תיאור המוצר
SR 4 is a DYNAB four-channel amplifier, perfect for driving Front/Rear, Front/Sub or as part of a multi-channel system, with independent, fully configurable, by-passable crossover sections.

1 Fully by-passable crossover FILTERS
2 Removable panel to hide and protect controls
3 Monoblock aluminium heatsink construction
4 Fanless convection cooling system
5 Strip fuse located on the control panel for easy replacement
6 Connections:
• Power supply terminals accepts 7 mm diameter (4 AWG) cable
• Speaker terminals accepts 4.5 mm diameter (8 AWG) cables
• Hi Level speaker and remote turn-on terminals equipped
with removable connectors with screw fastening
7 24dB low-pass filter when used in 3-channel configuration
8 Dual range high-pass filter (50Hz÷500Hz / 500Hz÷5kHz) for
multi-channel configurations
