Description

Adding comprehensive front-panel control features, the ALPS-2 audio leveler is ideally suited to dynamic operating environments, such as outside broadcasts, where instant local adjustment of sound parameters may be required.  A front-panel jog-wheel and LCD display provides intuitive simplicty with gain-reduction metering giving direct feedback to the user.

Features:

  • Top quality; 48-bit (24 bit i/o), 88.2 or 96kHz native-mode, also accepts 32, 44.1, 48kHz
  • Factory presets deliver exactly the results you need …fast
  • A properly integrated single-box solution with all features needed for broadcast
  • Maintains programme reliability - ‘pass-through’ relays for analogue and digital paths
  • Straightforward, clear and intuitive user interface
  • Security system prevents unauthorised tampering
  • Bright, Always-Visible LED bargraphs for audio confidence checks
  • Low audio latency (2.2 - 4 milliseconds), fast boot-up (<1 second), low power (7.5W)

BENEFITS:

  • Brings consistency to any programme stream 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 controls
  • Maintains programme path reliability – fail-safe mode if AC power or PSU fails

APPLICATIONS:

  • Control levels of Outside Broadcasts, news booths, unattended studios and ‘remotes’
  • Overload protection for STL, digital codec, PA and monitors
  • Normalisation at Ingest and Master Control – done right!
  • Sound level control for Television FM broadcast: Networks, Relay from satellite, Community radio & RSLs
  • Professional-level audio streaming, archiving and podcasting
