All of our in-wall/in-ceiling speakers are designed to be used in a wall without the need for a back-box. The specs provided are based on no back-box. However, when adding a back-box (really only possible when doing new construction), you will improve the low frequency response a bit, getting a tighter bass response.

It is a model made for vocal use.

BDS 280S and 580S support 802.11b, g and n. (2.4GHz ISM Band, Europe 13 Channels).

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 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.

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.

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.

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).

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.

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.

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.
