Area 5.1
Sub/LFE channel
To separate those frequencies that are not localisable, a 24 dB
Butterworth low-pass filter can be activated at 130 Hz (Dolby
AC 3). If the low-pass filter is not activated, the output can be fed
to any other LFE processor to generate the Sub/LFE signal for
other encodings such as DTS.
Stereo downmix stages
The Area 5.1 allows to record 5.1 and stereo signals in parallel. For
each of the five channels a stereo downmix stage allows to control
the particular level and panorama in the stereo image. Each
channel is muted when the Mute switch is not pressed.
Dual concentric volume/pan controls
The inner ring of the dual concentric controls determines the
output level for the concerning channel. The control range covers
values from -65 dB to +12 dB.
The outer ring of the dual concentric controls allows to adjust
the panorama of the channel’s signal in the stereo image. The pan
control is center detended.
Gain control
To determine the output gain of the stereo downmix use the gain
control in the stereo output section. It covers values from
-80 dB up to +6 dB.Two peak LEDs illuminate 6 dB before clipping
for the left and right channel of the stereo signal.
Monitoring section
In the Monitor section a plug is installed on the front panel to
connect any stereo headphone.A volume control serves to adjust
the monitoring volume.
The L/R, SUB, SL/SR, C and Stereo buttons are used to select the
channels to be monitored. This way, any channel or channel
combination of the preamp output signal can be monitored.
Output PPM meter
The preamplifier output gain values for all 6 channels (L, C, R, SL,
SR, Sub) are displayed on the PPM output meters.The PPM meter
shows the peak levels and ranges from -48 dB up to +9 dB.
