27.2 Connector Pinouts
TS jack analog instrument input
The 1/4" TS jacks of the universal line/instrument inputs are wired according to international
standards:
Tip = + (hot), Ring = GND, Sleeve = GND.
XLR Connectors
The XLR sockets of the analog I/Os are wired according to international standards:
1 = GND (Shield), 2 = + (hot), 3 = - (cold).
The servo-balanced
input
circuitry allows to use monaural TS jacks (unbalanced) with no loss
in level. This is the same as when using a TRS-jack with ring connected to ground.
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 might cause higher THD (distortion) and power consumption!
TRS Phones jack
The output channels 3/4 feed the two
Phones
outputs via two independent
driver circuits, optimized for high (TRS
1/4”, 6.35mm) and low impedance
(TRS 1/8”, 3.5mm) headphones
In case this 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 channel
to the ring of the TRS jack/plug.
