Четириканален усилвател Class D с DSP: 120 W на канал към 4 или 8Ω, 240 W в Bridge режим към 8Ω или 70/100V линия. Mic/line входове с +48V фантомно захранване; Sigma DSP с WebGUI.
Характеристики
- A 4-channel DSP-equipped amplifier that delivers 120W per channel
- Supports balanced / unbalanced mic / line-level inputs and drives 4 / 8-ohm low impedance or 70 / 100V line (in Bridge mode) loudspeaker systems
- +48V phantom power supply
- Built-in WebGUI-configurable Sigma® DSP allows speaker EQ, 5-band EQ, compressor, delay, limiter, and up to 20 presets for precise tuning and system protection
- Class D design assures high power efficiency
- PFC (Power Factor Correction) Power Supply – Fly-back power supply design with PFC ensures efficient operation while reducing energy consumption
- Integrated protection circuit – Protects the system from damages caused by Amp short circuit, Amp output over/under voltage, high-frequency overload, and overtemperature
- Customizable Auto Standby mode – Amplifier automatically switches to “sleep” when the signal level falls lower than -40 / -50 dBu for 10 / 15 / 25 minutes
- Solo function – Allows users to isolate and monitor a particular input / output
- Expansion slot for add-on expansion card – Install AP901 2-CH Dante Expansion Card to make the sound system compatible with Dante network or AP902 2-CH Mic/Line Pre-AMP Expansion Card to receive two more channels of mic / line input signals
- Fanless – Avoids fan noise and prevents dust from building up
- Supports VK Control System via RS-232 and Ethernet connection
- 1U rack mountable enclosure
- Firmware upgradable
