Features
CEA-2006 Compliant: CEA-2006 is a new system of testing & measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic Distortion (THD) plus noise, and at a frequency range of 20 Hz to 200 Hz, when applicable. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. The Infinity Reference 1300a under CEA-2006 regulations is rated at 200 Watts RMS x 1 channel with a 85dBA signal to noise ratio.
Mono-Power Amp Design: The Infinity Reference 1300a is designed with specific features to power your subwoofers with a frequency range between 11-330 Hz. This amplifier is not designed to power a full-range speaker.
Class D Design: The Infinity Reference 1300a is equipped with a high-performance Class D switching power supply, which is more efficient than traditional class AB power supplies, and draws less current from your vehicle's charging system.
Protection Circuitry: The amp features 4-way protection, and will shut itself down in the following cases:
- DC Output: DC voltage is detected on the amplifier output
- Temperature: Amplifier is overheated
- Over/Under Voltage: Voltage at the +12V (Battery) terminal is less than 8.5V or more than 16V
- Short Circuit: Short circuit in speaker or speaker wire
Power and Protection LEDs: The amplifier features a Power and Protection LED on top of the unit. The Power LED illuminates Green when the amplifier is supplied power. The Protection LED will illuminate Red when the amplifier goes into protect-mode.
Controls
Input Level: Rotary control to match the level of the preamp input signal
Low Pass Filter: The 1300a has a variable 12dB per octave, 32-320Hz low pass filter to prevent unwanted high-frequencies from reaching your subwoofers so they can play deeper and louder.
Bass Boost: The Bass Boost control allows you to enhance the bass output of your system at 50Hz up to 6dB.
Optional Remote Level Control: The amp has an RJ-11 jack for use with the optional remote sub-level control module. The control module includes a 19.5' cable to connect the remote to the amplifier. This sub-level controller allows the subwoofer level to be adjusted from the listening position.
Connections
Preamp Output: 1 pair of gold-plated RCA jacks (amp provides a non-filtered signal for daisy-chaining additional amplifiers).
Preamp Input: 1 pair of gold-plated RCA jacks.
Remote Level Control: RJ-11 jack for use with the optional remote sub-level control.
IMS Input: This port is designed for future Infinity expansion products.
Speaker Output: 4 Set screw terminals for connecting speaker wires; handles up to 8 gauge (16 gauge minimum recommended).
Note: There are two sets of terminals to make it easier to connect multiple subwoofers. The terminals are connected internally in parallel.
Power:
- +12V: Set screw terminal for power wire from battery; handles up to 4 gauge wire (8 gauge minimum recommended)
- Remote: Set screw terminal for remote turn-on lead; handles up to 8 gauge wire (18 gauge minimum recommended)
- Ground: Set screw terminal for ground; handles up to 4 gauge wire (8 gauge minimum recommended)
Fuses: 3 Slots for 20A ATO fuses (installed)
