• Powerful, yet unobtrusive level control • Simple, easy-to-use GUI programme for setup via PC and USB • Great audio quality. The same superb DSP module used in our professional ALPS range • Factory presets deliver exactly the results you need for any application …fast • Cost-effective yet with balanced analogue I/O and S-PDIF digital I/O • Desktop case; Half-width 1-U rack size, two can be rack-mounted side by side with optional rack mounting kit. • 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 • 96 or 88.2kHz native mode processing avoids multiple unnecessary rate conversions

Standard operating level -6dBu to +14dBu (+22dBu clip point) DIGITAL: S-PDIF (RCA/Phono); 32, 44.1, 48, 88.2, 96kHz sample rate. 16, 20, or 24 bits. Outputs: ANALOGUE: Balanced, ¼” jack [TRS]. Standard operating level -6dBu to +18dBu DIGITAL: S-PDIF (RCA/Phono); full input rate / half input rate and 88.2 / 96kHz selectable. Processing blocks: High-pass filter: Can be set between 3Hz and 110Hz 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 applications. Defeatable. Control: Setup is via PC only (GUI software supplied) and USB port (USB is on rear panel). Select a factory preset, modify it for less or more processing, set levels etc, save to Flash memory. Simplified operation of GUI (’Easy Mode’) does not require any expert knowledge. Every processing parameter, including all thresholds and time constants, can also be accessed and modified under PC control if desired for ‘Expert Mode’ setup. Power: 5V DC / 6 Watts. External 110V or 230V AC PSU supplied. Dimensions & weight: 44 x 217 x 228mm deep / 1.75” x 6.5” x 9” deep. Weight: 1kg / 2.2lbs Pro Versions For entry-level professional product (rack-mount, balanced analogue I/O, AES-3, XLRs) see our ALPS-1 product.
