CHAPTER 1

DRAWMER

1976 STEREO 3 BAND SATURATION AND WIDTH PROCESSOR

INTRODUCTION

The 1976 3 band stereo saturation and width processor has been designed to inject character, colour & life into your
recordings and live sound in a style endemic of the classic equipment of the 1970's. The completely analogue saturation
of the 1976 will provide the realism that plug-ins can only aspire to, replacing the harsh, sterile digital sound with
fullness, softness and warmth. Why emulate saturation when you can have the real thing?

Inspired by the highly acclaimed saturation and width features of our DC2476 Digital Mastering Processor the 3 bands
of independent saturation of the 1976 have been designed to add the pleasing imperfections that are so endemic in
classic gear. Saturation is ideal for adding fullness to your music, taking your music from a cold, bleak landscape to a
warm, bright vista. In addition, however, unlike conventional saturation products the 1976 also features 3 bands of stereo
width control to really bring out the depth and add real presence to your mix, and all with a single, yet comprehensive
set of controls that provide genuine stereo operation.

What is saturation? Saturation in music production is something that can really enrich the sound in your mix by
adding a subtle form of distortion that adds pleasant-sounding harmonics. It originates from the analog days when audio
recordings ran through various pieces of hardware, each one adding their own character to the music giving the audio a
pleasant quality that was much sought after. Today, in the digital age, these characteristics no longer occur naturally,
giving an overly clean, sterile quality to the audio, with saturation plug-ins used to emulate those not present. The 1976
allows you to add this character in a completely analogue, natural way. However, it's use is not only limited to digital
recordings, it'll add presence, warmth and life to any audio regardless of how it's recorded, whether its drum, vocals,
synths and more, in digital or analogue.

What about 3 Band Saturation? Because the 1976 as 3 bands of independent saturation it can pull off amazing feats
that single-band saturation could never accomplish. For example, it can bring out the bassline, adding presence and
grit without ruining the overall balance within the mix by adding distortion to the top end. Or enhance the vocals without
making the bottom sound muddy.

What about Width? Without stereo widening the mix won't jump out of the speaker and grab your listener, this is
where the 3 bands of the 1976 can be used to enhance the extra dimension to take the mix from a flat wall of sound to
a 3D immersive experience. It's likely your mix will have a stereo element already, however, the 1976 makes it super
easy to control these, widening and monogising where necessary to get the desired effect, and all just using the single
stereo controls of the low, mid and high bands. One major benefit of having independent width control for each of the
bands is to allow the high frequencies to be spread across a wider soundstage without affecting the low frequency end.

The key features are as follows:

Powerful 3 Band all Analogue Saturation for adding warmth to both your digital and analogue sounds.

Designed to Inject Character to your audio reminiscent of 1970's era gear and remove the sanitized
harshness that digital recordings suffer from.

3 band fully adjustable Stereo Width provides controllable depth and presence to you mix.

Fully Variable Crossover controls between the bands allows you to tune in to signals for different
amounts of independent saturation across the full frequency range.

Genuine stereo operation with one set of controls for both channels.

Can operate in Stereo and Mono.

The Mono switch helps highlight problems within the stereo mix.

Internal Low Hum Toroidal Linear Power Supply with Voltage Selector Switch.

Classic Drawmer Build Quality with Rugged Steel Chassis and Alluminium Front Panel.

INSTALLATION

The 1976 is designed for standard 19" rack mounting and
occupies 1U of rack space. Avoid mounting the unit directly
above power amplifiers or power supplies that radiate
significant amounts of heat and always connect the mains

earth to the unit. Fibre or plastic washers may be used to
prevent the front panel becoming marked by the mounting
bolts. It is also advisable to leave space above the unit to
allow the heat to dissipate.

POWER CONNECTION

The 1976 unit will be supplied with a power cable suitable for domestic power outlets in your country. For your own safety,
it is important that you use this cable to connect to the mains supply earth. The cable must not be tampered with or
modified.

The power supply socket has an integral fuse drawer containing the power fuse of the same value, to suit the mains
voltage for which the unit has been supplied. Removal of the drawer is only possible with the power cord removed. The
fuse should never blow under normal operation. If the fuse is suspected of having blown, then a fault will have occurred
and this fault condition should be inspected by a qualified service engineer. When replacing the fuse, always comply with
the Safety Instructions.

If the unit is to be used with a mains input operating voltage different to that for which the unit is supplied, the following
procedure must be carried out by a technically competent person, (see following diagrams)

1: Disconnect the unit from the mains.

2: Using a number 1 size pozidrive
screwdriver, remove the seven self

-tapping screws that retain the top cover. Tw
sc rews are f oun d al ong eac h
side; two along the top edge at the rear;
and the upper central screw on the front
facia panel.

3: Slide the voltage change-over switch
(S11) until the correct (or nearest) mains
input voltage is visible on the switch
actuator.
