A150.4D 4-Channel High Fidelity Class-D Amplifier A600.1D 1-Channel High Fidelity Class-D Amplifier A150.
Controls and Functions (150.4D): Turn On Mode: Signal: Senses audio signal on the speaker level inputs (>800mVp) and on the line level inputs (>45mVp) to turn on the amplifier. There will be a short delay in turn-off to accommodate silence between tracks. Offset: Senses the 6V BTL reference when the speaker level inputs are connected to the outputs of a BTL amplifier or head unit. Rem: Senses the remote turn on output of the head unit or to the car’s ACC circuit.
Turn-On Mode Signal Offset Rem Controls and Functions (A600.1D): The Turn-On Mode and Level control for the A600.1D operate exactly like the controls on the A150.4D. The Power and Protect LED functions are also the same as the 150.4D. Because the A600.1D is a single channel amplifier designed to drive low frequency speakers or subwoofers, the crossover controls are somewhat different and are explained below. High Pass 5Hz-40Hz: Adjusts the high pass filter frequency to any frequency between 5Hz and 40Hz.
Connections: A150.4D GND +12V REM GND: Connect to the metal part of the vehicle’s body. Scrape away paint to ensure a low resistance connection. Do not tin the wire with solder. +12V: Connect to the + terminal of the vehicle’s battery. You MUST install a fuse holder with a 60A fuse within 18” (45cm) of the battery’s terminal to protect the power wire and the car in case of a short circuit. Do not tin the wire with solder.
Connections: A600.1D Turn-On Mode Signal Offset Rem GND +12V REM GND, +12V, REM: Please see previous page. These connections are the same as for the A150.1D. You MUST install a fuse holder with a 60A fuse within 18” (45cm) of the battery’s + terminal. will be the sum of the inputs. If you have a stereo signal from your head unit, connect the left and the right output to the inputs. The output will contain the right and left signal. Observe proper polarity.
Remote Level Control (Optional): For one A600.1D and one RLC, plug one end of the RJ11 cord into the RLC and the other end into the amplifier. One RLC can control more than one A600.1D amplifier using a phone jack splitter like the one shown below. Plug one connector into the RLC and plug each of the other two into the RJ11 connectors on each of the amplifiers. To RLC To A600.1D To A600.1D If you have more than two A600.1D amplifiers and you want to use one RLC, you’ll need additional splitters.
Setup and Adjustments: Crossovers: The primary function of a crossover is to keep small drivers safe. The secondary function of a crossover is to provide an appropriate division of low and high frequencies to ensure an inaudble transition from one speaker to another. In order for a speaker to play high frequencies well, it has to be small and the diaphragm along with the rest of the moving parts must be lightweight. Small speakers, tweeters especially, aren’t designed to handle a lot of power.
