DEUTSCH
FEATURES
• Professional 4-channel DSP-based class D power amplifier
• 4 x 240W (IPA 424 T) or 4 x 120W (IPA 412 T) @ 4 Ohm / 100V / 70V
• 4 balanced line inputs and 4 speaker outputs with terminal block connections
• User-friendly front panel design with signal, limit, protection, mute and bridge mode LEDs per channel
• Clip LEDs for the inputs and level controls for the outputs on the back
• On/off switchable auto standby mode
• Stereo/parallel/bridge mode selector per channel pair
• Toroidal output transformer per channel
• Low-impedance outputs, completely separated from the output transformers, for optimal audio quality in Low-Z applications
• DSP presets with HP and LP filter which can be activated via DIP switch
• Speaker protection circuits: DSP limiter, overcurrent, direct current, overheating, short circuit
• The REMOTE audio and control bus is based on CAN architecture (Controller Area Network) and enables interaction with future remote control
panels and paging microphones
• Slot for future optional expansion cards:
- An Ethernet expansion card providing access to all internal DSP settings and the analog input gain and increases the input dynamic range by up to 10 dB
- An Et Dante expansion card with the same functionality as the Ethernet expansion card plus Dante connectivity
• Fault relays with terminal block connections per channel pair
• Universal wide-range PFC switching power supply
• Temperature-controlled active cooling with low-noise fans in 2 zones
