General Description
Do you have a paging and background music application
that would benefit from a low cost, one-box solution? The
DA 26 provides all of the tools needed to serve up to six
zones. For even greater flexibility in source selection and
zone distribution, combine the DA 26 with a Rane CP 52 or
CP 64 music and paging preamplifier. Many existing
solutions require installers to employ separate paging
preamplifier, dynamics processor, crossover, distribution
amplifier and remote-level-control devices. These systems are
expensive and require a lot of wiring, yet fail to meet all of
the requirements. The DA 26 provides all of the required
features in one compact package.
The DA 26 routes a mono program source and priority/
page source to as many as six zones. The mono program
source is processed by an Automatic Gain Control (AGC)
circuit featuring adjustable target level, ratio and attack/
decay.
The priority/page input features automatic signal detection
and remote zone assignment. A means of automatically
attenuating program music over a range of 0 dB to –80 dB
during a page allows mic/line mixing, talk-over or priorityreplaces-program operation.
Each of the six outputs distributes full-range, high-pass or
low-pass program music. Small bookshelf or hanging speakers frequently require bass enhancement. Bass enhancement is
achieved by adding bass to the full range response or by
employing a true bi-amp system. The DA 26 provides a 24 dB
per octave Linkwitz-Riley crossover that supports both bass
enhancement schemes. Wired remote level control ports allow
independent control of music amplitude in each zone.
Loudness compensation is automatic when a remote is used.
Remote level controls do not influence the priority/page level.
It is possible to control multiple remote level ports with a
single remote device. This allows one remote device to
control the level in multiple zones or both high-pass and lowpass outputs in a single zone.
