- Professional Digital Audio Test Equipment –
The CT-MADI signal generator makes it possible for one person to setup or verify a
MADI communication link easily, quickly, and accurately. The unit produces a
hands-free audible sequential voice ID for each channel, eliminating the need
for external generators or extra personnel to switch between sources. In
addition to the voice ID’s, the CT-MADI includes four tone sets that will
verify frequency response and level accuracy. MADI outputs are available on both COAX
and FIBER. The unit can be locked to a variety of external references and
generates a re-clocked Word clock.
In addition to a MADI output, there is
a Reference AES DAR output and AES Audio output with the same signal that is on
the MADI channels.

WORD Clock Output: Word clock output 48KHz will drive 2.5VP-P into 75 ohms. Internal jumper
to select 4.5VP-P output.
Tones: 4 tones selectable:
1)
1KHz @-20dBFS, Level can be set to -18dBFS with internal jumper.
2) 400Hz @-20dBFS, Level can be set to -18dBFS with internal jumper.
3) Frequency SWEEP:
Eight stepped tones: 75, 125, 250, 500, 1000, 2000, 4000, and 8000Hz. Duration
1-sec (or 0.5-sec with internal jumper) each continuously repeating. Output
level is exactly -20/-18 dBFS with 19-bit resolution and 20-bit compatible.
4) LEVELS:
