The SAGE-300 will enhance and balance the tone quality of your communication repeater system by enabling you to cut or boost, by 10 dB, three audio speech bands. The low frequency cutoff is at 250 Hz, which prevents sub-audible CTCSS tones from being passed on for equalization. Measured at the - 3dB points, the audio speech passband is from 275 to 4,400 Hz. Three separate trim potentiometers enable the user to boost the amplitude of the low (275 - 1,000 Hz), mid (1,000 - 2,600 Hz), and high (2,000 - 4,400 Hz) bands.

Ideal for HF, VHF, UHF and link transmitter applications, the SAGE-300 will compensate for the short comings in audio section of your communications system. Many microphones, link radios, and transmitters, have less then optimal audio characteristics. Audio degradation problems are compounded in linked or interconnected systems. The SAGE-300 enables you to easily balance your audio to ensure the highest quality of communications. Audio performance is significantly improved on all modes of modulation, including: SSB, AM, wide and narrow band FM. Total harmonic distortion is less than 0.01% @ 1 kHz.

When used for telemetry purposes it will allow the audio path to be bandwidth limited and it will improve DTMF twist problems associated with interconnected systems. The SAGE-300 also enables users to adjust Narrow Band FM radios to meet the new EIA de-emphasis specification (6dB per octave de-emphasis curve). Many receivers being used today do not meet this specification, which results in un-natural and hard to understand audio.
