TC1280 STEREO DIGITAL AUDIO DELAY
The TC 1280 STEREO DIGITAL AUDIO DELAY is a high resolution audio delay based on the
proprietary converter technology that made the TC2290 Dynamic Digital Delay a world
standard in the recording industry. Two independently controlled audio channels make the
TC1280 ideally suited for any system requiring precise control over audio delay. Uses include
concert delay towers, balcony delay in theatres, mastering delay, audio for video format
conversion, matching of video processing delays, etc. anywhere that high quality time delays
are desired with minimum effect to signal quality.
FEATURES:
• No degradation of signal quality .The TC digital converter technology has been acclaimed
as being "very musical and warm".
• Soft HF roll off: -3dB @ 25 kHz and -12 dB @ 33 kHz allows ALL the signal to pass thru the
device.
• Dynamic range > 100 dB is excellent for live sound performances.
• Absolute stereo phase linearity within 2 microseconds.
• Delay time increments adjustable down to 5 microseconds for exact adjustments needed
when aligning speaker driver components.
• Expandable memory up to 2 x 10 seconds.
• Front panel controls are lockable for permanent installation.
• Remote control possible via MIDI or dedicated switches. (TC0050 footswitch allows access
to presets).
• Delay times may be displayed and adjusted in time, or distance (meters or feet), or video
frames (25half or full frame, and 30half or full frame).
• Automatic relay bypass of audio should there be a loss of power.
• Non-volatile memory of delay time settings in 4 presets.

UTILITY LIST
UP
<POWER> Mains power on/off switch. During start up, the unit will display the
software revision number. Note: the audio signal input is connected
directly to the output by a relay when power is not on.
LEFT INPUT Input gain of left channel. -10dB to +10dB.
RIGHT INPUT Input gain of right channel. -10 dB to + 10 dB.
LEFT OUTPUT Output volume of left channel. 0dB to mute
RIGHT OUTPUT Output volume of right channel. 0dB to mute
PPM Peak program meter for both left and right channels. When "DELAY
LINE" is adjusted for left, the PPM will display the left channel.
When "DELAY LINE" is adjusting for right, the meter will display the
right channel. When "DELAY LINE" is adjusted to L= R (left = right)
the PPM will display the audio channel which is highest.
OVERLOAD The OVERLOAD LED +3 will always display a overload on either
left or right channel.
BYPASS Delay bypass on left and right channels. Sets the delay time to 0
seconds. (This is not a relay bypass)
MUTE Mutes both channels at output.
MONO Mixes left and right inputs to a mono signal.
DELAY LINE Switches between 3 positions L, R or L=R. Left channel (L) displays
the delay time of left channel. Right channel (R) displays the delay
time of right channel. Left = right (L= R) displays the delay time of
both channels alternatively.
DELAY DOWN Decreases delay time for the displayed channel
(or both if L=R displayed).
DELAY UP Increases delay time for the displayed channel
(or both if L=R displayed).
SHOW DISTANCE
METRE
Press the "DELAY LINE" and the "BYPASS" keys simultaneously in
order to get the delay displayed in meters. Press the "DELAY LINE"
or "DELAY UP" / "DELAY DOWN" to get back to time display.
Note: If UTILITY PARAMETER 4 is set to VALUE 1 you can adjust
the delay time in SHOW DISTANCE mode
SHOW DISTANCE
FEET
As above, but press the "DELAY LINE" and the "MUTE" keys
simultaneously in order to get the delay displayed in feet.
