does Cyrus amp need a load?

[tempus fugit]

Hey all;

My brother has a Cyrus amp that he would like to use a wireless headphone
set with. Trouble is, there's no headphone jack, so I was going to rig
something up where he could unplug the speakers and plug the wireless
transmitter into the speaker jacks. I'm pretty sure the amp is solid state.
Would there be any problem with this arrangement, or do you think the amp
needs a low impedance (8 ohms or less) load to run safely?

Thanks

No it doesn't.

Solid state amps do not need a load to operate safely. It's real simple to
tell if an amp is solid state: if it has no glowing vacuum tubes in it it's
solid state.

Make sure the wireles transmitter is designed to accept speaker-level
inputs. If it's expecting a line-level signal, less than 2V, you could
quickly fry it by using the speaker terminal outputs.

What is your goal here? Are you just wanting to use the input selector to
choose your source, then wirelessly transmit the source to a remote location
where it will be amplified? If so a better solution would be to use your
tape monitor outputs on the amp if it has them. You won't have tone or
volume controls, but the amp on the far end will anyways.

Thanks for the reply Dave.

The wireless transmitter has a 1/8" jack to connect to the source device, so
I'm assuming that the idea is you plug this thing into an iPod or whatever,
then you can wander around the house without having to drag your iPod around
(like it's too big to do that anyway). Anyway, he wants to use it for his
home stereo. My original idea was to use the line outs, but it seems to be
designed to be driven by a speaker out.

Very unlikely. It'll be a 3.5mm jack.
