SPECIFIKACIJE:
Frequency Response (processing bypassed)
50Hz - 20kHz, ±0.25dB
Output Cutoff Response
-
Nominal Frequencies: menu-selectable 4kHz, 5kHz, 6kHz, 7kHz, 8kHz, 9kHz, 10kHz (US NRSC), 12kHz, 15kHz
-
Filter Characteristic: 143-coefficient FIR filter with phase and overshoot compensation; ±0.5dB, 50Hz to 0.95x nominal cutoff frequency; approx. –15dB at cutoff; > –50dB at ≥1.04x nominal.
Pre-Emphasis
Selectable flat, or ‘truncated’ US NRSC preemphasis curve scaled to the cutoff frequency
Distortion (processing bypassed)
-
Analog I/O: <0.02% THD (ref: +24dBu I/O)
-
AES Digital I/O: <0.002% THD (ref: 0dBFS I/O)
Signal-to-Noise (processing bypassed)
-
Analog I/O: >105dB (ref: +24dBu I/O)
-
AES Digital I/O: >120dB (ref: 0dBFS I/O)
-
Analog: active-balanced (XLR) accepts line levels from –15dBu to +15dBu; +24dBu clipping
-
AES Digital:(XLR) accepts line levels between -30dBFS and 0dBFS at sampling rates from 32kHz to 96kHz
-
IP Streaming: accepts all Icecast/SHOUTcast MP3, Ogg and AAC streams
Program Line Outputs
-
Analog: active-balanced (XLR) delivers –12dBu to +15dBu for 100% symmetrical modulation; +24dBu clipping, 200Ω source
Positive Peak Enhancement
Intrinsic asymmetrical, positive-going peaks may be selectively limited in 1% steps from 100% to +130%
Program Signal Latency (Delay)
Approx. 3.75ms
Network Port
TCP/IP network connection (RJ45) for remote setup/operation and in/out audio streaming; full support for SNMP control
GPIO Ports
3 GPI, 3 GPO w/ assignable functions and logic polarity
Headphone Jack
Front-panel (TRS) 3.5mm
Internal Test Tone Generator
20Hz-20kHz; variable frequency and level
Alarms
Local (GPIO) closures, browser interface, SNMP and SMS/email alarms for analog, digital and stream audio loss; maintains daily, weekly, monthly logs
Scheduler
Dayparting is simplified with an onboard real-time clock and preset-selection programming.
Audio Processing

AGC: ±15dB capture range; gated with dual-rate‘windowed’ operation
-
Leveling: variable ‘syllabic’ 2:1 compression
-
EQ: 4-section parametric
-
Bass ‘Punch’: variable bass enhancement
