Diagnostics Table - dB Technologies L80D Mode D'emploi

ENGLISH
1 - LIVE
For use during live performances with the speaker placed on a stand. Recommended for musicians
and singers.
2 - PLAYBACK
To listen and use music from MP3 players, CDs, etc.., even in a live situation with the speaker
positioned on a stand. Low and high frequencies are emphasized.
3 - STAGE MONITOR
To be positioned on the floor as stage monitor. Low frequencies, emphasized by the floor, are
limited, thus preventing related feedbacks.
4 - MALE SINGER
Designed for male voices since middle and low frequencies are emphasized minimizing the
feedback due to the proximity effect of the cardioid or hypercardioid microphones.
5 - FEMALE SINGER
Designed for female voices. This preset emphasizes middle and high frequencies, making voices
sharper. The feedback is extremely limited for both cardioid and hypercardioid microphones.
6 - STUDIO MONITOR
Designed specifically for use in the studio, or where a flat response curve of the input signal is
required. In this case the output signal turns out to be as faithful as possible to the original signal.
7 - AUTO LOUDNESS
For all those situations where the music is played in the background. In this case the low
frequencies are extended and enhanced, so as to create a more enveloping sound even at low
sound level.
8 – TALKBACK
Specifically designed to improve speech intelligibility. The frequency response curve in this preset
proves to be appropriate for broadcasting announcements, notices and voice messages.
8 - L160 (Analog)
When the speaker is positioned on a stand, specifically designed for music playback (MP3, CD
etc..). The response curve of the speaker in this preset turns out to be identical to that of the
analogue model L160.

ON for 2/3 sec. Audio MUTED
Initialization of the amplifier module
OFF Audio ACTIVE
Module initialization complete and correct
No signal audio.
OFF Audio ACTIVE
The module has detected a partial anomaly
and remains active with limited functions
Normal operation Audio ACTIVE
The amplifier module reduces the volume, up
to a maximum of 6dBm, as the temperature
rises above the safety threshold.
OFF A momentary lack of supply voltage is
detected during normal operation
Normal operation During normal operation, a current overload is
detected and automatically managed by the
amplifier.
