6.3 Line Out TRS
The ADI-2 FS has two unbalanced analog outputs that provide levels up to +19 dBu. The short
circuit protected, low impedance line outputs are available as 1/4" TRS jacks on the back of the
unit. Contact R (ring) is connected to ground by a 100 Ohm resistor, which also allows the use
of virtual balanced connections.
Both TRS outputs deliver the same signals and output levels as the XLR outputs.
6.4 Variable Output Level
The ADI-2 FS includes an option to control the output
level of the rear Line outputs via the VOL pot. In this
mode the current output level setting (+4/+13/+19)
stays active, optimizing the pot adjustment path and
enabling an offset between Phones and Line outputs.
This mode is activated and deactivated by pushing
the ANALOG OUPUT – LEVEL button for 2 seconds.
The LED of the currently active Output Level will light
up dimmed, and in full brightness again after
deactivation.
6.5 Phones
The PHONES output on the front offers the same outstanding technical specifications as the
rear outputs (e.g. 120 dBA SNR), thus can be used as high quality Line output as well. Chapter
13, Connector Pinouts, shows the required adapter cable 1 x TRS to 2 x TS, often referred to as
insert cable
.
The level of the headphone output is changed in a stepless way using the VOL pot. The special
High-Power² output design is not only of a very low impedance type (0.1 Ohms), but also offers
high headroom at up to +19 dBu (6.9 Vrms) maximum output level.
For low impedance headphones, the Phones output provides twice as much power as previous
High Power headphone outputs. For example, for 32 Ohms load 0.7 Watts are available per
channel. The ADI-2 FS uses the driver technology of the ADI-2 Pro, offering very low distortion
(THD) until it reaches clipping level.
