Putting Sound in the Picture

All audio processing is performed
within the Summa Core, no audio
is passed to the surface for
routing or processing. The only
audio connections on the Summa
surface are for the built-in talkback
microphone and the headphone
socket, both of which must be
connected to I/O box ports via the
surface back panel, to receive and
transmit audio.
These two figures show all Summa’s
surface audio connections. For details
on power connections see “Surface
Power Supply Unit” on page 33 and for
information on connecting the surface to
the processing core see “Connecting the
Surface to the Core” on page 12.
HEADPHONE AND TALKBACK MICROPHONE CONNECTIONS
Please note, the built-in Summa
headphone socket and talkback
microphone must be accounted for when
deciding on the number and placement
of Hydra2 I/O boxes during the ordering
process.

Connections
Summa’s built-in talkback microphone is
situated close to the Summa logo in the
Monitor panel, directly under the Touch
Display. The headphone socket is fixed
to the front right of the surface, just under
the arm rest.
The talkback microphone is connected
internally to an amplifier unit, and from
there to the male XLR plug on the rear
panel. In order to use the built-in talkback
microphone, this male XLR must be
connected to an I/O box input port.
The headphone socket is connected
internally to the output of a headphone
amplifier, the inputs of which are wired
directly to the two female XLR sockets
on the rear panel. In order to use the
headphone socket, these two XLR
sockets must be connected to two I/O
box output ports.
