SOTAbeams BOXA-DUAL Amplifier Kits

SOTAbeams BOXA-DUAL Amplifier Kits are ideal for incorporating into your own designs. However, for additional flexibility these amplifier and enclosure kits have been designed to allow your LASERBEAM-DUAL filter module (not included) to be used with all your favorite radios. They have a professional look that will compliment your shack. BOXA-DUAL enclosures have laser-cut gold panels which screw into a rugged extruded aluminum case.

BOXA-DUAL kits consist of a PCB that the filter module (not included) plugs into; together with an audio amplifier. The front panel features the CW Tuning LED (Sig) and Overload LED (Lvl) as well as a bandwidth switch (W/N) and volume control (Vol). The rear panel has 3.5 mm stereo jacks for audio in and out as well as a power jack for a DC supply (5-15 Volts). Power input is via a standard 2.1 mm power plug (supplied).

The board will drive headphones or a small speaker. By changing two resistors, audio output can be increased up to 1.5 Watts which will drive a larger speaker. Because the filter module is a plug-in unit you can swap between different LASERBEAM-DUAL modules depending on your application.

These kits use all through-hole components and are an easy build for a beginner. Build time is about 30 minutes.

IMPORTANT NOTES:

These kits:
* Include amplifier and enclosure
* Do not include a LASERBEAM-DUAL filter module
* Are not suitable for LASERBEAM-VARI or LASERBEAM-817 filter modules
