Front Panel Connections and Controls

Input Meters. These LED meters show the input level of the analog inputs on your
Studio-series interface. The red Clip LED will illuminate when your input signal
reaches -0.5 dBFS. At this level, the signal will begin to overload the analog-to-digital
converters and exhibit signs of clipping. Use the gain controls to keep the signal
below this level.
Output Meters. These meters display the signal level received from the first two
driver returns (Main Left/Right). These meters have the same range as the input
meters (-50 dBFS to -0.5 dBFS) and are after the main output level control.
Mute. Press the Mute button to Mute the Main Output signal. The button will
illuminate Red when Mute is active.
Sync LED. This light indicates if your Studio-series interface is in sync with your
computer. When no sync is available, this light will flash red/blue. For Studio 1810c,
this light will also indicate if your external S/PDIF sync source is available. This light
will also flash if the sample rate you have set on your Studio-series device does not
match the sample rate you have set on your external clock source device.
Mono (Studio 1824c only). Press this button to sum the Main stereo output signal
to mono.
Power User Tip: Studio 1824c users can utilize the Mono feature to verify mono
compatibility and to check for phase cancellation in your stereo mixes.
Cue A/B (Studio 1810c only). This button allows you to switch the source that you
listen to through the Headphone 1 output. When the button is not illuminated,
playback streams 1 and 2 will be routed to the headphone output. Press the button
to route playback streams 3 and 4 to the Headphone 1 output instead.
Headphone Level. Your Studio-series interface provides two high-power
headphone outputs, each with its own level control. Studio 1824c users will find
both the headphone outputs and level controls on the front panel. Studio 1810c
users will find the level controls on the front panel and the outputs themselves on
the rear. On both units, Headphone 1 shares a stereo playback stream with the main
outputs and Headphone 2 shares its streams with outputs 3 and 4. For Studio 1810c
users, Headphone 1 can be switched between the two sets of streams via the A/B
button.
Main. The main knob controls the output level for the main left/right outputs on the
back of your Studio-series interface and has a range of -80 dB to 0 dB. This control
provides attenuation only.
Power Button and Sync light (Studio 1824c only). The lighted ring around the
power button of your Studio 1824c is a clock source indicator. It lets you know if your
unit is receiving word clock correctly.
• Blue. When this light is blue, your Studio 1824c is either the
master clock of your system or is receiving word clock from a
designate external source via the ADAT or S/PDIF input.
• Flashing Red and Blue. When this light flashes between blue
and red, your Studio 1824c is detecting a clock source.
•
Purple. If this light is purple, your Studio 1824c cannot detect a clock source.
Power User Tip: Word clock is the timing signal with which digital devices sync frame
rates. Proper word clock sync prevents digital devices from having pops, clicks, and
distortion in the audio signal due to mismatched digital audio transmission. In general,
you will use your Studio 1824c as the master clock in your studio, and it provides high-
quality word clock for this purpose. However, in the event you would like to use another
device as the master clock, you can set the input source for clocking in UC Surface (see
Section 4.1 for details).
