Fabricant: ATI
Disponibilité: Rupture de stock

The P100 interface is a high end Turntable Preamplifier and Pro level converter.  It provides standard RIAA Equalization and ouputs active Balanced +4 db levels for use in Pro recording environments and high end stereo systems.   If you need an RIAA preamplifier for transferring LPs  the  P100 provides excellent isolation with 2 level controls and Gold plated RCA jacks.  It also provides varying degrees of jumper selectable cartridge loading depending upon your application.

The ATI P100 Preamp has been out of production for some time, having been replaced by the P1000, which was also discontinued around 2005 or so.  The P100 is a bit hard to find.  This Encore Version of the P100 has white on black label, instead of the white on blue of the earlier version.  They both came in the same package and as far as we can tell, shared much of the same circuitry.   The

Never heard of ATI?  They've been building high quality, bulletproof gear for the Broadcast industry for more than 30 years.  bibbtek has been installing their products in places ranging from Edit suites and Audio Production Studios to Conference rooms and School Auditoriums, with a remarkably low failure rate.

We love this stuff.   This gear is very well constructed and designed by folks who know the business of delivering high quality audio dependably, in high RF environments without compromise.

We have ATI DAs that remain in continuous service since 1981!
