Speaker Operation
The speakers have an efficiency (SPL) level around 85 dB. This means
that low power amplifiers (25 watts per channel) will give good results.
To adequately reproduce the high dynamic levels of quality recordings
and CD, power audio amplifiers rated up to the power handling
specifications may be necessary.
Precaution
The speakers used in Altec Lansing systems can handle large peaks of
power without damage. This is achieved by special high temperature
wire, adhesive and coil forms. However, damage may occur to the
midrange and tweeter when these speakers are operated from
amplifiers that are highly distorted. Usually some lower power handling
amplifiers are easily driven into “clipping” levels. Even though the
amplifiers are low power, the distorted wave forms can cause damage
more so than the high power clean amplifiers.
In some room locations, speaker performance can be enhanced by
raising the cabinet off the floor. Stabilizers or “feet” in varying heights
are available in high fidelity outlets and raise the cabinet slightly
providing smoother bass response.

We want you listening for a lifetime
Selecting fine audio equipment such as the unit you have just
purchased is only the start of your musical enjoyment. Now it’s time to
consider how to maximize the fun and excitement your equipment
offers. This manufacturer and the Electronic Industries Association’s
Consumer Electronics Group want you to get the most out of your
equipment by playing it at a safe level. One that lets sound come
through loud and clear without annoying blaring or distortion – and,
most importantly without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing “comfort level” adapts
to higher volumes of sound. So what sounds “normal” can actually be
loud and harmful to your hearing. Guard against this by setting your
equipment at a safe level BEFORE your hearing adapts.
To Establish a Safe Level
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and
clearly and without distortion.
• Once You Have Established a Comfortable Sound Level, set the dial
and leave it there.
Taking a minute to do this now will help prevent hearing damage or
loss in the future. After all, we want you listening for a lifetime.
Used wisely, your new sound equipment will provide a lifetime of fun
and enjoyment. Since hearing damage from loud noise is often
undetectable until it is too late, this manufacturer and the Electronic
Industries Association’s Consumer Electronics Group recommend you
avoid prolonged exposure to excessive noise. This list of sound levels is
included for your protection.
