Nastavení

1. Umístění

Position the LSR305 monitors to form an equilateral triangle with your listening position. The monitors should be angled inward, pointing towards your ears, to optimize the stereo image and take advantage of the broad sweet spot provided by the Image Control Waveguide. Avoid placing the monitors directly against a wall if possible, as the rear-firing Slip Stream™ port can affect bass response. Maintain some distance from walls for optimal low-frequency performance.

2. Připojení

The LSR305 offers balanced XLR and 1/4-inch TRS inputs for professional signal quality. Connect your audio interface, mixer, or other audio source to the appropriate input on the rear panel of each monitor. Ensure secure connections for optimal performance.

3. Připojení napájení

Connect the provided power cord to the AC inlet on the rear of the monitor and then to a suitable power outlet. Ensure the power switch is in the 'OFF' position before connecting to power.

Operace

1. Zapnutí/vypnutí

Locate the power switch on the rear panel of each monitor. Flip the switch to the 'ON' position to power on the monitor. It is recommended to power on your monitors last and power them off first to prevent any sudden pops or surges.

2. Ovládání hlasitosti

Adjust the volume knob on the rear panel to set the desired listening level. Start with a low volume and gradually increase it to a comfortable level. For critical listening and mixing, ensure both monitors are set to the same volume level.

3. LF and HF Trim Controls

The LSR305 features LF (Low Frequency) and HF (High Frequency) Trim switches. These allow you to adjust the bass and treble response to compensate for room acoustics or personal preference. Experiment with these settings to achieve the most accurate and balanced sound in your specific environment. Typically, a flat (0dB) setting is a good starting point.

4. Input Sensitivity Switch

The input sensitivity switch allows you to select between +4dBu (professional) and -10dBV (consumer) input levels. Use the +4dBu setting when connecting to high-output professional gear to prevent input overload and maintain signal integrity. Use the -10dBV setting for consumer-level audio equipment.

Údržba

To ensure the longevity and optimal performance of your JBL LSR305 monitors, follow these maintenance guidelines:

• Čištění: Regularly wipe the exterior surfaces with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish.
• Prach: Keep the speaker cones and ports free of dust and debris. A soft brush or compressed air can be used carefully.
• Prostředí: Monitory používejte ve stabilním prostředí, mimo dosah extrémních teplot, vlhkosti a přímého slunečního záření. Zajistěte dostatečné větrání kolem zadního panelu, abyste zabránili přehřátí.
• Zacházení: Handle the monitors with care. Avoid touching the speaker cones directly, as this can cause damage.

Odstraňování problémů

• Žádný zvuk: Check all power connections and ensure the monitors are switched on. Verify that the audio source is active and connected correctly to the monitor inputs. Check the volume knob position.
• Hučení nebo syčení: Ensure all audio cables are balanced (XLR or TRS) and properly connected. Unbalanced cables can introduce noise. Check for ground loops or interference from other electronic devices. Adjust the input sensitivity switch if the input signal is too high or too low.
• Zkreslený zvuk: Reduce the input volume from your audio source or the monitor's volume knob. Ensure the input sensitivity switch is set correctly for your equipment. Check for damaged cables.
• Nerovnoměrný zvuk: Verify that both monitors are placed symmetrically and angled correctly towards your listening position. Ensure LF and HF trim settings are identical on both monitors.
