superstereo 03

We already use high grade audio capacitors by WIMA® & Vishay Roederstein® which are used in all of our EQ filter circuits and between all audio stages in the mixer. Its important to have good quality ones to ensure the audio passes from each stage with as little change as possible. It will also give all EQ circuits clarity, definition and a real smoothness overall. Allot of other mixer use very standard basic capacitors which colour the sound and looses all of its space and clarity, resulting in a average acceptable sound quality. The capacitors we offer will give that extra bit of spatial depth, clarity and bass definition.  They are used in the valve, Isolator and output stages.


superstereo 02

Our Phono Stages are designed to a high standard as found in some of the best pre-amps and far superior to most mixers, so the phono stage upgrades go that extra mile and  consist of improved filter capacitors for the RIAA EQ, special JFET op-amps for greater definition and improved output capacitors.


superstereo valve 09

Once again the valve we already use is a superb sounding valve by Raytheon®, which is found in some of the best pre-amps and DAC’s in the world. It gives the sound real depth, space and warm common in valve pre-amps.  The upgrade we offer is a rare valve by GE 1960’s, 5670 Gold Audiophile probably the best sounding audio valve of its type. It does really add that bit extra special something. Its superbly defined with real spatial clarity and depth as well as giving the bass a real controlled solid warmth.


superstereo 10

We currently use the famous Alps ‘Blue Velvet’ potentiometers for channel faders and output stage. They are great quality sound accurate and have a great touch. The TKD faders are again used in some of the best audio equipment in the world and give a very precise control over the sound and are superbly built and won’t go wrong.  Again they give that bit extra in sound quality.


superstereo 08

The upgrade here is using one of the latest high-end specialist audio op-amps available. It will give a ultra low noise higher gain output and will easily drive any load. Our output stage is already good and will drive a 600ohm load with no problem as will the upgraded one.


 

superstereo 12

We can add a simple set of slide switch to the bottom of the mixer that will switch the Phono Stage sensitivity so you can use high-end moving coil cartridges with you DN78 mixer. The Line/Phono switches will be unaffected.


superstereo 11

Add more control to your effects send , simply switches each channel separately to the effects send control instead of the whole mix.
