Frequently Asked Questions - Súper 8 Heritage Audio

How do I troubleshoot no signal at the output?

Ensure the GAIN knob is not in the 'Off' position. Check if a jack cable is plugged into the front panel D.I. input (this disables the XLR input). Also verify the OUTPUT attenuator is not fully turned down.

Why is my condenser microphone not working?

Press the +48 V button to activate phantom power for that channel. This is required for condenser microphones.

What should I do if the gain is too high even at the lowest setting?

Activate the PAD button to reduce the input level by 20 dB ahead of the input transformer.

How do I connect a line-level source without distortion?

Press the LINE button on the corresponding channel. This switches the input impedance to accept line-level signals instead of microphone signals.

Why is there no signal from the ADC?

Check the ADC Routing buttons for the corresponding channel. If you want the preamp direct output, the button must be pressed. Also confirm the appropriate digital output cable is properly connected.

How do I eliminate clicks in the audio?

Ensure the Sampling Frequency selector matches your project settings. If slaving to an external word clock, verify the BNC cable is properly connected and the clock is stable.

What causes unexpected noise or jitter?

If the Súper 8 is the last device in a digital sync chain, press the 75 Ohm Term button to terminate the word clock signal. Incorrect termination can cause jitter.

My DAW is not receiving any signal despite correct connections. What's wrong?

Double-check your DAW's input routing. Ensure the correct digital input (ADAT, AES/EBU, or SPDIF) is selected and the sample rate matches.

How do I use the SPDIF output?

Connect the provided 9-pin breakout cable with RCA connector. Ensure the AES/EBU or SPDIF button is set to SPDIF mode. Also verify the sample rate and clock settings.

What are the special features of channels 1 and 2?

Channels 1 and 2 include a high-impedance JFET DI input on the front panel and a sweepable high-pass filter with continuously adjustable cutoff frequency, in addition to the fixed 82 Hz filter found on all channels.

USER MANUAL

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.

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 48 V, Line, Lo-cut(-3 dB at 82 Hz) 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 44.1 kH to 192 kH. 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.

All DB25 multi pin connectors are TASCAM protocol. This same protocol is also used by AVID amongst many others, and is a follows:

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.

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 u 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.
