Description

Used audio analyser including measurement microphone and certificate. The most important functions and features: • Red LED display for continuous level indication of the signal. • Centronics connection for direct printing via any LQ-compatible printer. • Front-panel microphone input with 48-V phantom power. • Two line inputs for stereo third-octave measurements and 1/3-octave analyses; the display can optionally show the sum or the difference. • Integrated A- and C-weighting filters. • Frequency mode with third-octave and 1/6-octave spectrum analysis via microphone or line inputs. • DN3600 interface to support automatic equalizer functions. • Display range, level and response time can be quickly adjusted. • Switchable display as peak or average value, supplemented by a peak-hold function. • Built-in signal generator for sine tones and band-limited pink noise. • Test signal bursts and frequency sweeps with automatic acquisition of measurement data. • 32 memory locations with options for accumulating and overwriting data. • Stored measurements can be compared and recalled. • Time measurement mode for determining RT60 (reverberation time), Leq (equivalent sound pressure level) and Let (equivalent dose). • Efficient internal power supply with automatic detection of the supply voltage. Frequency range: 5 Hz to 40 kHz.
