We offer the CONTROL MASTER PREAMPLIFIER in two versions: LINE only or with PHONO (MM & MC). The design is completely DUAL-MONO with separate power supplies for each channel including two custom designed power transformers. The audio boards are also separate. All the wiring from the rear input connectors to the front selector switch and precision custom stepped attenuator is painstakingly hand wired using professional studio twisted pair shielded six-9's copper cable for optimum shielding and low noise characteristics, and although it would be much cheaper, easier, and faster to simply put these leads on several feet of printed circuit board traces like most everybody else does, we opt for purity of sound however many more hours it takes. The high-current line amplifier circuit employed here is one we have developed and refined over the years in our MANLEY Professional series. We hope you agree with us and hundreds of satisfied users and studios around the world that this circuit really delivers.
