QUAD CHANNEL POWER AMPLIFIER:
Key Features
19-inch rack-mountable chassis (standard 2U height ~104 mm) for professional installation.
Class D audio output stage — efficient, lighter heat load.
Built-in limiter (ON/OFF) to protect speakers and amplifier from overload/clipping.
Toroidal transformer-based power supply for stable regulation and lower noise/hum.
Selectable input sensitivity (0 dBu = 775 mV & 4 dBu = 1.23 V) to accommodate different preamp levels.
Balanced (XLR) and unbalanced (¼″/6.3 mm phone) inputs. Outputs via Speakon 4-way and heavy-duty binding posts.
Comprehensive protection circuits: DC offset, short circuit, thermal, over-voltage, HF fault, clip monitoring.
Cooling via variable-speed DC fans with temperature sensing.
