Angstrom ALFT10S-150 Ambienti Quick Start Manual

Thank you for purchasing this Low Frequency Transducer (sub-woofer). We hope that you derive many years of listening pleasure from it.
This model is one of a range of Low Frequency Transducers designed and built to provide trouble free performance and can reproduce
powerful and controlled low frequency information to supplement the performance of any domestic audio system.
The lightning flash with arrowhead,

to alert the user of the presence of
un-insulated "dangerous voltage" within the
product's enclosure; that may be sufficient
magnitude to constitute a risk of electric
shock to persons
This unit has been supplied with an approved AC power cable with a molded plug. Always replace fuse with the same type only.
There are no user-serviceable parts. Please refer to a qualified service engineer.

Human hearing is not sensitive to the exact origin of low frequency information so the placement of the Low Frequency Transducer is not so critical.
It's advanced design disperses the sound evenly throughout the listening area. Locating the Low Frequency Transducer near a wall will increase the
bass response of the loudspeaker, however, the sound waves coming from Low Frequency Transducer are long and need space to propagate. If
placed too close the listener, the sound will not be as full as if it was a little further away. The adjustments possible on the unit will allow it's performance
To be modified to suit the particular circumstances of your listening environment. The output level is best set when listening to all of the loudspeakers.
It cannot easily be set in isolation. Keep the Low Frequency Transducer away from radiators or other heat sources and at least 50cm from television.
The Low Frequency Transducer may be connected to your system in several different ways depending on what other types of loudspeakers you are using
what output options offered by your amplifier.
These RCA Phono Sockets can accept the variable line output from a pre-amp, receiver or a surround sound decoder being controlled by a pre-amp or
receiver. They should not be connected to a tape recorder output as that signal is generally of fixed level and can not be adjusted by the volume control
of the amplifier from which it comes. Some units feature a signal variable Low Level Transducer output which should be connected to Low Frequency

These inputs are designed to accept an amplified signal from the loudspeaker outputs of an integrated amplifier
Note: Ensure that you never use the Low Frequency Transducer with connections made to the LINE IN and HI LEVEL IN terminals simultaneously.
The original amplified signal connected the HI Level inputs is present at these outputs minus the frequencies being used the Low Frequency Transducer.
These may be connected to the existing left and right loudspeakers. If your main loudspeakers are small, the overall power handling of the system will be
significantly increased if they are connected not to the outputs of your integrated amplifier, receiver or power amplifier but to the Hi Level outputs of the
Low Frequency Transducer. These outputs filter out low frequency information being handled by the Low Frequency Transducer sending only the upper
bass, mid0range and high frequency signals to the main loudspeakers which makes their task easier and which allows for higher sound pressure levels
to be achieved. This will enhance the impact of high quality music and audio-visual source material.
