The highly-advanced ProLogue Premium Series is now available and man, is it sweet… blending the cutting-edge technology of the original ProLogue and DiaLogue Series with brand-new advances. First, the amps… stereo, mono and integrated. The ProLogue Premium Series unveils new, innovative circuits that provide unparalleled reliability, protection and sound quality:
- Bad Tube Indicator: A small LED for each power tube that lights up if it goes bad. Replace it and rock on.
- PTP-circuit: Cuts the juice if the power transformer overheats then resets after cooling down.
- OTP-circuit: Disables the output transformer in the event of massive tube failure or user error.
Now factor in these features upgraded from the critically acclaimed ProLogue and DiaLogue Series:
New Adaptive Autobias circuitry. Just flip a switch to optimize the amp for KT-88 or EL-34 power tubes. And the amp can be ordered with either.
New output and power transformers. Updated from DiaLogue and providing even better control over challenging speaker loads.
New front-end circuitry. Optimized for 12AU7s which helps produce lower distortion.
Home theater pass-thru implementing direct-line circuitry and gorgeous, full-function remote which controls CD player functions as well.
Next, let’s take a look at a real giant-killer… the ProLogue Premium Preamp!
Take the new front-end design, the PTP-circuit, the home theater pass-thru, the full function remote and then add new power transformers. They’re heavy-duty, dual-mono, with additional windings added to each for improved synergy with the optional MM Phonostage.
This pre-amp weighs in at a hefty 37.5 pounds… that’s some serious iron!
Finally, take a look at the parts ProLogue Premium counts as standard: ceramic tube sockets; Solen, Swellong, and Nichicon capacitors; WBT-style solid core speaker terminals; ALPS Blue Velvet volume control; gold-plated RCA jacks; and toroidal power transformer.
The entire ProLogue Premium Series is built by hand with the finest point-to-point wiring and quality equal to – or better than – any product you can buy at any price.
It represents the next step in PrimaLuna’s ongoing advance with high fidelity components.
