-The Quintessence adjusts automatically to AC power inputs of 90-264 [[VAC]] @ 47-63[[Hz]]. There are no settings to change. The AC power input module contains line filtering and two 1.25A 250V time delay fuses in a red fuse holder/voltage selector. The power supply will operate properly over the entire rated input range with the voltage setting of the power input module’s red fuse holder/voltage selector inserted in either the 115 or 230 position.

 ==Product Description==
-The LavryGold Quintessence is a high-end stereo DA converter with monitor control functions. It features one stereo DAC with two stereo XLR outputs designated MAIN and MONITOR. The MAIN output is fixed-level and the MONITOR output level is controlled by the front panel Volume control. Volume control is accomplished in the analog domain by proprietary digitally controlled analog circuitry.

Volume control is accomplished in the analog domain by proprietary digitally controlled analog circuitry.
 There is a unique Volume setting for each of the three digital inputs (2 [[XLR]] and one [[RCA]]). The Volume settings are stored in memory, and recalled when the input is selected. This allows the listening level to be equalized for digital sources with different levels. The Volume can be adjusted over an 80 [[dB]] range in one-quarter dB steps. The ¼ dB adjustment is retained when switching between 1/4dB and 3db adjustment modes so a precise monitoring level can easily be reset, even when the Volume is adjusted in 3dB steps.

 The MAIN output would typically be used as a source for analog processing in Mastering or “insert” processing of a track in multi-track applications. If an external monitor controller is available, the MAIN output can be connected to a monitor input. Connection of the MAIN output to a monitor controller ''will not'' allow the level compensation capability of the MONITOR output to be utilized when comparing digital sources using the front panel input selection.
-The MONITOR output would typically be used to feed a monitor input on an external monitor controller, or can be used to feed powered monitors or a power amplifier directly with the front panel Volume and Output Enable controlling the listening level.

 If precise level adjustment of the output is required when using the Quintessence as a source for analog processing, the MONITOR output can be used, and the level set using the front panel Volume control. The proprietary Volume control circuit offers less signal degradation than a conventional rotary potentiometer, resulting in signal quality being retained over a wide range of output levels.
