Section 2: Introduction Congratulations on your purchase of JBL Professional 3 Series Studio Monitors. The 3 Series meet JBL’s high standards for accuracy and long-term reliability in demanding professional applications. All 3 Series models incorporate JBL Professional transducer and network technologies to provide accurate frequency response, exceptional low frequency extension and high SPL capability.
LSR310S POWERED STUDIO SUBWOOFER FEATURES Producing extended low frequency response into the 20Hz region, the LSR310S is the perfect match for the 3 Series MkII studio monitors. The LSR310S feature set includes: • A Magnetically-shielded low frequency transducer, equipped with a 1.5" voice coil and robust motor structure for excellent low frequency performance. By reducing thermal-related effects, the 3 Series MkII Studio Monitors and LSR310S Subwoofer sound the same at low, medium, and high levels.
Section 3: Setting Up Your System EACH 3 SERIES CARTON INCLUDES THE FOLLOWING ITEMS: • One 3 Series MkII studio monitor or 3 Series subwoofer • One power cord • Quick setup guide • Four peel-off rubber pads (305P, 306P, and 308P MkII models only) UNPACKING When removing a speaker from its packaging, we recommend the following procedure, which will prevent damage of the high frequency transducer: 305P, 306P, and 308P MkII models: 1. Remove the outer shipping carton, if one exists. 2.
• Ideally, 3 Series MkII Studio Monitors should be placed on suitable speaker stands, rather than on the work surface. This will reduce resonance and deterioration of low frequency performance caused by the speaker’s mechanical coupling with the work surface. • For optimum imaging, the left and right speakers should be placed symmetrically in the room, so each speaker is the same distance from adjacent walls and reflective surfaces.
AUDIO CONNECTIONS NOTE: Before making audio connections, ensure the VOLUME control on each 3 Series speaker/subwoofer is set to the full counter-clockwise (minimum) position. The 3 Series speakers are equipped with balanced XLR and 6mm (¼") TRS inputs for connection to professional computer audio interfaces, mixing consoles, and audio production equipment, as well as unbalanced consumer audio products such as personal music players, consumer audio receivers, and audio visual equipment.

HIGH FREQUENCY TRANSDUCER (TWEETER) – This transducer reproduces high frequency signals. 2. WAVEGUIDE – The specially designed JBL Image Control Waveguide enhances imaging and optimizes the blend of direct and reflected sound in the room, ensuring neutral sound at the mix position. 3. POWER LED – This LED illuminates when power is connected and the POWER switch is set to ON.
INPUT PANEL 9. XLR INPUT – Connect professional equipment to this connector using a balanced XLR plug. 10. 6MM (¼") INPUT – Connect professional equipment to this connector using a 6mm (¼") balanced plug. Connect consumer equipment to this connector using a 6mm (¼") unbalanced plug. 11. INPUT SENSITIVITY SWITCH – Set this switch to +4dBu to protect from overload when connecting to professional equipment and sources with high output level capabilities.
AUTO STANDBY FEATURE 3 Series MkII models bearing the CE mark include an automatic low-power standby feature that reduces power consumption when no signal is detected for a period of twenty minutes. When used in professional applications in which auto-low power standby is not desirable, the feature can be disabled. The feature is enabled by default. Use the following procedure to disable the auto-low power standby mode: 1. Power speaker OFF. 2. Set BOUNDARY EQ to the “0dB” setting. 3.

INPUT PANEL 6. RIGHT AND LEFT XLR INPUTS – Connect professional equipment to these connectors using balanced XLR plugs. 7. RIGHT AND LEFT 6MM (¼") – Connect professional equipment to these connectors using 6mm (¼") balanced plugs. Connect consumer equipment to these connectors using 6mm (¼") unbalanced plugs. 8. RIGHT AND LEFT XLR OUTPUTS – Connect these outputs to the 3 Series MkII speakers or other powered speakers or power amplifier in your monitoring system. 9.
AUDIO CONNECTIONS Connect signal sources to either the XLR or 6mm (¼") INPUT connectors. Connect a single signal source to the speaker using either the XLR INPUT connectors, OR the 6mm (¼") TRS INPUT connectors. Do not connect multiple signal sources to the XLR and 6mm (¼") input connectors simultaneously. If the LSR310S subwoofer is being used to reproduce the .1 LFE channel in a surround sound system, connect the .1 LFE signal to either the LEFT or RIGHT input of the subwoofer.
CROSSOVER SETTINGS AND BASS MANAGEMENT “Bass management” is a term that refers to the practice of using a subwoofer to reproduce the bass frequencies of the main channels. Because of the physiology of the human ear, low frequencies are largely non-directional. Given an adequate listening distance, we can’t easily tell where bass signals are coming from.

Section 7: Troubleshooting Issue: There is no sound from the speakers. • Confirm the power cable is connected to the speaker and the POWER switch is set to the ON position. • Make sure the POWER LED is illuminated on the front of the speaker. • Make sure a signal source is connected to the speaker and that it is producing sound. • Make sure the speaker's VOLUME control is not set to the full counter-clockwise (minimum) position. Issue: The signal is distorted.
