TABLE OF CONTENTS
Thank you for choosing the Súper 8. Heritage Audio is dedicated to bringing you ´the sound of yesterday for tomorrow´.
We specialize in capturing that unique, enticing sound that everybody has fallen in love with. For years engineers,
producers and musicians have been yearning for that classic vibe. Usually the only option is to search for old, used
original equipment that is almost always in a questionable state of operation. This brings with it a whole lot of other
issues, making the experience less than desirable. Not to mention the very high prices asked for this equipment, which
makes them virtually unobtainable for the great majority. Now it´s possible to obtain that same sound with a brand new
piece that will give you all the problem-free, heavy-duty use you´ll need for years of music making history.

DESCRIPTION
The Súper 8 offers a fantastic, compact solution for when several high quality preamps and top class conversion is
needed.
Using our Class A 73 Preamp building experience we were able to fit 8 MIC/Line preamps into a sturdy 2 unit rack. All 8
are faithful to our 3 stage all Class A design with Carnhill transformers fitted at the input and the output. The first two
channels also include our high quality JFET DI as well as a fully sweepable Lo-cut filter. All 8 channels include switches for
48V, Line, Lo-cut(-3dB at 82Hz) and Phase.
There is built in analog to digital conversion available on 3 different digital formats: ADAT, AES/EBU and SPDIF with BNC
connectors for reliable word clock syncing.
Selectable sampling frequencies from 44.1kH to 192kH. Not only can the MIC/Line Preamp outputs be directly sent to the
DAC, but there also exists the possibility of choosing an alternative input, per channel, for the digital conversion, making
this an extremely flexible unit. This can really come in handy if you need to output the preamps to an EQ or compressor
before returning them for digital conversion.

It is worth noting that, in order to avoid ground loops, the DB25 ground connections are lifted on the Súper 8 side,
leaving the ground paths of your DB25 snakes only acting as shields and preventing any current returns.

TROUBLE SHOOTING
PROBLEMS
SOLUTIONS
There doesn´t appear to be any signal at all arriving at the
back XLR.
Make sure the GAIN knob is not in the ´Off´ position.
There still doesn´t appear to be any signal at all arriving at
the back XLR.
Check to see if a jack cable has been left plugged into the
front panel D.I.
Even at the lowest position on the GAIN knob I still have
too much gain.
When this happens you should activate the PAD button.
This will reduce the input by 20dB ahead of the input
transformer
Condenser microphones don´t seem to work with Súper 8.
Make sure the red +48 V button is pressed in to activate
the phantom power sent to the microphone.
There doesn´t seem to be any output at all from the unit.
Check to see if the OUTPUT knob is fully turned down as
this will attenuate the signal completely.
Sending a signal to the unit from a DAW overloads it
terrible.
It is necessary to press the LINE button when sending it a
line level source.
If not, it is expecting a Microphone signal with a very
different impedance.
There is no signal arriving from the ADC.
Make sure the corresponding button in the ADC Routing is
pressed if the Preamps direct out is desired.
There is still no signal arriving from the ADC.
Double check that the appropriate connector is indeed
inserted properly.
There are clicks being generated.
Make sure you have selected the correct Sampling
Frequency.
There are clicks being generated.
Make sure you are using a BNC cable to connect the
Word Clock if being slaved.
There are unexpected noises and/or jitter being produced.
If your unit is the last in a group of digitally synced units
you should press the ´75 Ohm Term´ button.
I have everything connected correctly but I’m still not
receiving any signal in my DAW.
Make sure you have selected the correct INPUT routing in
your DAW.
I have everything connected correctly to use the SPDIF
output but there is no signal arriving at the DAW.
Make sure you have correctly selected the button that
choose either SPDIF or AES/EBU.
