Line Out - RME Audio Micstasy User Manual

Instrument
The main difference between a line and an instrument input is its input impedance. The function
HI Z raises the input impedance from 5.6 kOhm to 470 kOhm.
The input Inst/Line operates fully servo-balanced even with Hi-Z activated.
The front inputs of the Micstasy offer an adjustable amplification from 0 dB up to +50 dB. This
equals a sensitivity of +21 dBu down to –29 dBu, referenced to full scale of the AD-converter.
Changing the gain is usually done click-free, as the gain change is performed during the zero
crossing of the audio signal, if possible.

13.3 Line Out

The Micstasy has 8 balanced XLR outputs on the back panel.
The electronic output stage does not operate servo balanced! When connecting unbal-
anced equipment, make sure pin 3 of the XLR output is not connected. A connection to
ground can cause a higher THD value (higher distortion)!
The button ANALOG OUT is used to define the analog reference level at the analog outputs.
The reference level is reached at full scale of the AD-converters, thus matching the front panel
level meter's level indication.

The Micstasy delivers an undistorted maximum level of +27 dBu. The referencing is based on
full scale of the AD-converters. 0 dBFS will be reached at +13, +19 or +24 dBu output level
respectively.
The different output levels guarantee optimal conversion results, while still being compatible to
any attached analog equipment. Note that ANALOG OUT has no influence on the technical
specifications – distortion, frequency response and signal to noise ratio do not change, or rather
exactly like the analog overall gain.
Set to +13 dBu and +19 dBu the Micstasy is fully compatible to all RME devices having +4 dBu
and Lo Gain as input reference.
