SMR

The SMR is an external preamplifier for the SNN recorder, allowing external condenser microphones (typically AKG capsules of the CK5 or CK28 models) to be connected. It is equipped with a rotary input level control and a modulometer to indicate signal level. It is fitted with three different input high-pass filters to compensate for ambient room noise, as well as the possibility to lock the SN in playback mode by cutting the power to the recording circuits.
