Infinity 5760a wiring diagram – circuit diagram - 6 CHANNEL POWER AMPLIFIER

Output Power: 56W RMS x 4 and107W RMS x 2 channels @ 4 ohms; ≤1% THD + N
80W RMS x 4 and150W RMS x 2 channels @ 2 ohms; ≤1% THD + N
148W RMS x 2 and 287W RMS x 1 channels @ 4 ohms; ≤1% THD + N
Dynamic power: 117W channels 1,2,3,4; 163W channels 5,6 @ 2 ohms
Max Current Draw 34A @ 4 ohms
88A @ 2 ohms
89.5 @ 4 ohm bridged
Fuse: 2 x 30A
Idle Current 2.1A
GROUND CONNECTION
Connect the amplifier’s Ground (GND) terminal to a solid point on the vehicle’s metal chassis, as close to the amplifier as possible. Refer to the chart below to determine minimum wire-gauge size. Sand away any paint from this location; use a star-type-lock washer to secure the connection.
POWER CONNECTION
Connect a wire (see chart at right for appropriate gauge) directly to the vehicle’s positive battery terminal, and install an appropriate fuse holder within 18" of the battery terminal. Do not install the fuse at this time. Route the wire to the amplifier’s location, and connect it to the amplifier’s positive (+12V) terminal. Be sure to use appropriate grommets whenever routing wires through the firewall or other sheet metal. Failure to adequately protect the positive wire from potential damage may result in a vehicle fire. When you are done routing and connecting this wire to the battery and to the amplifier, you may install the fuse at the battery. The fuse value should be selected based on total amplifier-current draw.
REMOTE CONNECTION
Connect the amplifier’s Remote (REMOTE) terminal to the source unit’s Remote Turn-On lead using a minimum of 18-gauge wire. If your source unit does not have a remote turn-on connection, connect the amplifier’s (REMOTE) terminal to the vehicle’s accessory circuit.
The 5760a can be configured for 6-channel, 5-channel or 3-channel operation.
3-Channel operation: 5760a amplifier configured for 3-channel operation, where all of the channels are bridged for a subwoofer and a pair of component speakers.
5-Channel operation: The same as Figure 10, with the subwoofer output bridged to drive a single 4-ohm subwoofer, providing the speaker with more power.
WIRING DIAGRAM
CIRCUIT DIAGRAM
All tests to be done, unless otherwise specified, from 10Hz to 47KHz and 302Hz at 14.4V DC into 4 ohm loads and adjust the units gain so that with a .775 volt input signal the unit is at Its maximum rated output. All measurements will be done using an Audio precision system one and the supply voltage.
An A+ line voltage of 14.4V DC shall be applied to the unit under test for all measurements unless otherwise specified. The voltage applied to the unit shall
be measured at the power connection on the Amplifier.
Signal Source: Unless otherwise specified, all tests shall be conducted with the Audio Signal Generator output configured to be balanced, less than or equal to 50 ohm source impedance, and floating. The signal source "GND" shall be connected to the Amplifier PWR GND at the Amplifier.
Output Load: Unless otherwise specified, all tests shall be conducted with 4 ohm resistive loads having less than 10% reactive components at any frequency below 47KHz and 302Hz. Each resistor shall have a value that remains within 1 % while dissipating the rated output of the unit under test.
Power Indicator Green LED steadily illuminates for normal operation. Illuminates up Red LED blinks when protection circuitry is engaged, and during power up.
