JBL GTO 752 car audio amplifier Service manual
The JBL GTO752 is a 2-channel power amplifier with 75W RMS x 2 channels @ 4 ohms and ≤1% THD + N, 110W RMS x 2 channels @ 2 ohms and ≤1% THD + N. It also features a 12dB/octave crossover, variable from 32Hz to 320Hz. The amplifier includes a Bass-Boost control to set bass according to preference. The GTO752 is protected from short circuits in the speaker wires and overheating. It features a status LED to inform the user when the amplifier is on, and a protect LED to indicate fault conditions like battery over/under voltage, short circuit or the amplifier is too hot.

GTO752 CAR AUDIO POWER AMPLIFIER OWNER’S MANUAL
Installation Warnings and Tips
• Disconnect the negative (–) lead from your vehicle’s battery.
• At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.
• Choose a safe mounting location away from moisture.
• Make sure there is sufficient air circulation at the mounting location for the amplifier to cool itself.
• Mount the amplifier, using the supplied hardware.
Specifications
• 75W RMS x 2 channels @ 4 ohms and
≤1% THD + N*
• 110W RMS x 2 channels @ 2 ohms and
≤1% THD + N*
• THD + N: 0.07% (rated power @ 4 ohms)
• Signal-to-noise ratio: 90dBA
(reference 1W into 4 ohms)*
• Signal-to-noise ratio: 108dBA
(reference rated power into 4 ohms)
• Frequency response: 10Hz – 100kHz (–3dB)
• Max power: 220 watts
* CEA-2006A-compliant
0 Speaker Output Connectors
• Connect the speakers to these terminals, observing proper polarity.
• Two-channel operation: Connect the left speaker to the L+ and L– terminals and the right speaker to the R+ and R– terminals.
• One-channel (bridged) operation: Connect the single speaker to the R+ and L– terminals.
• Minimum speaker impedance for 2-channel operation is 2 ohms. Minimum speaker impedance for 1-channel (bridged) operation is 4 ohms.
1 Fuses
• Replace only with the same type and rating.
2 Power Input Connectors
• +12V: Connect to the positive terminal of the vehicle’s battery. 10 AWG wire is recommended.
Install an appropriate fuse holder and fuse (30A minimum) within 18 inches of the battery. Make sure the wire is not damaged or pinched during installation. Install protective grommets when routing wires through the firewall or other sheet metal.
• GND: Connect to the vehicle’s chassis. Refer to the picture below.
Factory Bolt Ring Connector
Ground Wire
Note: Remove any paint below ring connector.
Star Washer
• REM: Connect to the “Remote Out” lead from the source unit or to a source of switched
12V+ (ACC).
3 Aux Output Connectors (RCA)
• Nonfiltered pass-through output. Connect to the input of an additional amplifier.
4 Input Connectors (RCA)
• Connect to the RCA outputs from the source unit or signal processor.
5 Input-Level Control
• Used to match the input level of the amplifier to the output level of the source unit.
• See B for the adjustment procedure.
6 Front Crossover-Frequency Control
• 12dB/octave crossover, variable from
32Hz to 320Hz.
• See C for the adjustment procedure.
7 Crossover-Filter Selector
• LPF: Select for subwoofer(s).
• FLAT: Select for full-range speakers when no subwoofer will be used in the system.
• HPF: Select for midrange speakers or full-range speakers when a subwoofer is used in the system.
8 Bass-Boost Control
• Set the Bass-Boost control according to your preference, being careful not to apply enough boost to damage your speaker(s).
9 Power On LED
• Illuminated when the amplifier is on.
A Protect LED
• Illuminated under any of the following fault conditions: battery over/under voltage, short circuit in speaker wires, amplifier is too hot, amplifier’s output circuit has failed (DC voltage is present in the amplifier’s output).
B Setting Input Level
A Turn Input-Level control counterclockwise to
6V (minimum).
B With a dynamic music track playing, turn the head unit’s volume control to the 3/4 position.
C Turn Input-Level control clockwise until the music is so loud that it no longer sounds clear
(distortion is present in the output).
D Turn Input-Level control counterclockwise gradually, just until the music sounds clear, once again.
E Input level is now adjusted correctly.
C Setting the Crossover
A Crossover setting for 5" or larger full-range speakers when no subwoofer is included in the system.
B Crossover setting for midrange and/or full-range speakers when a subwoofer is included in the system.
C Crossover setting for subwoofers.
Note: Acceptable frequency ranges are indicated in gray.

Amplifier Troubleshooting Guide
1. Status LED on Amplifier not Lit - Head Unit (Source) Turned ON
Verify:
A. Remote turn-on wire from source to amplifier has proper voltage
B. Power (B+) connections at amplifier, terminal blocks, and battery are secure
C. Ground (GND) connections at amplifier and vehicle chassis are secure
D. Battery B+ fuse (if used) is OK
E. Amplifier fuse is OK
F. B+ at battery and B+ at amplifier has proper voltage
2. Status LED’s Lit, No Output from Speakers in Normal Operating Condition
Verify:
A. RCA cables from amplifier to source are securely connected
B. Volume adjustment on amplifier is correctly adjusted
C. Source is ON and playing
3. Engine Noise From Speaker(s)
Turn source OFF, Disconnect RCA cables at amplifier. If noise stops, check equipment & cables leading to amplifier.
Verify:
A. RCA cables are of good quality with no breakage to internal shields
B. RCA cables from source to amplifier are not run alongside any power cables
4. Amplifier Output Distorted Music
Verify:
A. Source output music to amplifier is not distorted
B. Source output sensitivity is correctly adjusted
5. Amplifier Shuts Down, Green LED.s are Lit - Amplifier is in Thermal Protection Mode
Verify:
A. Amplifier is mounted with adequate air circulation around heatsinks or vents
B. Amplifier is not mounted under carpet or sealed enclosure
C. Speakers meet correct impedance for application (mono or stereo hookup)
6. Amplifier Does Not Turn ON, and Red LED is Lit Amplifier (and not Connected to a Shorted Speaker)
Verify:
A. Speaker crossover (if used) is not defective
