Inputs - Apogee AD-1000 Operating Manual

Note: The AD-1000 will work with any well regulated 12V DC Power source with an output current of 1300 mA
or greater. We recommend using linear type power supplies Direct connection to external 12VDC lead acid or
NiCad batteries will provide convenient portable operation. See page 43 for additional details on battery
power.

INPUTS

A. ANALOG INPUTS (two 3 pin female XLR connectors on rear panel)
Line Level:
• +4 dBu (Professional) nominal input level @ 10 k
CAL +4 Maximum input peak level (front panel gain controls at minimum, fully counterclock-
wise) +28dBu balanced, +24dBu unbalanced.
• –10 dBu (consumer) nominal input level.
Microphone Level:
• Minimum input peak level (Input Selector at Mic 40 and front gain controls at max): –54dBu
Balanced, –50 dB Unbalanced (up to 54dB of gain is available).
• Phantom Power:
Available in Mic Positions when Phantom Power Selector is enabled.
( 7mA available per channel to power condenser microphones.)
B. SYNC INPUTS (Two male BNC connectors on rear panel)
BNCs are paralleled for convenient looping to other units or termination (selectable termination).
BNCs will accept either balanced or unbalanced inputs.
WORD SYNC (WC):
32kHz to 54kHz Input Sampling Rates.
TTL or RS422 levels.
(input bridged by > 5 k
DIGITAL AUDIO SYNC:
32kHz to 54kHz Input Sampling Rates.
AES/EBU Format (termination selectable at SYNC SOURCE switch to110
by > 5 k
S/PDIF Format (input bridged by > 5 k
ANALOG VIDEO:
Black burst/Composite Sync/Composite Video.
NTSC (525line/59.94Hz); Monochrome (525line/60Hz); PAL (625line/50Hz).
(input bridged by > 5 k
C. OPTICAL SYNC INPUT: (Optical input connector on rear panel)
32kHz to 54kHz Input Sampling Rates.
S/P DIF or AES/EBU Optical Format.
In addition to Analog to Digital Conversion, the AD-1000 offers many Digital format conversion options.
Depending on the options installed, the following digital input options are available when the DIG position is
selected on the INPUT SELECTOR.
DIGITAL AUDIO INPUT STANDARD (UV22 processing for digital inputs available as an option)
32kHz–54kHz input sampling rates.
AES/EBU format (termination selectable at SYNC SOURCE switch to 110
or bridged by > 5 k ).
S/PDIF format (input bridged by > 5 k
