BHK Pre - Headphone Amp Specs?

I could not find any specs of the headphone amp of the BHK Pre, especially about the connector/jack. What size is it? Is it balanced? There is an outdated post with a link that does not work anymore… Maybe a good reason to update the product manual?

It’s a 1/4 inch jack (standard full size).

balanced?

I don’t understand. It functions as a normal headphone jack …

There are mono jacks, two channel jacks and presumably jacks with more sleeves to cater for balanced operation (like those 4.4mm headphone jacks) - they all have a tip and a number of sleeves.

Update - I think I boobed, the notation is TRS, tip, ring, sleeve, so it’s the number of rings that determines the channels (if channel is the correct term!)

It’s a two channel (stereo) headphone jack, nothing unusual or esoteric.

Is it too much to ask PS-Audio to specify the headphone jack in the datasheet or product manual?

What specification do you need?

How about some specification? I could not find any in the manual.

Again, what specification do you need?
