Stanford Research Systems Perf-10 75ohm Master Clock

SRS Perf-10 Master Clock in excellent condition. I used this with my DCS DAC with excellent results. Simplified my system so this is no longer needed.

The Perfection-10 has eight 10MHz 75ohm outputs; compatible with all devices that accept a 10 MHz reference input.

This Perf-10 also has the12V DC power supply input which allows you to power it with your favorite LPS as well as direct to AC

From SRS:

Perfection is a high standard—but your studio clocks deserve nothing less. That's why we designed the PERF10 to offer audio professionals and demanding audiophiles a frequency reference of staggering accuracy and unmatched stability.

Up until now, atomic clocks marketed for audio use have been designed around commercial off-the-shelf rubidium clocks designed for the communications market—not audio. And while these rubidium clocks may have good long-term stability, they were never designed to provide low short-term jitter.

The PERF10 is built around Stanford Research Systems' own PRS10 rubidium oscillator. By designing and building the oscillators ourselves, we're able to craft an instrument perfectly matched to the demanding requirements of audio master clocks. Starting with an oven stabilized, 3rd overtone, varactor tuned, SC-cut crystal oscillator, the PERF10 offers both the accuracy and stability associated with rubidium clocks and unmatched jitter performance—30 dB better phase noise at 10 Hz off carrier than a competing "Swiss-made" rubidium clock.

And because we don't have to buy our oscillators from an outside source, we can offer you perfection. PERF10 has eight 10 MHz, 75 Ω outputs.
The core of the Perfection-10 is a proven ultra-stable rubidium oscillator designed and manufactured by Stanford Research Systems.
By designing and building the oscillator in-house, SRS are able to craft an instrument perfectly matched to the demanding requirements of audio master clocks..

When equipped with Option 01 PERF10 can be powered solely from an 12 VDC source, or the DC and AC power sources can be connected simultaneously with the DC supply providing an automatically switched redundant power source in the event of an AC failure.
