Cobalt Digital COMPASS 9301 AES Audio Delay - Manual (Page 15)

9301-OM (V4.2) 9301 PRODUCT MANUAL 1-11
Introduction
9301 Functional Description
Loudness Processor (Option +LP)
Note: Loudness processor function is an optional licensable feature. This function
and its controls appear only when a license key is entered and activated.
(This option (identified in Cobalt
® price lists as +LP) can be purchased upon
initial order, or field-activated using a key string which is sent to you when this
option is purchased.)
If your card was purchased with option +LP , loudness processor manual
supplement “5.1 and Stereo Loudness Processing Options for Compass ®
Cards (+LP51, +LP20) Manual Supplement” (OPT-SW-LP-MS) is included
in your documentation package. Supplement OPT-SW-LP-MS can be
downloaded from our website or requested using the Cobalt contact
information in this manual.
Tone Generator Function
The 9301 contains four built-in tone generators (Tone Generator 1 thru Tone
Generator 4). Each of the four tone generators can be set to a different
frequency, and are available as audio sources for each AES audio output.
18 discrete sine wave frequencies are available, ranging from 50 Hz to 16 kHz
(default frequency is 1.0 kHz).
Audio Routing Example
Figure 1-5 shows an example of using the 9301 audio routing functions to
route the audio to discrete outputs for post-production processing (in this
example, a console used for post-production EQ, levels, and monitor), and
finally redirect AES audio to selected output channels. In the example, delay
can be applied to the
AES 4 path to match any delay experienced over the
AES 1 thru AES 3 paths. An internal tone generator is also applied to an
available AES output channel (AES Ch 6). In this example, unused channel
outputs (AES Channels 9, 10, and 16) are set to Silence.
Note that the source and destination correlations shown here are only
examples; any source can route to any destination.
