The Model 235 incorporates all audio processing needs for AM broadcasting in a single, easy-to-use package. "Gain-riding" AGC is followed by variable low- and high-frequency EQ, 3-band compression, an asymmetrical, integrated limiter/clipper peak controller, and a low-pass function that satisfies NRSC or other "audio mask" specifications. A rear-panel RS-232 data port allows the processing presets to be programmed or updated by computer or modem; the necessary software is included. 
235's Features:
• One-box audio processing for mono-AM broadcasting
• Variable equalization and asymmetrical peak control
• NRSC-compliant & AMAX-certified
• Gated-AGC (Automatic Gain Control)
• 3-band Compression/Equalization
• Limiting and low-pass filtering
• Full remote control by computer or modem (RS-232 interface)
• Optional cutoff frequencies available (9kHz, 6.4kHz & 5kHz) 

235's Specifications:
• FREQUENCY RESPONSE:±1dB, 50Hz–9.7kHz* (taken through NRSC de-emphasis network and with processor EQUALIZATION set “flat”). * US NRSC (10kHz) version. Alternative cutoff frequencies for CCIR channel spacings and for various short-wave protocols are optionally available at slight additional cost.
• DISTORTION:Typically under 1% THD at any PROGRAM DENSITY setting, and at PEAK PROCESSING settings which maintain negligible clipping depth.
•  NOISE: Better than 60dB below full carrier modulation (assuming NRSC de-emphasis).
•FIXED PRE-EMPHASIS:The US version follows the “truncated” 75μs curve specified by the NRSC transmission standard. Alternative versions employ pre-emphasis appropriate to the cutoff frequency.
• VARIABLE EQUALIZATION HF: –3dB, 0dB (flat), +3dB, +6dB, MAX. (These figures are independent of, and in addition to, the NRSC or alternative fixed pre-emphasis. LF: –9dB, –6dB, –3dB, 0dB (flat), +3dB
• PROCESSING VARIABLES: PROGRAM DENSITY controls “blending” within the triband compression section, as well as the compressor release characteristic. Eight incremental settings range from a slow, single-band function to fast, fullyindependent 3-band operation. PEAK PROCESSING programs the action and interrelation of the peak limiter and clipper circuits in eight MIN to MAX increments
• INPUT:Active-balanced, bridging; accepts nominal program line levels between –15dBu and +15dBu.
• OUTPUT:Active-balanced, 200-ohm resistive source; delivers 0dBm to +15dBm into 600 ohms. •OUTPUT ASYMMETRY: Positive peak amplitude is continuously variable between +100% and +130%.
• REMOTE CONTROL PROVISION: An RS-232 serial data port (DB9 connector) allows all processing presets to be programmed by an IBMcompatible computer, directly or via modem. Supplied software runs under Microsoft Windows® 95/98.
• POWER REQUIREMENTS: 105-130VAC and 210-260VAC; 50/60Hz; 20W.
• SIZE AND SHIPPING WEIGHT: 23” x 16” x 2” (2U); 10 lbs/ 584mm x 406mm x 51mm ; 4.5 kg
