details... |
| ETF supplies a high performance calibrated
electret condenser microphone and preamplifier for use in
sensitive applications. The RS analogue or digital SPL meter
may be used for ETF as well. This will not supply the same
accuracy as the unit sold here but is recommended for applications
where critical adjustment of frequency response is already
done or not necessary.
