Speaker-In inputs with 1.6-40Vrms sensitivity and integrated Universal Speaker Simulator (USS) technology enable correct connection to head units with speaker load detection, including OEM and factory head units. Pre-In inputs cover 0.32-8Vrms. Balanced input circuitry on both Pre-In and Speaker-In provides high noise rejection for clean signal transmission. Automatic Remote Turn-On\/Off is triggered by OEM radio speaker output at 1.5V DC.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eFull set of controls includes adjustable input levels, front and rear high\/low-pass crossover filters (50-4000Hz, 12dB\/Oct.), and 0-9dB bass boost at 50Hz. Full-range pre-outs are provided from the front channel. Operating supply voltage range is 6.5-16.5V DC with a nominal 2 x 20A fuse rating. Elegant status LED, solid machined terminal block, and removable top panel. Dimensions are 290 x 252 x 50mm.

Many modern factory head units monitor the presence of a speaker load on their outputs and will only enable audio output if a low-impedance load is detected. Without USS, connecting a high-impedance amplifier input directly to the factory head unit speaker output can cause the head unit to mute or error. USS resolves this, enabling clean OEM integration without additional adapters.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003cstrong\u003eDoes the DP 4.300 require a separate remote wire for turn-on?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\"\u003eNot necessarily. The ART (Automatic Remote Turn-On\/Off) feature activates the amplifier from the OEM radio speaker output signal at 1.5V DC, eliminating the need for a dedicated remote wire in factory head unit integration installations.
