I. Read before use
The Alpha TDcontroller is designed to be used with the Alpha M4 and Alpha B1 speaker cabinets. Its
main functions are :
• To optimize the response of the system
• To split the signal into 3 frequency bands (LF, MF & HF)
• Active protection of the cabinets by dynamic audio signal processing (Temperature and
Displacement servo control)
• Reduction of amplifier overload (independent Peak limiter function on each channel)
Alpha TDcontroller also features :
• Global switchable output level
• Individual gain control on each channel
• High CMRR balanced input
• High current drive output stages
• User LF EQ
• Enhanced protection facility provided for additional safety margin when extended periods of
overload are anticipated
As with similar devices, the Alpha TDcontroller is intended to be inserted between the Audio source
(console, preamplifier, etc...) and the power amplifier.
WARNING : Sense lines MUST be wired in order to ensure the protection of your system. Failing
to do so may damage your speaker.
II. Front Panel
Most front panel functions and indicators are located inside 3 distinct windows : left-hand areas (with
upper label Eq & αLF) relates to functions and indicators dedicated to the B1 cabinet, while mid & right-
hand window (upper label αMF & αHF) contain indicators concerning servo control operation for the
Alpha M4
II.1. Wideband / Xover Push-button
