INTRODUCTION

Designed to meet and exceed the needs of the recording, broadcast, installation and live sound
industries, the Klark Teknik DN 3601 Programmable Slave Graphic Equaliser is an extremely high
quality, digitally controlled, two-channel,tl1ird-octave equaliser that offers state-of-the-art audio
performance in a remote controlable, tamper-proof, cost effective package. The two channels may
eitherbeused independently or linked for stereo use. To furtherextend the flexibility of the equaliser,
the unit also incorporates variable frequency low and high-pass filters, two notch filters with variable
frequency and depth and overall gain adjustment on each channel.

Being the slave derivative of the KlarkTeknik model DN3600, the DN 3601 front panel features only
twin signal strength meters, clip LEDs, an LED numerical display andapower switch. The unit can be
controlled by amasterDN3600 unit orby asuitably equipped computer or otherlvflDI control device.
Up to 64DN 3601 units (ormixed DN36005 andDN3601s) may be linked in a single MJDI loop via
the Pro MIDI Interface on the rear panel. The DN3601 may store up to 66 equaliser programs in its
own, internal memory and canthen takefulladvantage of the extensive user interface of thecontroling
device. A 16-pin connectoris provided on the DN 3600 foruse in conjunction with the DN 60 Real
Time Spectrum Analyser enabling room analysis andequalisation to be accomplished automatically.

An extensive equalisation system canbecreated with central, userfriendly control. Slave units maybe
addressed individually or globally by the master, andwill also respond to standard MIDI program
change cormnands.

Theproprietary analogue filters arebased around the KlarkTeknik MELT"hybrid filtercircuits which
offer far greater headroom and dynamic range than is possrble using 18-bit linear, digital systems.
Benefiting from revised circuitry, these filters are exceptionally reliable and offer greaterstability than
discrete designs. They are also relatively immune to electromagnetic interference, unlike coil-based
filters. Separate supplyrails areusedforthe digital and analogue circuitry which, incombination with
rigorous internal screening, ensures the cleanest possible audio signal path.

lnordertoprovidemaximumoperational flexibility, the systemincludm a switchable Qmode. 'IheLow
Q setting (Q2360) provides an accurate emulation of the industry-standard DN360equaliser. InHigh
Q mode (Qz27), the performance emulates the DN27.

To maintain the optimum signal to noise ratio andheadroomatall equaliser settings, the gaincontml acts
on the equaliser sections themselves rather than being asimple pre or post-equalisation gain stage.
Additionally, an Auto gain mode is included in the system which automatically scales the gain of the
individual equaliser bands as cut or boost is applied to reduce the risk of accidental clipping and to
maintain a safe workingheadroom.

Boththe input and output circuitry is electronically balanced with anominal operating level of +4dBu.

The output circuitryis based ontheMidas X13 output stage, giving exceptionally high drive capability.
A transformer option is available for both inputs and outputs.
