The Type 5612 Spectrum Shaper is used to modify the overall frequency response of acoustic and electroacoustic systems.

Its 36 individually regulated , narrow -pass bands with good roll-off attenuation also make it suited for use as a high-pass, low-pass, or a bandpass filter which can be adjusted for many applications.

• Thirty-six 1 / 3 octave band-pass filters each with its own attenuator
• Frequency range from 11 Hz to 45 kHz
• Filters conform to IEC 225-1966, ANSI S1.11- 1966 Class III and DIN 45 652
• Single filter notching of approximately 50 dB
• Roll-off attenuation better than 40 dB per octave
• Individual test point on each channel to aid adjustment
• Attenuator slider knobs to give a visual representation of the selected spectrum shape
