Need a cheap 2-channel receiver

Mazeroth

Looking for a solid state 2-channel receiver to do impedance measurements with when I design loudspeakers. If it doesn't have bass/treble controls then all the better!

Thanks!

Does it need to have a tuner?

Just out of curiosity... why do you need a receiver/amplifer to do (speaker) impedance measurements? I drive loudspeakers right off my signal generator when I DIY T/S parameter measurements.

That said, I am sure I have a spare -- or two -- gathering a layer of sediment in the basement. PM me if you wish and I can see what's on the slab.

Doro, the simpler the better. No tuner required.

What do you mean by off your signal generator? I'm using SoundEasy which requires the use of two "probes" with various resistor values that need voltage to measure properly. Everyone I know of uses a solid state amplifier/receiver to take their impedance measurements. The only other way I'm aware of is if you have a device like the Woofer Tester 3 which is USB powered and doesn't require a separate amplifier:

And yes, if you have some collecting dust by all means let me know what you have.

Thanks guys.

I use a tried and true Heathkit (analog) signal generator.

You do need a resistor to calibrate to read impedance directly (and accurately), but you don't need an amplifier if the signal generator can output 1V into the low impedance load.
