Pyramid SEA2500 Pre Amp

Really hard to get a decent, but well priced Preamp of this type. Essentially using this a s a line mixer for a drama/dance studio. Highly recommend this mixer. Well priced and pretty solid.

Does what it says it will do - seems to be a fine device

September 10, 2013

I replaced an integrated amplifier with this device and a dedicated amp. This has easy to read controls and does not produce heat. It has no noticeable background noise, not even with headphones.
