    Nice, but no low response for speaker output

    Overall: 3.5 out of 5

    This is a nice little unit, especially if you need something small and portable, including for field use. The sad thing I found out about it after I ordered it is that the speaker output (a Speaking type output) does not go below 100hz! That makes the unit next to useless in the field unless you use the XLR output, and then you'll need to amplify that signal. The XLR output has a 20-20kHz output range, but the speaker output only goes from 100Hz-20kHz. Otherwise a nice little tester for quick checking of frequency response ranges for you speakers. Use in co junction with an SPL meter and plot the frequency response of any speaker.
