CT-4DAP-R2 - Overview

Sort channels, calibrate levels, and verify bandwidth. One person studio setup.
Forever end confusion over where each audio channel is being routed. Each of the four tone channels has a unique voice ID that will allow you to distinguish it from any other. External sync input for digital outputs.
Front panel switches allows complete control:
4 sources: 6-step frequency sweep, 1000 Hz, 400 Hz, and Microphone. All channels are in phase with each other.
4 selectable levels: 8 dBu, 4 dBu, 0 dBu, and -10 dBu; digital: -12 dBFS, -16 dBFS, -20 dBFS, and -30 dBFS.
Select Tones with Voice ID, Tones only, Voice ID only, and Mute.
Digital outputs operates at industry standard 48KHz and professional audio 96KHz digital rates.
Station ID Capable.


Flexibility And Consistency:
AES digital serial on BNC connectors with standard 75 Ohm output.
Convenient full size XLR audio connectors with balanced 100 Ohm analog audio output.
Internal frequencies are digitally synthesized and crystal controlled.
Digital outputs (48KHz/96KHz) can be locked to house reference.
Internal microphone lets you communicate over the test channels.
Natural voice ID function available with or without tones.
Ability to add station ID.
Battery operated from standard 9V cell for those times when you just can't get line power
Compact low-voltage (12VDC) design can be easily used with mobile equipment.
Handy Front Panel LED indicates when markers are being sent.
