Ask SILICON CHIP . . . continued from page 102 honestly, I’m looking for something a little more sophisticated. Is there a Dev environment for the PIC that uses, for example, C? Would you recommend one that wasn’t BASIC? (T. B. Belconnen, ACT). • We asked the designer, Geoff Graham, to reply: If you are looking for a C programming environment for the PIC, you cannot beat the Microchip siliconchip.com.au MPLAB X Integrated Development Environment and their XC series of compilers. They are full-functioned and there are free versions available. However, be warned. Programming in the C language can be complex and difficult – that is why we developed MMBasic which is much easier to use. Reducing the gain of the headphone amplifier Is there a way to make the 2005 Studio Series Headphone Amplifier have zero gain? I love running it with the SILICON CHIP valve preamp however there is simply too much gain and volume. Still on the subject of valves, is there any chance a valve headphone amplifier will be published? As much as I’d like to try the Currawong I simply can’t afford the kit cost even though it’s cheap for a valve amplifier; $700 is simply too much for me (R. K., via email). • You can reduce the gain of the Nocontinued page 104 February 2015  103
