Bergman Audio labs is a Swedish company We build handcrafted equipment for music studios.
Our greatest passion is compressors and preamps
but sometimes we also build syntheziers and other custom projects
We manufacture our own VCA's and transformers 
But also use Lundahl / Beyer / Neutrik etc
We love what we do
and have fun at work almost every day

A-57 
 The Bergman A-57 is a versatile VCA bus compressorHand built in Sweden
with carefully selected components
The heart of the compressor is the legendary DBX Gold can wich is an old school
VCA that was created in the 70's.

           Vari Mu

Class A Tube Mastering Compressor
State of the art mastering compressor

Bergman Vari-Mu Compressor

is all transformer coupled, all valve signal path topology, operating in true balanced class A mode. Lundahl transformers Both on input and output.

All valves are carefully matched to obtain lowest noise and distortion and to ensure accurate tracking when used as a stereo compressor. Capacitors and other components have also carefully selected for low noise and colouration.

The compressor is smooth and transparent and will add warmth and sparkle to any track.

Each channel is fitted with input and output attenuators and a continuously variable input level control.

A meter showing gain reduction, and the normal threshold, attack and release controls.

A further refinement to the attack control the “thump” position allows a switched modification to the side chain giving a great tool for drums and other percussive sounds.

Independent bypass switches on both channels and a stereo link switch are also fitted."

This is our take on the classic 1176 Compressor

D-57

The stereo version of 1176

 

D-57 

Attack: adjustable from 20 microseconds to 800 microseconds
The attack time is fastest when the Attack knob is in its fully counterclockwise position,
and is slowest when it is in its fully clockwise position.

Release: adjustable from 50 milliseconds to 1100 milliseconds (1.1 seconds).
The release time is fastest when the Release knob is in its fully counterclockwise position, and 
is slowest when it is in its fully clockwise position.

Ratio: 4:1, 8:1, 12:1 & 20:1

Meter Function: "Off" (Bypass Compression) "GR" (Meter shows Gain Reduction)

Link: Sums the sidechain signals to reduce the effect of a stereo signal 
losing mid focus, Enabled with switch in up position.

IO: electronically balanced input, transformer balanced output (Lundahl)

Gain: 45 dB, ± 1 dB

Frequency Response: 20 Hz to 20 kHz ± 1 dB

Signal-to-Noise Ratio: > 81 dB with input signal at threshold of limiting, over a bandwidth of 30 Hz to 18 kHz

Fuse: 500mA (slow blow)



                  CS-100

A world class tube compressor for all purposes

• EASE OF OPERATION
• “SOFT KNEE” CHARACTERISTIC
• SWITCH SELECTABLE ATTACK AND RELEASE SETTINGS
• SIDE CHAIN ACCESS
• STEREO COUPLING CAPABILITY
• BALANCED INPUT
• BALANCED OUTPUT STAGE
• HAND CRAFTED IN SWEDEN

THE CONTROLS
ATTACK SWITCH : A three position switch with fast, medium and
slow settings, which controls the time it takes
the CS-100 to respond to the input signal.

RELEASE SWITCH: Controls the time it takes the CS-100
return to unity again. A three position switch
with fast, medium and slow settings. The
release time is also effected by the program
material. The slower the release time setting,
the more the program material determines the
release time.
METER SWITCH: Allows monitoring the output level of the CS-100
or the amount of gain reduction taking
place.
BYPASS SWITCH: This is a three position switch. In the bypass
position, the CS-100 is removed from the
audio path. In the middle (or in) position, the
CS-100 is switched into the audio path. In
the left (or link) position, the stereo link signal
is connected to its back panel connector. This
allows stereo or mono operation of two units by
front panel selection.
GAIN: Sets the voltage gain of the CS-100. It
determines the output level, which can be
monitored on the meter.
GAIN REDUCTION: Sets the amount of gain reduction taking place,
and the operating point where gain reduction
begins. The higher the gain reduction, the
higher the ratio becomes.
