Recently, a problem has been observed when using the SHURE SM93 lavalier microphone. When plugged in directly to the F8, the preamp can not be removed by pushing the release button. This is due to the SHURE SM93's latch hole not being fully compliant with the IEC standard.
To avoid this problem, please insert a microphone cable between the preamp and the F8's XLR jack.
