Audessence AM PRO-1 AM Digital Audio Processor.
The Audessence AM PRO-1 is a complete air-chain audio processing system for AM radio stations. Adjustable input pre-filtering (lowpass and high-pass) pre-conditions audio to prepare for aggressive 'brick-wall' low-pass filtering later and avoids wasting modulation percentage on inaudible sub-bass components Unsurpassed Audessence AGC developed for the professional Audessence levellers keeps programme level as consistent as desired Programme compression, limiting, pre-emphasis and clipping for optimum loudness and coverage increase All this plus enhancement features for brightening and clarifying your programme.Adjustable Low-Pass filtering meets all international and national broadcasting specifications including ITU and NRSC (4kHz to 15kHz nominal).
FEATURES:
- Complete digital air-chain processing for AM radio broadcasters in a compact package
- Adjustable input High-pass filter 3Hz to 200Hz
- Phase rotator to reduce programme asymmetry
- Advanced AGC as used in our ALPS levellers offers unsurpassed rapid control of levels
- Independent programme compression stage
- Presence enhancer to brighten programme and cut through noise
- Choice of pre-emphasis to meet national requirements including NRSC
- Adjustable low-pass filter for all applications
- Fco 4.5kHz to 10kHz
- Sophisticated peak control dramatically increases loudness without digital grunge
- Positive peak asymmetry up to 145% (where legal)
- Factory presets deliver exactly the results you need for any application …fast
- No-tamper front panel (set-up by PC only: GUI software, USB and RS-232 ports provided)
- Bright, Always-Visible LED bargraphs for audio confidence checks
- Low audio latency (4 milliseconds)
- Fast boot-up (<1 second).
Frequency Response (All filters set for minimum action):
DIGITAL-DIGITAL: 20Hz-14.9kHz /-0.1dB
ANALOGUE-ANALOGUE: 20Hz-14.9kHz /-0.2dB
Noise:
DIGITAL-DIGITAL (rms 20Hz-20kHz): <-110dBFS
ANALOGUE-ANALOGUE: (rms 20Hz-20kHz): <-75dB ref: Limit point 8dBu
Distortion:
DIGITAL-DIGITAL (6dB limiting): <-90dB / 0.003% THD
ANALOGUE-ANALOGUE (6dB limiting): <-70dB / 0.03% THD
Inputs:
ANALOGUE: Active balanced, 10k (bridging), standard operating level -6dBu to 14dBu (clip 22dBu)
DIGITAL: AES-3 (XLR); 32, 44.1, 48, 88.2, 96kHz sample rate. 16, 20, or 24 bits.
Output:
ANALOGUE: Active true balanced, standard operating level -6dBu to 21dBu
DIGITAL: AES-3 (XLR); full input rate / half rate.
Processing blocks:
High-Pass: 3dB Frequencies 3Hz [DC block], 20Hz, 30Hz, 45Hz, 75Hz, 90Hz, 135Hz, 150Hz, 180Hz.
Phase Rotator: Cancels asymmetry in certain programme material
Gated AGC: Capture range 40dB ( /-20dB); maximum positive gain can be set.
Advanced AGC enables faster, programme-dependent operation.
Compressor: Nominal 2:1 slope
Presence Enhancer: Boosts selected frequencies for intelligibility and / or brightness.
Limiter: look-ahead limiters plus NCDCS anti-aliasing clipper.
Low-Pass Filter: Cut-off frequency 4.5kHz, 5kHz, 5.5kHz, 6kHz, 7.5kHz, or 10kHz NRSC compliant
HF Limiter: 50us or modified 75us (NRSC) emphasis curve
Tilt Corrector: Reduce tilt due to LF problems in some transmitters. Increases loudness.
Control:
Setup is via PC GUI only. Select a factory preset, modify it, set levels etc, save to Flash memory.
USB on front panel, plus RS-232 on rear panel. ASCII Text based command format. Choice of ‘Easy’
mode (simplified, with Wizard), or Expert mode for GUI control.
