RC1 Leveliza

Key Features

  • Function | Transparent audio levelling
  • Channels | Dual-channel (2 independent channels)
  • Dynamics | Preserves natural dynamic range
  • Signal Analysis | Analyses dominant loudness components over time
  • Fast Response | Rapid reaction to sudden level increases
  • System Protection | Prevents distortion and protects sound systems
  • Operation Type | Level control without compression or limiting

Product Overview

The RC1 Leveliza is a dual-channel audio levelling processor designed to keep sound levels consistent while preserving the natural dynamics of music. Rather than compressing or limiting the signal, it transparently controls average loudness, helping to protect sound systems and prevent distortion caused by sudden level increases.

The unit continuously analyses the audio signal and reacts quickly to unexpected peaks, making it suitable for venues and live sound systems where reliable level control is required. It features balanced XLR inputs and outputs for both channels and is housed in a 1U, 19-inch rack-mount enclosure approximately 250 mm deep. Power is supplied via a standard IEC C14 inlet, operating on 90–264 V AC at 47–63 Hz.

The RC1 Leveliza is commonly used as a system safeguard, maintaining stable output levels without audibly affecting sound quality.
