Compact Loop Driver With Desktop
Microphone
|
| Overview |
The CLD1
Compact Loop Driver is designed for counter systems and
small area perimeter loop systems. Measuring only 5" x
2.9" x 1.4" and with an output current of 2.4 A (RMS), the
CLD1 is the smallest and highest performance amplifier in
its class. Based on proven and highly reliable technology
it is backed by a 5 year warranty and Listen technical
support. The CLD1 offers certainty of performance and the
lowest lifetime cost available
Audio quality is ensured with metal loss correction (MLC)
combined with usual high standards of design. The CLD1 is
designed for flexibility and convenience, featuring two
separate microphone inputs with independent level
controls, one of which can be configured as a line input.
All cable connections are made on a single face of the
unit, adding flexibility and further simplifying
installation |
