Circuit Diagram (Schematic)

If the SB 15/230 is manually put into Standby on the ON/OFF Button on the SB 15 unit itself, it can only be switched back ON by manually pressing the ON/OFF button again.

Auto Turn on

The SB 15/230 automatically enters Standby‐mode after approx. 15 minutes if no audio signal is detected.  This can also be forced by learning (for example) the TV set’s remote control “Off” code into the SB 15/230.

Due to Power saving regulations, the SB 15 does not “listen” to the Audio Inputs, unless it senses a remote signal first, which can be any kind of remote signal (it does not have to be a learned remote code ‐ turning ON the TV or sending any other infrared remote code will be enough). The remote signal will tell the SB 15/230 to start up automatically as soon as audio is detected on (first) the Digital or (second) the Analog audio Input. If no signal is detected by the Inputs, the SB 15 will go back into total Standby again after approx 15 minutes. Problems

There is no sound coming from both the soundbar and the subwoofer

> Check that the soundbar is on (the Power Indicator is illuminated blue)
> Check that the cable connecting the TV or other source component to the soundbar is properly connected at both ends
> Check that the soundbar’s Source Selector is set to the correct source (the Source Indicator illuminates white for Source 1 – analog, and illuminates blue for Source 2 – digital), and that the source is playing an audio signal > Check that the system is not muted (when the system is muted, the soundbar’s.  Power Indicator flashes blue) Momentarily press the Power button to un-mute the system.
> Check that the soundbar’s volume is not turned all the way down (the lowest setting of the Volume Down button will mute the system).

There is no sound coming from just the subwoofer
> Check that the Subwoofer Volume Control is not turned all the way down (fully counterclockwise)
> Check that the Wireless Code switches on the subwoofer and soundbar are both set to the same setting number • Move the subwoofer closer to the soundbar (The maximum wireless operation distance is 50 feet (15 3m).

Soundbar’s sound is distorted
• Set the soundbar’s Trim switch to a lower setting
• Check the source component to see if the distortion is coming from it, and not the soundbar.

The system’s sound is too quiet, even when the soundbar’s volume is turned all the way up
> Set the soundbar’s Trim switch to a higher setting
> If the TV or source component is connected via a variable output, check its instructions to be sure that the output is not turned down too low.

The bass output is not loud enough
> Turn up the subwoofer’s Volume knob
> Move the subwoofer into a corner of the room
> Move the subwoofer closer to the seating location.

If you press your TV remote’s Power button and the soundbar turns off when the TV turns on (or vice versa)
> Press the Power button on either the soundbar or the TV (but not both) one time This will put them back in sync so they will turn on and off together when you press the TV remote’s Power button. The subwoofer does not turn on

> Check that the subwoofer’s power cord is plugged into a working AC outlet
> Check that the subwoofer’s Power switch is in the On position
> Check if the subwoofer’s AC fuse has blown.
