The Lab Gruppen C 28:4 is a compact 2U, 4‑channel installation amplifier delivering up to 4 × 700 W into 4 Ω for dependable performance in fixed systems. Each channel offers independently configurable Voltage Peak Limiter (VPL) and selectable input gain, giving precise control over headroom and loudspeaker protection. Suitable for both low‑impedance and 70/100 V distributed lines, it supports Hi‑Z operation at 70 Vrms / 100 V peak with 700 W per channel when all channels are driven, ensuring consistent output across multi‑zone and long‑cable runs.
With low distortion (<0.1% THD, 20 Hz–20 kHz at 1 W), a signal‑to‑noise ratio over 112 dBA, and an extended frequency response from 6.8 Hz to 34 kHz, the C 28:4 delivers clean, controlled audio. Strong current capability (12 Arms per channel) and excellent channel separation underpin reliable, high‑impact performance. NomadLink network control enables out‑of‑the‑box monitoring and essential remote management via DeviceControl, including channel mutes and power on/off for streamlined oversight.
Ideal for theatres, auditoria, houses of worship, conference centres and multi‑zone venues where efficiency, protection and consistency are key.
