Silicon Chip September 2017
In this month's Silicon Chip Magazine September edition, build an Active Crossover for Loudspeakers.
This Stereo 3-Way Adjustable Active Crossover can be integrated into a
2-way or 3-way Active loudspeaker system, to set the crossover frequencies
and really enhance your listening pleasure. The crossover points and levels
for tweeter, midrange and woofer are fully adjustable with separate controls
for each driver. The unit also features an overall volume control, as well as
balance control. The technical and design theory for the unit is fully explained
and the project uses readily available parts.
Also in this month's projects, build a Superhet IF Alignment Unit using Direct Digital Synthesis. This unit is based on the Micromite Signal Generator project and makes aligning the IF stages of a superhet easy, whether they are valve or transistor based. For the Arduino enthusiast, there are plenty of hands-on guides and projects, including the second part of the Arduino Data Logger with GPS project, plus an introduction to using the ESP8266 to log data onto the net from a remote location, finally a look at the AD9850 DDS Module. All projects come complete with circuit diagram and electronic parts list.
In this month's main feature a detailed look at the Cassini mission to Saturn. A look at the trip and some of the information this remarkable mission has returned. Also this month, the Electronex exhibition is on in Melbourne this year, a look at what's happening and some of the exhibitors displaying their products at this year's exhibition. Plus all the regular columns, including the Circuit Notebook, Serviceman's Log and Vintage Radio are included, providing stacks of great reading.
