Thank you for purchasing the Pyle Red Elite Class-D amplifier. Rest assured you have purchased a quality product designed and engineered to give you many years of uncompromised musical service. The Pyle Class-D amplifier has been designed using the latest in electronic technology available today. This is due to the noise introduced into the signal by the switching speed of the power supply, which must be filtered out of the audio signal. The power supply incorporated into Pyle Red Elite amplifier is a DC to DC switching power supply designed to have adequate headroom for even the most demanding peak and dynamic range found on today's CDs and recording. This mono subwoofer amplifier is the result of advanced high speed switching technology that overcomes the less-efficient Class-D design. the Pyle Red Elite Class-D amplifier reflects your true appreciation for powerful bass reproduction in the mobile environment. This amplifier is designed for low-frequency information only and it is not capable of reproducing any mid/high-frequency information. table of contents general features features and specifications system wiring 2 3-4 5-6 7 8 PLAD3300D PLAD3300D amplifier and installation protection circuitry and troubleshooting general features PLAD3300D 2400W Mono Block MOSFET Digital Power Amplifier · Mono Block Subwoofer Amplifier · 1 Ohm Stable1 · MOSFET Power Supply · PWM (Pulse-Width-Modulation) System · Glass Epoxy PCB · Gold Plated RCA Inputs for Line Input & Bypass Output. · Gold Plated Terminals for Speaker Output and Power Input. · Thermal, Overload and Short Protection · Variable Sub-sonic Filter (15Hz~40Hz, 24dB/Octave) · Variable Low-pass Filter (20Hz~250Hz, 24dB/Octave) · Phase Control 0-180 degree · Remote Bass Control · Input Impedance : 10K Ohms · Soft Turn On/Off · Advanced Protection Circuitry · S/N Ratio:>90dB · Heavy Duty Power Coated Heatsink · Blue LED Level Display · Dimensions: 10. 9"(W) x 2. 7"(H) x 15"(L) 2 fC lea sas t- Du M OeN s B aOnC Kd A Mc PoL InF ItE rR oP Ll As3 0 0 0 D rOL PLAD3300D power LED protection LED remote bass boost low pass frequency control line level outputs line level inputs input level control sub sonic control phase shift switch 6 3 speaker connections power fuse power terminals fC lea sas t- Du Mr OeN Os B LaO nC Kd A McP oL InF ItE r oP LlA s3 0 0 0 D R Class-D design power supplies crossover low pass filter PLAD3300D Mono channel amplifier high pass subsonic filter output power @14. 4v DC, 1KHz RMS Power at @4 Ohms Stiffly regulated PWM power supplies. MOSFET switches maintain RMS Power at @2 Ohms rated power over a wide range of battery voltages. Check that there is battery power on the terminal. If it is lit, shut off amplifier briefly and then repower it. Protection LED comes on when the amplifier is powered up. Check that the volume control on the head units is turned down low. Remove speaker leads, and reset the amplifier. if the protection LED still comes on, then the amplifier is faulty. Check that the minimum speaker impedance for that model is correct. Check that there is good airflow around the amplifier. in some applications, an external cooling fan may be required. Distorted sound Check that the level control(s) is set to match the signal level of the head unit. [. . . ] Distorted sound Check that the level control(s) is set to match the signal level of the head unit. Check that all crossover frequencies have been properly set. This is always caused by a poorly-grounded RCA patch cord. 8 High hiss or engine noise(alternator whine) in speakers. [. . . ]
