR-404

The professional multi-channel dynamic

processor

In nearly every type of audio production

environment the availability of versatile

dynamic gain control has become more

or less mandatory.

An ever increasing diversity of mono

and stereo programme source types are

now being handled by higher quality

signal chains and storage media. The

benefits of accurate and creative

dynamics processing are now relevant

to a wider range of audio professionals

than ever before.

BSS answers this need with a versatile

1U package comprising four-channels

of advanced subtractive compressor /

limiter and HF de-esser facilities,

designed with the emphasis on flexibil-

ity and ease of use ... the DPR-404

4-CHANNEL COMPRESSOR DE-ESSER.

Each channel includes a variable Ratio

compressor / limiter that features our

proprietary “progressive knee” charac-

teristic. This gives soft-knee, over-easy

musicality at low Ratios, varying

gradually towards dependable, hard-

limiter precision at the maximum

setting. Threshold adjustment is

simplified by provision of an accurately

calibrated control scale and continuous

display of side-chain level up to the

threshold point. Gain Reduction

metering is also clearly integrated with

this display to provide intuitive monitor-

ing of the system’s activity in use.

Attack and Release time constants are

automatically and continually regulated

by the dynamic and harmonic content

of the programme material, and so

require virtually no attention from the

operator.

For maximum versatility, however, each

can be selected to a FAST-Auto mode,

allowing greater choice for creative

treatment of individual sources. A gain

make-up control an output Clip indica-

tor assist with normalisation of operating

levels and overload margins.

Additionally, each channel also in-

cludes an advanced but straightforward

HF De-esser. Previously only available

as a dedicated mode on the acclaimed

BSS DPR-402 dynamics processor, this

facility gives you smooth, frequency -

selective dynamic sibilance control

quickly and without unpleasant side-

effects or lisping. A dedicated two-led

display shows you the extent of the

sibilance processing, calibrated with a

helpful “enough” and “too much”

characteristic.

All this high performance processing

power is housed in a rugged 1U 19"

steel case, with high grade electronics

and hardware being supported by a

robust power supply featuring superior

line regulation and interference suppres-

sion.

If you need compact but sophisticated

dynamics processing that helps get

things done fast the choice is simple :-

DPR-404.

For over a decade, BSS have been

manufacturing professional audio

products that combine the highest levels

of performance with technical excel-

lence and proven reliability. All of this

expertise and experience is encapsu-

lated in the DPR-404 4-CHANNEL

COMPRESSOR DE-ESSER.

THRESHOLD control sets the level at

which gain reduction starts to occur.

BELOW Threshold meter displays signal

level below threshold to aid set-up.

RATIO control sets the amount of gain

reduction when signal exceeds the

threshold setting. Soft knee at low ratios,

hard limiting at maximum extremes.

GAIN REDUCTION meter displays the

degree of compressor / limiter activity

occurring, in dB’S.

CLIP LED indicates onset of channel

signal overload.

GAIN control allows the operator to

restore the compressed signal to nominal

operating levels.

LINK switch allows channels 1/2 and 3/4

to be linked as pairs for stereo operation.

ATTACK and RELEASE time constants

are automatically programme-controlled,

but may be switched between FAST and

NORMAL ranges.

DE-ESS control adjusts for the amount of

de-essing required, independent of the

compressor / limiter settings.

FREQUENCY control tunes the dynamic

HF shelf into the sibilant frequencies.
