Control Room Output Controls

Output On/Off Switches

The Control Room monitor system has three outputs:

• Main Control Room Outputs (8 channels)

• Alt Control Room Outputs (8 channels)

• Mini Control Room Outputs (2 channels)

Only one output can be active at a time. The Output On/Off

switches follow exclusive-or (non-latching) behavior. When

you activate an output, its name and gain value (in dB) are

shown in the monitor section display.

Output Level Controls

Each of the three Control Room Outputs has a touch-sensitive

rotary encoder for control of output level. When any of these

encoder knobs is touched, the monitor section display shows

the output name and its current level in dB. Gain ranges from

a minimum level of –INF to a maximum level of +10 dB, in

1dB steps.

Output Level Trim Mode

Each output level control can be trimmed independently, to

allow for setting of different reference levels or to compensate

for differences in gain structure. Available trim values range

from –20 dB to +10 dB, in 0.5 dB steps.

To trim output levels:

1 Press and hold the On/Off switch for the output you want to

trim, until the switch flashes.

2 Turn the corresponding encoder knob to set the trim value.

The monitor display shows “Trim” and the trim value in dB.

3 Press the flashing On/Off switch to exit Trim mode.

Dim Level Control

The Dim Level control lets you adjust the amount of level re-

duction applied by the Dim switch, located at the bottom of

the Monitor section. Level reduction ranges from –30 dB to

0dB, in 1dB steps.

When the Dim encoder knob is touched, the monitor section

display shows “Dim” and the gain reduction in dB.

Monitor Output Mode Controls

Setup Switch

This function is currently not implemented for D-Control.

Calibration Mode Switch

The Calibration Mode switch invokes a mode that changes the

output value displayed by the Monitor section display from

gain (expressed in dB) to sound pressure level (expressed in

dB SPL) for each of the control room outputs. This switch

lights when an SPL value is shown for the active output.

To display output levels in dB SPL, you must first calibrate

each output. This SPL calibration requires the use of a pink

noise source (or other reference material) and a sound pressure

level meter to measure the output of individual control room

speakers.

To calibrate Control Room outputs to display SPL:

1 Send the reference material to the Main Control Room Out-

puts, and set the output level in Pro Tools to your studio ref-

erence level (for example, –18 dBFS).

2 Pan the signal to center (so that equal level is sent to all

Main Control Room Output speakers).

3 Set the speaker-to-speaker balance for all speakers in the sys-

tem using Output Trim mode for each channel, using the

sound pressure level meter to measure SPL at the mix position.

See “Individual Output Trim Mode” on page 111.

4 Solo the Center speaker, and adjust the Main Control Room

Output level encoder until the sound pressure level meter

measures the target reference level (for example, 85 dB) at the

mix position. You can Output Level Trim mode for fine ad-

justment of the output level. See “Output Level Trim Mode”

on page 109.
