2.2 Back Panel Connections
Mic / Line Inputs (Studio 1824 only). The combo
connections on the rear panel of the Studio 1824 can
be used for both microphones and line-level devices.
Use the XLR connections for microphones and D.I.
boxes and the 1/4-inch TRS inputs for line-level
signals up to +18 dBFS. The trim control on the front
panel provides gain for both input types.
Line Inputs (Studio 1810 only). Use these ¼-inch TRS inputs with line-level devices.
These inputs are scaled to accept line-level signals up to +18 dBFS.
Power User Tip: These inputs are direct-to-ADC. As such, no gain control available.
Typical examples of line-level connections are synthesizer outputs, signal processors, and
stand-alone mic preamps and channel strips. Use the output level control on your line
level device to adjust its level.
Line Outputs. These balanced ¼-inch TRS line outputs can be
used to route audio to external devices, such as headphone amps,
signal processors, and additional monitors. Studio 1824: The first
two outputs share their playback streams with both the main
outputs and Headphone 1. Outputs 3 and 4 share their playback
streams with Headphone 2 for both the Studio 1824 and the
Studio 1810. All other outputs have their own independent playback streams.
Power User Tip: Every line output is DC coupled to provide control voltage to external
analog equipment. This feature can be used with any plug-in that supports it.
Main Outputs. These are the main outputs for your Studio-series interface. The
output level of the Main Outputs is controlled by the Main Level control on the front
of the unit. Playback streams 1 and 2 are routed to the Main Outputs in addition to
Outputs 1 and 2 (Studio 1824 only) and Headphone 1.
S/PDIF Input and Output. The S/PDIF connections allow two channels of audio to
be transmitted and received at rates up to 24 bit, 96 kHz. The S/PDIF I/O also allows
your Studio-series interface to send and receive word clock to external digital
devices.
Power User Tip: In UC Surface, you will need to set “S/PDIF” as the Clock Source and the
sample rate to correspond to the external device when using an external S/PDIF device as
your master clock. See Section 4.1 for details.
ADAT – S/MUX Input (Studio 1810 and Studio 1824) and Output (Studio 1824
only). These are the ADAT – Dual S/MUX connections for your external digital devices.
When recording or playing back at 44.1 or 48 kHz, each ADAT I/O will provide eight of
the sixteen available channels consecutively from left to right. When recording or
playing back at 88.2 or 96 kHz, each connection will provide four of the available eight
channels. These inputs and outputs do not function at 176.4 or 192 kHz:
ADAT Input (Studio 1810 and 1824) ADAT Output (Studio 1824 only)
44.1 / 48 kHz Channels 11-18 Channels 11-18
88.2 / 96 kHz Channels 11-14 Channels 11-14
