The 222 was originally developed as a
"post-processor" to ensure US broadcasters' compliance with FCC-mandated
occupied-bandwidth regulations. It incorporates a fast, asymmetrical
peak limiter, independent pre-emphasis-protection limiting, and a very
sharp-cutoff low-pass filter with proprietary overshoot control.
The
222 finds ready application in a wide variety of AM broadcast
situations. In addition to the NRSC 10kHz cutoff for medium-wave AM
broadcasting in the US, any high-frequency protection characteristic
between 4.5kHz and 15kHz can readily be accommodated to meet other
domestic and overseas needs. Though the 222 is intended to provide basic
final limiting, a "floating platform" release characteristic yields
sufficient program dynamics compression that often the unit can be run
"barefoot" between the console and transmitter with good results. (PWM)
control.
Features:
-Frequency Response (pre-emphasis defeated): ±1dB, 10Hz-8.7kHz (Euro MW)
-Distortion: Less than 0.2% THD, 10Hz cutoff with Peak Limiter OFF; less than 1% THD, 200Hz cutoff with Peak Limiter ON
-Noise: Better than 75dB below full carrier modulation
-Fixed Pre-Emphasis: Appropriate to the service and the cutoff frequency
-Input: Active-balanced, bridging; accepts nominal program line levels between -15dBu and +15dBu.
-Output: Active-balanced, 600-ohm resistive source; delivers 0dBm to +15dBm into 600 ohms.
-Output Asymmetry: Positive peak amplitude is continuously variable between +100% and +130% of the negative peak value
-Power Requirements: 210-260 VAC; 50/60Hz; 20W
