'This is the Rolls Royce of mixers' - DJ Mag
Optional Bakelite knobs shown. Available at an additional cost of £96 GBP. Standard knobs are black with silver tops.
The mixer is designed to the highest audio standard featuring a valve stage giving extra warmth and depth to the sound and is designed for professional DJs, clubs and venues. It is loaded with features to enhance the DJs performance and sound.
An audiophile upgrade is now available which comprises of upgraded capacitors and op-amps providing a small but measureable perfomance increase.
Each of the channels is equipped with a standard 3 band eq with +/- 15db of gain at specially selected musical frequencies.
A five times gain control and five point LED meters on each input channel allow for precise matching of input signal levels and smooth Blue Velvet rotary faders ensure a perfect mix. Individual channels can be routed either side using the rotary cross fader.
The DN78 is also equipped with a very powerful Isolator on the output giving +8db of boost and total cut of three carefully selected frequencies. There is also a control to select the mid frequency range offering further cut of the lower end of that range up to the higher end. These filters have a wide Q range to ensure they cover the full spectrum of audio.
There are two high grade phono stage preamplifiers with standard RIAA EQ to ensure faithful full range reproduction from a standard MM record cartridge. These can also be switched to line input levels for convenience.
Uniquely offered on our rotary mixer is a high quality 32bit/384khz four channel sound card built in to the DN78 Phantom Valve enabling easy integration with digital media. The USB interface can be used for playback from most popular DJ software platforms on both Mac and Windows PC.
A high quality MIC channel with a single gain control on the back panel gives up to 56db of gain and feeds the signal over the stereo mix.
FX Send & Return
There is also a stereo effects send and return which allows a pre-isolator signal to be fed into an external effects unit and a stereo return to be fed post Isolator. Both have individual levels controllable from the front panel. The effects return can also be used as an additional stereo source input for line level signals.
A powerful headphone amp ensures more than adequate monitor levels for all types of headphones with separate cue/mix cross fader to check your output mix.
Master & Booth
Finally there is a master section with a powerful 4 way output and separate booth and master level controls. Both outputs feed RCA outputs and full balanced outputs designed for driving long lines, giving more than adequate levels to drive almost any amplifier set up.
Professional stereo analogue VU meters display master output levels. They offer a more precise indication of level than LED meters with -20 to +6db range. A clip level indicator helps to ensure the sound remains clear.
Black Fluted Silver Center knobs, 16mm, 27mm, 33mm provide accurate level control. (Please note that the images show the vintage RCA Viz knobs which are available at additional cost - see product options.)
All our potentiometers are made by ALPS, a company established in 1948 from Japan. The smooth feeling of these potentiometers make the DN78 mixer a pleasure to operate and give precise control.
