Technical description:
- The Amplifier CSMA 1120 relies on DriveCore™ technology, which significantly reduces the number of internal components, enhancing reliability and increasing operational efficiency by up to 80% compared to previous designs.
- It offers four inputs (Mic/Line/RCA) with a single 120W output at 4 or 8 ohms (1 kHz, THD+N less than 0.5%). It also supports 70V and 100V systems without requiring an external adapter, making it suitable for distributed audio systems.
- It features a compact, fanless 1U design for completely silent operation, with a minimalist front panel containing only volume knobs for each channel, master level, and independent bass and treble controls. All knobs are surrounded by a light ring for easy visibility in low-light environments.
- It supports the JBL CSR-V wall controller via an RJ45 port using a standard Ethernet cable. It also features Priority Muting and Configurable Output Routing.
