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.

General Answer: When an input is set to SSP mode the No.585 acts as a simple amplifier. In other words, the volume control in the No. 585 is disabled and the gain of its preamp is set to 1, so the No. 585 functions as if the signal source were connected directly to its power amplifier channels. However, under typical listening conditions, a preamp is almost always operated with a gain of significantly less than 1. In fact, for the preamp in the No. 585 to operate at a gain of 1 requires its volume to be set between 66 and 67, which is likely much higher than anyone sets their volume control for ordinary listening. This high effective volume setting in the No. 585 is necessary so that the volume control in the connected AVR/AVP can be used effectively. But if that AVR/AVP is noisy, or if the audio system is set up in an area susceptible to electromagnetic noise, the noise will be reproduced through the No.585. This will be most evident when there is no audio playing through the system but is usually imperceptible when audio is present. In the SSP mode the No.585 system does not introduce noise, but simply amplifies whatever is present on that input. For the best performance care must be taken with the volume level of the source, and it is recommended to always use the balanced inputs (XLR connectors - see owner’s manual for details) for any inputs you plan to set to SSP mode. Technical Explanation: In the past, the differing number of channels in each component made integration between two-channel and multichannel components difficult. Sending multichannel processor output signals to a stereo Preamplifier distorts calibrated processor output levels. Multichannel processor volume controls adjust the relative volume level of all channels in unison. However, stereo Preamplifier volume controls adjust the relative volume level of just the front left and right channels, leaving the center, surround, and subwoofer channels unaffected. To avoid these problems when the No.585 is connected with an associated surround-sound processor, the SSP mode allows selected input sources to pass through the No.585 without interference. When SSP mode is activated the No.585 volume control is deactivated to prevent the No.585 from distorting channel balance. As a result, the processor controls the relative volume level of all channels while maintaining its calibrated output levels. To connect the No.585 with a surround-sound processor (see illustration in owner’s manual): 1. Make sure the No.585 and all associated components are powered off and disconnected from electrical outlets. 2. Connect the output connectors on the surround-sound source component to the input connectors on the surround-sound processor. For example, if the source component is a Blu-ray disc player, connect it to the appropriate input connectors on the surround-sound processor. 3. Connect the front left and right output connectors on the processor to the desired input connectors on the No.585. For best performance, use balanced connections whenever possible. 4. Connect the center, surround, and subwoofer output connectors on the processor to the appropriate input connectors on the power amplifier(s). 5. Connect the No.585’s speaker outputs to the system’s front left and right (main) speakers. To activate the SSP mode for a selected input: CAUTION: Before activating the SSP mode for any input, set the associated surround sound processor volume control to a reasonable level to prevent sending dangerous signal levels to the associated loudspeakers. 1. Activate the Setup menu by pressing the Setup button. 2. Select Input Setup, and press Enter. 3. Select the input you wish to configure for SSP use, and press Enter. 4. Select SSP, and press Enter. 5. Set the SSP parameter to On. 6. Press the Setup button four times to step backward through the menu hierarchy and exit the Setup menu.

To minimize e-waste, we consciously choose not to include a charging cable in our packaging.

You can use any standard USB-C cable to charge your JBL product as well as a power adapter compliant with the USB-C standard.

Past product already have standardized USB-C cables, which can be reused for new products.

To minimize e-waster, we consciously choose not to include a USB-C PD Adaptor in our speaker packaging.

You can purchase the dedicated 15-60W JBL USB-C PD adaptor on jbl.com or any other retail stores. Simply connect the USB-C PD Adaptor with your speaker and enjoy the guaranteed performance JBL promised.

In the ANC on mode, we take advantage of advanced signal processing to finely tune, and personalize the audio performance. In passive and in ANC off mode, that signal processing is not running, so you may hear a difference in audio performance

This speaker will go to standby mode after 10 minutes inactivity. It turn on when you start playing to it again.

Only if you have pressed the button on the remote or Boost TV itself.

It will not upmix 7.1 as powered by the proprietary algorithm for the advanced surround sound. JBL uses binaural synthesis to use 1 virtual source per channel which leads to better precision.

Yes, they will work together. You can link rooms containing 1st generation Omni speakers with rooms containing 2nd generation Omni speakers and listen to the same music across all of them. Since the 2nd generation has a more powerful processor, we recommend connecting external sources like AUX or Bluetooth to the 2nd generation speakers rather than the 1st generation.

Yes, when casting music to your JBL Playlist, your speaker is connected to Google Cloud, which will turn your smart device into a remote control, rather than streaming music directly to the Playlist. You can easily do other things with your phone while using Chromecast, such as gaming, texting, make calls, watch Youtube etc. This will not interrupt the music that you are casting.

Yes, after 10 minutes of no audio activity, the soundbar will enter standby-mode automatically. Or you can do it yourself by short pressing the Power button.

Yes. Just connect an Adapt to your existing Hi-Fi equipment or active speaker via the 3.5mm line out port to transform any speaker into a wireless speaker in the Harman Kardon Wireless HD Audio System
