Analog Outputs - RME Audio M-16 DA User Manual

10. Analog Outputs

The M-32 DA's rear has 32 balanced Line outputs, provided
by 1/4" TRS and four 25-pin D-sub connectors. They have
their own output drivers respectively and can therefore be
used simultaneously.
The electronic output stage of the TRS jacks is built in a
servo-balanced design which handles unbalanced (mono
plugs) and balanced (stereo plugs) correctly, automatically
adjusting the level reference. The maximum output level is
+21 dBu.
When selecting +24 dBu the LEDs +19 dBu and +24 dBu
are lit at the same time, because the TRS jacks stay at the
+19 setting, while the D-sub connector outputs are oper-
ated in the +24 setting.
The electronic output stage of the D-sub connector does not operate servo-balanced!
When connecting unbalanced equipment, make sure pin 3 of the XLR output is not con-
nected. A connection to ground can cause a higher THD value (higher distortion)!
The 25-pin D-sub connector follows the pinout known from devices manufactured by Tascam
(pinout see chapter 15.9). Your local dealer will supply analog breakout multicores D-sub to
XLR in Tascam pinout in different lengths.
Each output channel has its own 6-segment level meter, so every channel can be checked for
output signal and overloads easily. The level data are taken directly in front of the DA-converter.
The red LED OVR lights up 0.2 dB before full scale level (-0.2 dBFS).
One of the main issues when working with an DA-converter is to maintain the full dynamic
range within the best operating level. Therefore the M-32 DA internally uses hi-quality electronic
switches, which introduce no additional noise or distortion to the audio path. The key ANALOG
OUTPUT allows for a perfect adaptation of all 32 channels to the most often used studio levels.
The different output levels guarantee optimal conversion results, while still being compatible to
any attached analog equipment.
The M-32 DA uses the following level references:

Set to +24 dBu the M-32 DA is compatible to SMPTE (+24 dBu @ 0 dBFS, +4 dBu with 20 dB
of headroom).
