How To

General Answer: The volume control circuits in the No.585 have been designed to provide exceptionally high levels of accuracy and linearity, and have been tuned to provide the best possible listening experience. You may hear small clicking sounds when quickly adjusting the volume control during periods of silence – this is normal when there is no input signal. The sounds are greatly diminished under normal use when listening to active audio sources. Detailed technical explanation: The volume control in the №585 is built around a circuit architecture called an R-2R ladder, a highly accurate device. The R-2R ladder in the №585 is based on an R of 1000 ohms, which is smaller by a factor of 10-100 than most potentiometer-based volume controls. The result is a nearly constant bandwidth, from the lowest volume setting to the highest, of greater than 400 kHz, more than an order of magnitude above the upper limit of human hearing. Because the resistance value in the R-2R ladder is so small, and because all DC blocking capacitors have been eliminated from the signal path of the №585, the few micro volts present on the input and output stages can give rise to extremely small but measurable DC currents flowing in the R-2R ladder. When the user adjusts the volume setting, the miniscule changes in DC current flowing from the ladder into the output stage occasionally can be perceived as small clicks, typically audible only under extremely quiet listening conditions.

Since the No. 40 uses a card cage design, all of the No. 40 boards plug into a backplane. Since the No. 40s Video Processors backplane was designed before HDMI existed it cannot accommodate HDMI video, so the HDMI video signal is passed straight through from one of the three HDMI inputs on the HDMI card to the system’s display device via the HDMI output. Plugging the No. 40 HDMI card into the Audio Processor allows us to capture the HDMI audio signal and process it.

We do not publish a frequency response for these models because this is dependent on room acoustics and their internal DSP settings.

This can be caused by the “input switch” on the unit’s rear panel not being fully engaged in the proper position; make sure that the “input switch” is fully engaged in the proper position (RCA or XLR). Also, make sure that only one input connector is used at a time, i.e., only the RCA or the XLR. They should not be used simultaneously. Explanation: The “input switch” is actually a ground switch, not an input selection switch. By using the switch only to change the ground connection, the signal connections never have to pass through a set of switch contacts. This allows for superior audio performance and enhanced long-term reliability.

If the preset DAB/FM station signal is not strong enough the alarm will go off in buzzer mode instead. Make sure the signal is strong enough, by checking that the station plays without static or distortion (FM).

We believe the baseline performance of the QuantumSPHERE technology is cutting edge in terms of localization. The calibration feature improves upon this performance by calibrating the system to your individual anatomy.

There is a setting in the JBL One app called Bluetooth reconnection. You can change the behavior to enable it to automatically reconnect every time the speaker is turned on, if this is the behavior you want.

The speaker has an auto calibration feature, which measures the space around the speaker and adjusts the sound quality based on the room around it. Auto calibration will automatically work when you power on the speaker and begin playing music. For the best sound, we recommend placing the speaker in the middle of the room, at least 0.5 meters away from any walls.

When not connected to AC power, the speaker will be automatically switch off after 1 hour of inactivity to save battery consumption. You can adjust the auto standby time on JBL One app.

Due to compatibility issue, clear the Harman Kardon One app cache and try to update it again.

You need to charge your Onyx Studio 9 using the power cord included in the package. It takes about 4 hours to fully charge.

This is by design to achieve maximum battery play time. To get Maximum loudness connect the unit to AC power during usage.

The remote is only capable of operating one device at a time (unless you have programmed advanced functions such as Volume, Channel or Transport control Punch-Through). When you press the Source Selector to operate your other product, such as the DVD player, the remote cannot control any other product, including the AVR, until you press the AVR Button again. To avoid your problem in the future, always press the AVR Button or appropriate Source Selector before you enter any command.

If your Micro II does not sense an audio signal on its input, it goes into Standby to save power. It should wake up again when audio is sensed. Since Micro II senses audio on its input, not on the speaker volume, always turn up the volume on the source, then control speaker volume on the Micro II. This way it will not go into Standby unless music stops.

An unstable internet or connectivity might cause software updates to fail during the Stereo Boost Pairing mode.

Press and hold the "Bluetooth" button to quit the Stereo Boost Pairing mode, and update the speaker independently.

Please check your OS version. If you are using an iPhone with OS version of 8.3 or lower , please upgrade your system to the latest version.

To ensure the best sound experience, the battery performance of the Onyx Studio 9 is adjusted under the following conditions:

1. The speaker is in battery mode and the battery level is below 30%.

2. The music volume is at or above 50%.

To charge your device, try plugging in the AC cable or lowering the music volume.

The “Speaker” mode allows the JBL QuantumENGINE to receive more than two channels of audio. It also prevents some applications from adding extra signal processing intended for other headphones, which would negatively impact the performance of the JBL QuantumSURROUND or JBL QuantumSPHERE 360 technology.

If you are unable to get test noise output per channel from the SDP75, the Clock Source is likely set to "External". Changing the Clock Source to "Internal" should prove to fix the issue.
