The Dorrough 10-AE Analog Loudness Meter +43dB is a single-channel version of Dorrough's standard 40-A loudness meter with a display scale allowing 43dB of headroom in 1dB steps and Phoenix (euroblock) connectors. The headroom scale is identical to the AES/EBU Digital Standard.
This meter provides access phase correlation, peak hold, sum/diff, and reference mode allowing 0 reference setting to .1dB accuracy, directly or with the optional remote control. Rack mounting is required.
