Stax headphone questions

amt · 26th May 2004, 07:22 PM

Hi,
I just picked up a pair of Stax sr-30 with a srd-4 adaptor and no manuel. My question is how does the adapter function. It has speaker terminals and a cable with raw wires (4) on the back. On the front is a switch that selects either "loudspeaker" or "earspeaker". Is the cable missing a headphone jack for plugging into an amp/receiver? And are the speaker terminals for connection directly to an amps speaker outputs? Are these still considered good headphones and worth the time/cost of repairing if need?

Thanks for any help on this.

If I'm not mistaken, your headphones are "electrets" meaning the charge is permanent. You don't need any additional power but you do need high voltage to drive them. The box is transformer and a headphpone jack will not do here. You must have an power amp to drive the transformer.

I have downloaded Stax manuals, not exactly this one, but I'm sure you can find it for your model.

The comfort (for my ears) aren't the best but the sound is
