Product Description

The LavryGold DA924 is a high-end stereo DA converter intended primarily for Mixing and Mastering applications; with balanced professional level XLR outputs as well as unbalanced consumer level RCA (IEC) outputs. The output level is adjustable using rear panel trimmers. There are two AES/XLR and one SPDIF RCA (IEC) input that accept stereo digital audio inputs.

Analog outputs

The DA924 has electronically balanced XLR outputs which can be configured for unbalanced operation using internal jumpers. The unbalanced RCA (IEC) outputs output a lower level signal more suitable to consumer level equipment. The rear panel trimmers adjust both XLR and RCA output level with the following range with a peak digital input level of 0dBFS:

The XLR output is Pin 2 "+" and Pin 3 "-" for normal signal polarity when the front panel Polarity setting (“INVERT” switch and LED indicator) is “Off.” Thus, for the DA924 with balanced or unbalanced XLR Pin 2 "+" connections, the signal polarity is "normal" or "non-inverted." Changing the front panel Polarity setting to “INVERT” (LED indicator illuminated) will result in inverted signal polarity for balanced and unbalanced Pin 2 "+" connections, as well as RCA (IEC) connections.

Digital input

There are (3) stereo digital audio inputs on the rear panel of the DA924- (2) XLR/AES inputs which can accept either AES/EBU or SPDIF/IEC inputs. SPDIF/IEC sources can be connected using simple wired adapters or adapter cables (no transformer is required or recommended for cable lengths that conform to recommendations for coaxial 75 Ohm consumer digital audio cables). The IEC input can accept SPDIF (IEC 60958 type II) stereo digital audio inputs.

Synchronization

The DA924 always locks to the incoming digital audio signal and provides excellent immunity from jitter in the incoming signal degrading the DA conversion. For input signal with a sample frequency of 44.1 or 48 kHz, the Lavry exclusive CrystalLock™ mode provides the ultimate in jitter immunity from consumer sources such as a CD player. For digital audio inputs with 88.2 or 96kHz SF, an advanced three-stage PLL provides excellent jitter immunity.

AC Power

The power selector of the DA924 must be set to the proper AC power voltage before AC power is applied.

See LavryGold voltage setting for details on the AC power voltage setting and accessing the fuses.
