Vintage Analogue meets Modern DSP

Featured: Dirac Live Digital Room Correction,
JBL 4344Mk2 speakers,
Berning Siegfried amplification

BAS member Ken Schwarz will demonstrate what can be achieved by combining vintage high-end audio gear with modern digital correction. Large-format, horn-driven speakers of the 1970s-1990s produce an effortless and full-range sound, but can be difficult to position and adjust for low coloration. Ken’s using an inexpensive MiniDSP-based Dirac Live processor to judiciously clean up residual amplitude and phase errors as well as to provide a line-level crossover into bi-amped JBL 4344Mk2 speakers. Bass is driven by a Crown PS-400 solid-state amp, and mid/HF/UHF is driven by a Berning Siegfried amp, an unusual 10W, single-ended triode, output transformerless (OTL) design.

Attendees are encouraged to bring CDs, SACDs, LPs, or Mp3s of music they'd like to hear in the system.

Refreshments will be provided at 6PM
