The New DN78 Phantom Valve is a desktop analogue DJ mixer featuring 2 dual input channels, one mono mic channel, 2 stereo USB channels and features rotary faders and a rotary cross-fader. 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 DJ’s, clubs and venues. It is laden with many features to enhance the DJ’s performance and sound. Each of the channels is equipped with a standard 3 band eq with +/- 15db of gain at specially selected musical frequency’s.


Gain

A five times gain control and five point LED meters on each input channel  allows 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.


ISO Frequency Diagram

The DN78 is also equipped with a very powerful Isolator on the output giving +8db of boost and total cut of three carefully selected frequency’s.  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.


Phono Stage

There are two high grade phono stage preamplifier with standard RIAA EQ to ensure faithful full range production from a standard MM record cartridge, which can also be switched to line input levels for convenience.


USB

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 to digital media. The USB interface can be used for playback from most popular DJ software platforms on both MAC and PC.


Microphone Input

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.


Headphone

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 with both 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.


Metering

Professional Stereo VU meters display master output levels they offer a more precise indication of level  than that of led meters. Therefore we have integrated a pair of analogue VU meters -20 – +6db to show a more accurate measurement of the output level with an additional clip level indicator to ensure the sound remains clear.


Knobs

Black Fluted Knobs Silver Center, 16mm, 27mm, 33mm are very popular to provide an accurate level control. The vintage RCA Viz knob have a very classic look and very precise.


Potentiometers

All our potentiometers are made by ALPS, a company established in 1948 from Japan who are one of the most important electronic manufacturers ever. The smooth feeling of these potentiometers make the rotary performance a pleasure to operate and give precise control.
