RB-DS2 Stereo Audio Delay Synchroniser

System

Number of Audio Processors
One stereo or two independent mono audio processors

each consisting of the following cascaded processing elements: Internal Processing: Input —>Stereo Enhancer —>Two-Band defeatable AGC with window gating —>Five-Band Equalizer/HF Enhancer —>Multiband Compressor —>Look-ahead Limiter —> Automatic Loudness Controller —>Output.

Number of Channels:
The 1101 audio driver allows it to appear as two standard sound devices to the computer operating system. Each of the two sound devices can handle one stereo channel or two mono channels. The channels can be mixed and routed via a three-bus mixer ("Processed

" "Direct 1

" and "Direct 2")

however 1101 can only apply stereo or dual-mono audio processing to the output of the "Processed" bus. The remaining two "Direct" busses are applied to the Output Routing Switcher but cannot be further processed. See block diagram.

Frequency Response:
±0.1dB

2-20

000Hz

Input/Output Delay:
Adjustable from 25 ms to 62 ms in 1 ms steps. Presets available for one frame of: 30 fps (33.33ms)

29.97 fps (NTSC color video; 33.37ms)

25 fps (most PAL video; 40ms)

and 24 fps (film; 41.67ms). "Minimum" delay is also available; this delay will vary according to the processing structure in use and crossover mode settings.

Internal Filters:

15

and 20kHz can be used to provide additional anti-aliasing for low sample rate services

such as Internet Streaming Encoders

Eureka-147 (24kHz mode)

iBiquity HD-AM (32kHz) and Digital Radio Mondiale.

Internal Sample Rate:
48kHz.

Wave Sample Rate:
8-96kHz.

Internal Resolution:
24-bit fixed point (3 x Freescale DSP56367).

Input/Output Resolution:
24-bit.

Peak Control Accuracy:
If output samples are synchronous with internal samples

maximum overshoot of any output sample is 0.1dB. This is true at 48kHz output sample rate. If sample rate conversion after internal processing makes output samples asynchronous with internal samples

output samples can overshoot as much as 1dB (0.3dB typical).

Phase Response:
All processing is linear-phase (constant group delay).

AGC (Automatic Gain Control):
±12dB/24dB gain range

Two-Band

Gate and Window enabled.

Stereo Enhancer:
Two styles available: (1) Orban-patented L-R dynamic expansion triggered by L+R transients; (2) L-R delay.

Equalizers:
Shelving Low Bass EQ

selectable 6 dB

12dB or 18dB/octave. Three-band Parametric EQ with analog-style bell-shaped curves. Program Adaptive HF Enhancer.

Multiband Compressors:
-24dB gain range

Five-Band and Two-Band

selectable by mute-free crossfade.

Limiter:
-12dB gain range

Look-ahead IM distortion reduced

competitive with the best dedicated mastering limiters

achieving high loudness with a remarkable lack of side-effects.

Loudness Controller:
Constrains subjective loudness to a user-adjustable threshold via the 1981 Jones & Torick CBS Technology Center algorithm

as further refined and developed by Orban. The algorithm also drives a subjective loudness meter

which is displayed on the 1101's GUI. In dual-mono mode

there are two independent loudness controllers and meters.

Number of Factory Presets:
More than 20

each with 19-step LESS-MORE control. Presets are fully customizable with FULL CONTROL. In addition to presets for full processing

there are also "AGC" and "Look-ahead Limiter" presets.

Number of User Presets:
Essentially unlimited. User presets can be saved on the host hard drive or on other storage devices.

WAVE AUDIO INPUT

Number of Inputs:
2

Configuration:
Stereo

Sound Devices:
2

Driver:
Multiclient Driver allows 1101 to appear as two standard sound devices to the computer operating system. The input can therefore be received from multiple software applications running on the host computer system by use of standard operating system sound device driver calls. For example

this could include single or multiple player applications

such as an audio playout system with multiple players

content insertion system

or audio over IP routed into the host computer through an Ethernet port

and/or multiple streaming audio encoders. Because the driver is multiclient

it allows it to source multiple applications simultaneously. A versatile mixer and router application allows you to mix digital

analog

and wave inputs to three busses (one with OPTIMOD-PC processing and two without) and to route the outputs of the "Processed" and "Direct" busses to the Analog

Digital

and Wave Outputs in any configuration or combination

such that any output can receive any bus or the unprocessed Wave Input. Content insertion systems that would normally require two sound devices can be configured to work with one 1101 Optimod-PC

requiring only one PCI or PCIe slot per program source.

Sample Rate:
8-96kHz. Asynchronously Sample Rate Converted by Driver

Sync:
Internal free running or External. Either AES/EBU

Word Clock

or 10MHz input can be used as source for external sync.
Wave data will be clocked to software configurable Internal or External sources.

Input Level:
Variable within the range of -20 to 0dBFS (Peak) in 0.5dB steps.

Software adjustable via Optimod-PC Mixer Application and Windows Mixer API

eliminating any unnecessary digital sample rate conversion. Content insertion systems that would normally require two sound devices can be configured to work with one 1101 Optimod-PC

Software:
Mixer application provides complete control of digital mixer and all hardware settings.

The control application provides subjective adjustment controls of the audio processing and remote administration. It also allows factory and user presets to be recalled from and save to a host storage device such as a hard disk drive or removable drive. The control application client addresses multiple Optimod-PC cards

either housed in the local host or anywhere on a TCP/IP network or by local serial communication. The control application also functions as a server

interfacing cards installed in a given host computer with the network for control and monitoring.

API:
Microsoft Windows Mixer Control API supported for Input and Output switching and levels. This provides compatibility with Windows applications that use standard Microsoft Windows Mixer enumeration and calls.

IP API provides complete remote administration over TCP/IP. The OPTIMOD-PC Service application hosts a TCP/IP Terminal Server to allow external control of the OPTIMOD-PC cards from either a Telnet/SSH client or a custom third party application. All OPTIMOD-PC Presets and Mixer Controls are accessible and all commands are simple text strings

which are broadcast to all active clients to remain updated with current status.

Telnet/SSH:
RFC 318 compliant basic subset. Compatible with Windows Telnet and PuTTY Telnet clients.

TCP/IP Port user assignable.

Serial API provides complete remote administration over Serial port communication. The OPTIMOD-PC Service application hosts a Serial terminal server to allow external control of the OPTIMOD-PC cards from either a terminal client or a custom third party application. All OPTIMOD-PC Presets and Mixer Controls are accessible and all commands are simple text strings.

Compatible with terminal programs such as Windows HyperTerminal

and PuTTY VT-100 clients.

COM Port user assignable from COM1 to COM100.
