The LEA Professional Connect Series CS124D is a four-channel, Class-D smart amplifier delivering 120 watts per channel across 4Ω, 8Ω, 70 V and 100 V loads, with the addition of fully integrated Dante & AES67 audio-over-IP networking. Sharing the same compact half-rack, 1U form factor as the CS124, the CS124D brings professional audio network transport to fixed-installation projects of any scale.

Dante connectivity is provided as a 4×4 implementation at 48 kHz (Multicast or Unicast), with AES67 interoperability configurable via Dante Controller — enabling seamless integration into mixed-manufacturer AoIP environments. The onboard Analog Devices Sigma 96 kHz DSP processor with 32-bit core delivers 48 dB/octave IIR crossover filters, eight bands of parametric EQ per channel and up to 100 ms of output delay, whilst LEA Cloud, the built-in WebUI and open third-party APIs provide comprehensive remote management over Wi-Fi or Fast Ethernet.

• 4× 120 W per channel @ 4Ω, 8Ω, 70 V & 100 V (selectable per channel)
• Dante: 4×4 at 48 kHz, Multicast & Unicast; AES67 via Dante Controller
• THD+N: 0.1% (20 Hz – 20 kHz)
• Frequency response: 20 Hz – 20 kHz, ±0.5 dB @ 4Ω, 8Ω, 70 V & 100 V
• S/N ratio: 102 dB (20 Hz – 20 kHz, referenced to 8Ω)
• 96 kHz DSP: 48 dB/oct IIR filters, 8-band PEQ, 100 ms delay per channel
• Balanced analogue inputs with selectable sensitivity: 26 dB, 34 dB or mic level
• Wi-Fi (AP & client) + 100 Mb/s Ethernet + Dante; LEA Cloud, WebUI & open API control

The CS124D is perfectly suited to houses of worship, corporate AV suites, hospitality venues, retail environments and educational facilities where Dante-networked audio distribution, flexible Lo-Z/Hi-Z amplification and cloud-based remote management are required in a single, compact unit.
