Introduction
9061 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 9061 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 the embedded or AES audio
outputs.
18 discrete sine wave frequencies are available, ranging from 50 Hz to 16 kHz
(default frequency is 1.0 kHz).
Audio Routing Example
Figure 1-8 shows an example of using the 9061 audio embedding/
de-embedding and routing functions to de-embed audio, 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 re-embed the
audio into the SDI video output. Additionally, the example shows how
external analog and internal tone generator sources can be embedded into the
SDI output (in this example, a provision for local station ID voice-over analog
and a tone).
Note that the source and destination correlations shown here are only
examples; any source can route to any destination.
