Channel Islands PEQ-1 MKII MM/MC Phono Preamp

1 Review

Clean & Isolated Power

The internal design of PEQ-1 starts with a dual AC input (one for each channel). When the outboard power supply is connected, the AC is fed to two independent filter/regulation circuits (1 per channel). These circuits feed the L & R audio stages with ultra-low noise on par with the best battery technologies, and without the inconvenience. There is also a Chassis Ground switch to optimize chassis shielding. The standard AC supply is an AC wall adapter type with a single winding feeding the L&R circuits. This supply is 120V input only.

Top-Notch Audio Circuitry

Input signals are connected via highest quality Cardas™ panel-mounted RCA jacks. The input jacks are routed to two independent mono circuits of identical layout. This assures exact performance from both channels and reduces crosstalk. Circuit topology consists of an input gain stage with selectable resistive load, capacitance, gain, and subsonic filter. This gain stage is followed by a passive high frequency cut, then an active bass boost to create the RIAA equalization curve, then to the output jacks. Careful layout yields a very short signal path from input to output, and a combination of star grounding power supply components/ground plane for the audio circuits, result in a silent background and immunity to EMI/RFI pickup. The entire circuit board is then housed in a heavy steel faraday cage to further reject outside interference, then inside the attractive aluminum outer chassis.

    A superb phono stage for any Audiophile!


    I recently purchased this phono amp as a upgrade for my system. I immediately noticed a difference from my previous phono stage. Vocal performances seemed to be a lot more realistic while maintaining the warm sound I enjoy. I also noticed that my noise level was considerably reduced. The build quality of the PEK-1 blows away most all other phono amps in it's class easily. Customer service with the manufacturing company and Needle Doctor was awesome, they answered all my questions before purchasing. A sure fire great buy!
