Edwards Audio C2 & P2 Pre-Power Amplifier
The C2 has a newly designed low noise power supply section based around a custom wound 100VA toroide ,the circuit topology is borrowed from the IA3 with the same FET input op-amps and an Alps Blue volume control. The input options are the same as the IA2 with 4 x LINE one of which is via a 3.5mm stereo jack for easy connection to portable devices, plus it has an MM input RIAA circuit for use with Turntables as standard. There is also an OPTO coupled mute link for connection to the P2 such that when the pre-amp is muted the power amp is as well.
The P2 is essentially the power amp section from the IA2 but without all the pre-amp supplies. It uses a Bi-Polar output stage with thermal compensation and is based around a custom wound 250VA toroide transformer and produces a healthy 65W into 8 Ohms. There is an 0V mute link connection which enables the P2 to be muted using the C2’s mute function. The P2 can be used with the C2 pre-amp to build a pre-power amp combination of exceptional sound quality for the cost, or it can be added to the IA2-R to create a bi-amped setup.
It makes an ideal partner with our SP2 floorstanding loudspeakers and TT2 turntable when plugged directly into the internal custom designed RIAA MM input board. This makes for a very well balanced and musical system who’s performance belies it’s modest price tag.
