28. Analog Outputs

28.1 Line

The eight short circuit protected, low impedance line outputs are available as 1/4" TRS jacks on the back of the unit. The electronic output stage is built in a servo balanced design which han- dles unbalanced (mono jacks) and balanced (stereo jacks) correctly.

To maintain an optimum level for devices connected to the analog outputs, the Fireface 800 internally uses hi-quality electronic switches, which allow for a perfect adaptation of all outputs to the three most often used studio levels.

As with the analog inputs, the analog output levels are defined to maintain a problem-free op- eration with most other devices. The headroom of the Fireface 800 lies between 9 and 15 dB, according to the chosen reference level:

Reference

0 dBFS @

Headroom

Hi Gain

+19 dBu

15 dB

+4 dBu

+13 dBu

9 dB

-10 dBV

+2 dBV

12 dB

With +4 dBu selected, the according headroom meets the latest EBU recommendations for Broadcast usage. At -10 dBV a headroom of 12 dB is common practice, each mixing desk op- erating at -10 dBV is able to send and receive much higher levels. Lo Gain is best suited for professional users who prefer to work balanced and at highest levels. Lo Gain provides 15 dB headroom at +4 dBu nominal level.

The above levels are also found in our ADI-8 series of AD/DA converters, the Multiface, and even in our Mic-Preamps QuadMic and OctaMic. Therefore all RME devices are fully compati- ble to each other.

28.2 Headphones

Channels 9/10 of the Fireface are available on the front via one 1/4" unbalanced TRS jack (ste- reo output). These channels use the same converters as the other Line outputs, therefore offer the same technical data (119 dBA SNR!).

Instead of using internal electronic switches, their output level is changed step-less with the VOL pot. These outputs are special low impedance types, ready to be used with headphones. But they can also be used as high-quality (yet unbalanced) Line outputs.

Like all other outputs, channels 9/10 can also be controlled by TotalMix regarding level and monitoring of any input or playback channels (submix, like factory presets 1 and 2).

In case the output should operate as line output, an adapter TRS plug to RCA phono plugs, or TRS plug to TS plugs is required.

The pin assignment follows interna- tional standards. The left channel is connected to the tip, the right chan- nel to the ring of the TRS jack/plug.
