BENEFITS:

• Brings consistency to all programme streams without erasing musical dynamics
• Ends listener annoyance from over-loud segments such as commercials and shouting DJs
• Improves audibility and clarity of programme
• Eliminates overload distortion and damage forever
• Eliminates the inconvenience of unauthorised tampering with front-panel controls
• Maintains programme path reliability – fail-safe mode if AC power or PSU fails

APPLICATIONS:

• Sound level control for Radio and Television
• Normalise levels of news booths and unattended studios, ingest points, etc.
• Overload protection for STLs, digital codecs, PA and monitors
• FM broadcast: Networks, Relay from satellite, Community radio & RSLs
• Professional-level audio streaming, archiving and podcasting

FEATURES:

• Minimal feature set; very cost-effective yet fully professional
• Excellent quality – 96kHz and 88.2kHz native modes avoid unnecessary rate conversions
• Complete programme reliability – ‘pass-through’ relays for analogue and digital paths
• Factory presets deliver exactly the results you need for any application …fast
• No-tamper front panel (set-up by PC only)
• Bright, Always-Visible LED bargraphs for audio confidence checks
• Low audio latency (2.2 – 4 milliseconds), fast boot-up (<1 second). • Stereo or Dual-Mono modes
