Digital Audio Processing at a REVOLUTIONARY Price!

Solving Audio Level Problems Completely.

---

Superb digital programme levelling for podcasting and streaming; plus contribution studios,  news, and sports applications

Also perfect for mic processing; includes high-pass and de-essing functions [requires insert point in mixer]. 

Two channels (Presenter and Guest) can even be processed simultaneously by one PodBlaster

• Allows every presenter the freedom to concentrate on the content

• Improves audibility and clarity of programme

• Eliminates overload distortion and damage
  forever

APPLICATIONS:

• Audio level 'auto-pilot' for Podcasting and Streaming

• Outside Broadcasts, news booths, contribution studios and remotes

• STL, digital codec, PA and Monitor overload protection

• Mic processing for talks and contrib studios

FEATURES:

• Powerful yet unobtrusive level control

• Simple, easy-to-use GUI programme for setup via PC and USB - plus 9 factory presets to get you going

• Great audio quality.  The same superb DSP module used in our professional ALPS range

• Stereo (linked) or Dual-Mono operation: can process two channels independently

• Cost-effective yet with genuine balanced analogue ports - and S/PDIF digital output AND S/PDIF digital input

• Desktop case; half-width 1-U rack size, two can be mounted side-by-side with optional rack-mount kit

• Bright, Always-Visible LED bargraphs for
  audio confidence checks

• Low audio latency (2.2 - 4 milliseconds), fast
  boot-up (<1 second), low power (6W)

Processing blocks:

Input HPF (adjustable) and LPF

Gated AGC: Capture range +/-20dB; maximum positive gain can be set.
Advanced AGC enables faster, programme-dependent operation. Defeatable.
Compressor: Nominal 1.5:1 slope and 4dB maximum boost of low levels.  Defeatable.
Wide-band Limiter: Zero overshoot 1.3ms look-ahead zero clipping. Defeatable.
HF Limiter: Protects 50us or 75us emphasis curve for FM broadcast and de-essing applications. Defeatable.

Control:
Setup is via PC only (GUI software supplied) and USB port.
Select a factory preset, modify it for less or more processing, set levels etc, save to Flash memory.  Simplified operation of GUI does not require expert knowledge.
Every processing parameter, including all thresholds and time constants, can also be accessed and modified under PC control if desired for 'expert' setup.

Power:
5V DC / 6 Watts.  External 110V or 230V AC PSU supplied.
