Lot #10: Used Rane RA27 Real Time Analyzer

Used Rane RA27 Real Time Analyzer ***Microphone Not Included*** The Rane RA 27 Realtime Analyzer is a single rack space unit providing 27 bands of realtime frequency / amplitude information in a 3-LED vertical band format. Broadband signals applied to either the Microphone or Line inputs of the RA 27 are divided into 1/3 octave increments by ANSI Class II filters. The outputs of these are applied to LEDs on the front panel to visually indicate the amplitude of each band. In operation, the RA 27 is used to visually judge the character of the Pink Noise signal received by the measurement microphone. The operator may now adjust a 1/3 octave equalizer for optimum response of a sound system based on the readings presented by the LED display. Front panel controls include an input Level sensitivity adjustment, calibrated in dB SPL, a Window switch which calibrates the sensitivity of the metering system, and a Pink Noise on/off switch. The MIC 1 is a flat-response microphone supplied with each RA 27 connects to the front panel Mic Input jack only. These factory tested microphones are flat to within 1 dB from 20 Hz to 16 kHz. An Aux Mic Input is provided on the rear panel, allowing the user to use a microphone of another type. To provide a reference for proper use of the RA 27, a pseudo-random digital Pink Noise generator is included in the unit. The output of the Pink Noise generator is flat within 1 dB from 16 Hz to 20 kHz and has a crest factor of 4.
