Avid Pulsare II phono stage


Avid introduces the Pulsare II, building on the impressive successes of its predecessor now enhanced with switchable Mono and Subsonic Filters, conveniently operated from the front panel. Additionally, resistance values can now be customized. Internal RCA sockets allow different resistance plugs to be fitted to alter the 47k setting so perfect cartridge matching for those obscure loads becomes simple. This is done internally to maintain the shielding of the fully balanced circuit and prevent unwanted noise.

A fully balanced design, Pulsare II is built with purely exceptional high-specification components; with the singular goal of maintaining the purity and integrity of the miniscule signals flowing through it. To this effect, Pulsare's distortion across the audio spectrum is vanishingly low and Pulsare delivers impressive headroom; never running out of steam regardless of the demands of the music. A passive RIAA (with Neumann HF correction) circuit using audiophile-grade capacitors maintains linearity.

Front Panel Controls
Gain, Resistance and Capacitance are all easily adjustable via the front panel, offering excellent flexibility. All front panel selections are routed through high-quality, low-impedance relay banks allowing the use of much shorter electrical pathways and minimizing signal damage. Fully balanced, the Pulsare II offers both XLR and RCA inputs and outputs.

Outboard Power Supply
The massive external double regulated dual-mono 300VA power supply provides prodigious power to each channel separately. Separating Power Supply and Signal sections reduces noise, vibration and susceptibility to outside interference. This two-box configuration also allowed Avid to engineer a much larger, higher-current power supply which like the Reference PSU for the Avid Acutus, delivers greater drive, greater rhythmic capability and greater dynamic range.
