13.
If the DAX-‐16 is using a BLU link interface, set the sample rate to match the rest of the BLU link
loop. This determines how many BLU link channels are available in the system. Note that the
Dolby CP850 runs 48kHz on the Atmos Connect loop.
14.
If the DAX-‐16 is being driven with one of the USL sound processors listed in the Load Default
Channel/Band Labels and Routing section, click the appropriate button to set these values.
15.
If the DAX-‐16 is not being driven by one of the listed USL sound processors, enter a channel
name, band name, and set the source for each output. If a crossover in the processor is not
being used, the Band Name can be left blank. Output numbers refer to the DE-‐15 connector on
the back, each of which carries two channels. For example, 8A and 8B are on the last two
outputs of the DAX-‐16. The channel name and band name can be in any language and use any
Unicode character supported by the browser.
16.
The default stream compressor settings (1ms attack, 256ms release) can usually be left as they
are. If desired, the attack time can be increased to reduce “pumping,” and the release time can
be decreased to increase the average volume.
17.
If desired, sent Bypass on digital input loss to Enabled. An analog bypass signal (fed to the DAX-‐
16 on the rear panel terminal block or through Digital Input B on the DAX-‐16C) is sent to the left
and right outputs on loss of the digital input signal or failure of the DAX-‐16.
18.
Adjust the output trims as required. When set to 0dB, the DAX-‐16 outputs 300mV RMS when
driven with a sine wave that peaks at -‐26dBFS. This level corresponds to the digital output level
of USL processors (26dB headroom). See the Browser Support section on how different
browsers handle the slider adjustments.
19.
Click the link to the Bar graph page. This page is shown in figure 7.
Figure 7 -‐ Bar graph calibration page.
20.
Apply a reference signal to each digital input. Press the Proc button to have the bar graphs
represent the DAX-‐16 outputs. Between each bar and each button are two rectangular areas.
Clicking the top area increases the bar graph display by 1dB. Clicking the lower area decreases
the bar by 1dB. Adjust each bar to 0dB with the reference signal driving the digital inputs.
21.
Press the Amp button to have the bar graphs represent the amplifier output sample (Vmon). As
in the previous step, adjust each bar graph to 0dB with the reference signa.
