Model 6010
Four Channel
20-Bit Audio ADC
Data Pack
Revision 3.1 SW v1.0.0
MODULE OVERVIEW
The 6010 Four Channel 20-bit Analog to Digital Converter (ADC) converts four channels
of analog audio to two AES digital audio streams. Analog to digital conversion is
performed with 20-bit precision.
As shown in the block diagram below, four high impedance balanced analog audio inputs
enter the module on a high density 15-pin connector. The signals are buffered and passed
through gain adjustment circuitry before being converted to digital audio and sent to two
AES outputs (four copies of each) on rear BNC connectors. The ADC sample clocks may be
locked to an internal 48 kHz crystal controlled sample rate clock or locked to an external
AES3id reference from a BNC on the rear backplane.
Front panel indicators are provided for monitoring the external AES reference and the
four input channels of analog audio as well as power and CPU status.
Control of the module can be from one of the remote Avenue options or from the local
controls on the front of the module. Adjustments on the module include a rotary control to
set the analog input reference level and a set of switches to set the digital output
reference level. (Both of these reference levels determine the analog input gain.) The onboard microprocessor communicates with the frame for remote control via the Avenue
System Control module if installed. Module ID (slot location, software version and board
revision) and status information can be monitored by the frame System Control module
and read using the optional interfaces available. Alarms can also be enabled if desired.
Power is derived from the ± 12 volt frame power. It is regulated to the required voltages
for the module by on-board regulators. The module is fused with resettable fuse devices.
If a fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.

APPLICATIONS
Converting Analog VTR Audio Output to Digital
In the application shown below, a 6010 module converts the audio outputs of an analog
VTR to digital. Note that a 6030 Video Referenced AES/Word Clock Generator module
provides an AES clock reference for the 6010 module. In most video applications, it is
essential that AES sample clocks be locked to a video reference. Note also that the 6010
provides four copies of each AES output.
Analog Conversion from Video Routing Switcher to Feed Digital VTR
In this application, a 6010 module converts four channels of analog audio from a video
routing switcher to digital to feed a digital VTR. A 6030 Video Referenced AES/Word Clock
Generator module provides a video-locked AES reference for the 6010 module.

Converting Audio Outputs of Two Independent 2-Track Analog Tape Recorders
Even though it is a four channel device, the 6010 utilizes two separate 2-channel A/D converters. In this application, a 6010 module converts the audio outputs of two independent
2-track analog audio tape recorders to digital. Care should be exercised when connecting
the audio inputs to the 6010 to ensure that one machine is connected to inputs 1 and 2
and the other machine to inputs 3 and 4. This will ensure that the outputs of the two
machines will be paired correctly on the AES outputs of the 6010. Use of a 6030 module to
provide a video-locked AES reference for the 6010 is optional and is recommended in
video applications.
Driving a 6010 Using a Single-ended (unbalanced) Source
The 6010 has balanced transformerless inputs. The diagram below shows how to drive a
6010 using a single-ended (unbalanced) source.

INSTALLATION
Plug the 6010 module into any one of the ten slots in the frame and install the plastic
overlay provided onto the corresponding group of rear BNC connectors associated with the
module location. Note that the plastic overlay has an optional adhesive backing for
securing it to the frame. Use of the adhesive backing is only necessary if you would like
the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the backplane diagram of the module below for cabling instructions.
Connect an AES3id
reference input to the
Ref IN BNC if using an
external reference.
Connect output destinations to the four sets of
AES Out 1/2 BNCs.

MODULE CONFIGURATION AND CONTROL
The parameters for each Avenue module must be configured after installation. This can be
done remotely using one of the Avenue remote control options or locally using the module
front panel controls. Each module has a REMOTE/LOCAL switch on the front edge of
the circuit board which must first be set to the control mode you will be using.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections. The 6010 Parameter Table below summarizes and compares the various con-
figuration parameters that can be set remotely or locally and the default/factory settings.
If you are not using an remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section following the 6010 Parameter Table.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module be moved to a different cell in the frame at your discretion
without losing the stored information. Remote configuration will override whatever the
switch settings are on the front edge of the module.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
Avenue PC.
