I am now the proud owner of a Pulsar 23.

Looking at the Pulsar 23 User Manual, page 29 under SPECIFICATIONS, it clearly states:  “The range of input and output CV and audio signal 0 to +10 V”.

This indicates it has  DC coupling to the outside world.

My digital audio gear that I interface the Pulsar 23 to is A/C coupled, ok, so it has a series capacitor in there to filter out the D/C offset introduced by the Pulsar 23.

Are these statements exactly correct, the OUT 1/4 jack and the headphone output jacks on the Pulsar 23, what are they outputting, D/C coupled (0V to some maximum) or are they A/C coupled with a capacitor in series to filter out any D/C offset (-X volts to +X volts)?

The Pulsar 23 User Manual also states that the circuitry is protected against overloads and can receive signals in the range of -20 to +20 V, ok, so I am not going to damage my Pulsar 23 when I feed an A/C signal into it, but what happens to the negative part? Does the negative part get clamped to zero Volts or is the sign simply ignored?

I also own other Soma synthesisers (Pipe, Enner, Lyra 8 and COSMOS) in addition to my digital side which I know is A/C coupled.

How are these two worlds of A/C coupled and D/C coupled working together in the Pulsar 23, how does the Pulsar 23 handle this?

I halve already posted a question about apparently strange outcomes when I feed in an A/C signal into the CV pin of the Pulsar’s VCA, operating quit differently if that CV signal comes from the Pulsar 23’s LFO.

For me to best use my Pulsar 23, a bit of knowledge how these A/C and D/C interact in the Pulsar 23 will help me (and I suspect a lot of other users) a great deal.

PS. I do have a basic understanding of electronics, so you can hit me with the technical answers.

Looking forward to a response from the Soma Laboratory Team.

Kind regards,
