Audio

Speaker Drivers

The SBC 2 speaker bar features dual 4″ LF drivers paired with a pair of 1″ soft dome HF drivers. Each driver is driven with 20 WRMS power to provide a frequency response 50 Hz – 20 kHz +/- 3 dB at a maximum SPL 106 dBA.

Audio Mode selection

The Mode selection switch selects between RS-232 control mode and the Auto on/off mode. The position of the Mode switch in the Auto on/off positions selects one of three EQ presets. EQ presets can also be selected in RS-232 mode using commands. The presets are Video Conference, Music, and Present (presentations).

Auto on/off mode

When the switch is placed in any of the Auto on/off mode’s three EQ positions, the conferencing bar activates its automated Wake-on-signal function. This sets the bar to automatically power on and off in response to sensed signals on its ports. Setting the switch in Auto on/off mode activates the Wake-on-signal even if it was previously disabled by a command in RS-232 mode.

In Auto, on/off mode, the RS-232 control port is still active. However, the SBC 2 bar will not respond to incoming commands or queries except to signal the connected control system that the conferencing bar is set to Auto on/off.

RS-232 mode

In RS-232 mode, the active RS-232 port is used to control the bar with commands, and status can be requested through queries.

The Wake-on-signal function is disabled by default in RS-232 mode. However, the function can be activated by RS-232 command if both Wake-on-signal and RS-232 control are needed for the application.

Note: RS-232 control is deactivated when the bar is set to Auto on/off mode.

Equalizer presets

The EQ presets provide enhanced listening experiences for three use scenarios.

Equalizer 1: Music. This setting is optimized for the best overall experience when listening to various types of music.
Equalizer 2: Video Conference setting. This is the default setting when the Bar is operating in RS232 mode, and it enhances the experience when using unified communication equipment with the Sound Bar.
Equalizer 3: Present setting (presentations). Optimized for Presentations with a combination of videos and speech.
Reminder: The presets can be selected using RS-232 commands or by using the Mode switch on the back of the bar.

Source behavior

Analog signals: Balanced and RCA
When powered on via the activating analog input sources (Balanced or RCA), the bar remains in the on state while a signal is present. When the signal is removed, the bar stays on for 20 minutes before automatically powering off. After powering off, the Wake-on-signal function re-activates, sensing for an active signal.

Digital signals: HDMI-ARC and USB Audio

When connecting using the HDMI or USB ports, the bar uses the first digital signal detected to designate its active source. The bar will look for another active source when the first signal is lost. In the absence of a signal, the bar will stay on for 20 minutes before powering off.

In the adjacent example illustration, the connected TV is turned on first, making the HDMI-ARC port the active source for the bar. The user then decides to change the source to USB Audio and looks for the sound bar as a source on his Laptop audio output. However, the bar will not show up as a source on the laptop until the TV is switched off, causing the USB source to register as the new active source.

Likewise, if the USB source was activated first, the TV will not detect the Sound Bar on HDMI-ARC until the USB is disconnected from the Laptop.

When connecting the SBC 2 to a PC, the enumerated audio output shows as “Parlé SBC 2”.

Note: The USB is version 2.0, The USB cable length should not exceed 5 meters (15 feet).
