 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:
@@ Line 38: / Line 38: @@
 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
+===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
+===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.

 * The DA924 employs a linear power supply and generates a fair amount of heat in normal operation; so do not mount the unit in a manner that does not provide adequate ventilation. Ideally, no other equipment should be mounted one rack space above and below the unit. Factors such as the ambient temperature and range of temperature variation will affect how much space is needed to provide adequate ventilation.

 *The DA924 has a sophisticated self-calibration system that initializes every time the unit is powered. There are two stages of self-calibration; one which normally takes longer than the other. The first stage is initialization of the temperature-controlled “oven” which maintains the temperature of critical circuit elements. Once the “oven” temperature has stabilized, the second stage of calibration begins and ensures accurate conversion, even as components age. If the power is cycled after the DA924 has been in operation, the first stage is normally “skipped” or completes rapidly and only the second stage calibration ensues.
