Surround Monitoring 161
DM2000 Version 2—Owner’s Manual
When the MONITOR L/R to C-R button is on, the Left and Right Surround Monitor Chan-
nels are fed to the Control Room Monitors. This is useful when you want to use the same
speakers for Left and Right Surround Monitors and Control Room Monitors.
STATUS: SURROUND MODE indicates the currently selected Surround mode, which is
set on the Surround Mode page (see page 97). MONITOR LEVEL indicates the volume set-
ting of the SURROUND MONITOR LEVEL control, which can be calibrated to 85 dB SPL,
the cinema standard for setting up Surround Channel Monitor speakers. To do this, output
pink noise from the built-in Oscillator (see page 161), set the SURROUND MONITOR
LEVEL control and the level controls on the Surround Monitor speaker amps so that the
total output is 85 dB SPL, then press the SET SPL85 button. The MONITOR LEVEL indi-
cation will then display the volume setting relative to 85 dB SPL. Press the SET SPL85 but-
ton again to return to the normal volume indication. Press the SNAP TO SPL85 button to
reset the SURROUND MONITOR LEVEL control to 85 dB SPL.
Configuring Surround Monitoring
Surround monitoring, including speaker setup, monitor matrix, Bass Management, and
monitor alignment, is configured on the Surround Monitor Setup page.
1Use the MONITOR [DISPLAY] button to locate the Surround Monitor Setup
page.
2Use the cursor buttons to select the parameters, and use the Parameter
wheel, INC/DEC buttons, and [ENTER] button to set them.
SPEAKER SETUP: These parameters are for setting the volume balance of the surround
monitor speakers. Select the OSC (Oscillator) parameter and choose from PINK NOISE,
500-2K (pink noise through a 500 Hz to 2 kHz BPF), 1K (1 kHz sinewave), or 50 Hz (50 Hz
sinewave). Use the ON/OFF button to turn the Oscillator on and off. When on, the Oscil-
lator outputs a signal at –20 dB to the Surround Channels whose icons are highlighted. You
can turn on and off Oscillator output for speakers individually. Speaker icons can be
selected by using the cursor buttons. The signal phase of the LFE Channel can be reversed
by using the SW phase button. When ROTATE is on, the Oscillator signal is output by each
speaker in turn in a clockwise direction (3 second signal, 2 second pause).
SURR. MODE: This indicates the currently selected Surround mode, which is set on the
Surround Mode page (see page 97).
MONITOR MATRIX: This is used to select the Surround Monitor Matrix. In 6.1 Sur-
round mode, you can select 6.1, 5.1, 3-1, or ST. In 5.1 Surround mode, you can select 5.1,
3-1, or ST. In 3-1 Surround mode, you can select 3-1 or ST.
When a down mix Monitor Matrix is selected, you can attenuate signals by using the ATT
parameters.
You can use the Surround Monitor settings in Stereo mode, but Monitor Matrix is fixed to
ST.
