Product Usage Instructions
Front Panel
The front panel of the EVO S Bookshelf Speakers features a 25mm Silk Dome
Tweeter and a 6.5(165mm) Anodized Aluminium Mid/Bass Driver.
Rear Panel
The rear panel of the EVO S Bookshelf Speakers features a rearbass port and
+/- Speaker connection terminals.
Installation Instructions
- Using high-quality speaker cable, connect the EVO S speakers to the speaker terminals on your amplifier. Ensure that you pay close attention to match the polarity of each connection.
- If placed on a desk or close to a wall, you may benefit from using the included foam bass tuning bungs. These can be placed into the rear port of each speaker to reduce the low-frequency output.
- When positioning, we would suggest that the distance between speakers and the listening position is equal. However, we would encourage experimentation until you find a solution that works for your space.

Frequently Asked Questions
What is meant by speaker sensitivity?
Speaker sensitivity refers to how loud a speaker can get with a given amount
of power. The higher the sensitivity rating, the louder the speaker will be at
a given power level.
What is a crossover?
A crossover is a component in a speaker that separates the audio signal into
different frequency ranges and sends each range to the appropriate driver
(e.g., tweeter, midrange, woofer).
What is impedance?
Impedance is the measure of resistance that a speaker has to the flow of
electrical current. It is measured in Ohms () and is an important
consideration when setting up an audio system as it determines the ‘load’
placed on an amplifier by the speakers.
Troubleshooting
There is no troubleshooting information provided in the user manual.

Introduction
- Thank you for purchasing these Cambridge Audio EVO S bookshelf loudspeakers. We hope that you enjoy many years of listening pleasure from them. Your loudspeakers can only be as good as the system it is connected to. Please do not compromise on your amplifier or cabling. Naturally we particularly recommend amplification from the
- Cambridge Audio range, which has been designed to the same exacting standards as our loudspeakers. Your dealer can also supply excellent quality speaker cable to ensure your system realises its full potential.
- Thank you for taking the time to read this manual; we do recommend you keep it for future reference.

Frequently asked questions
Last updated: Styczeń 19, 2023 02:00. Revision #8444
What is meant by speaker sensitivity?
Speaker sensitivity is the level produced by the speaker at one meter, when supplied with one watt of power from an amplifier. It’s a way of describing how well the speaker produces acoustic energy, based on a given input. The level is measured in dB SPL – this shorthand for ‘sound pressure level’ – sound is basically fluctuations in air pressure, so any time you see SPL, this means ‘sound in the real world’. So, let’s say we have a speaker with an 87dB sensitivity, and a speaker with a 90dB sensitivity – the 90dB speaker is going to be considerably louder, as every 3dB added represents a doubling of power.
What is a crossover?
Most speakers will have multiple drivers. A driver is sometimes called a transducer, which is a device that turns one type of energy into another – in this case, electrical energy to sound energy. In a loudspeaker, it is often the case that we might want multiple drivers – one to handle low-end, one to handle the mid-range, and one to handle the treble. This latter driver is often called a tweeter. To get the benefit of this arrangement, we need to split the signal into different frequency components. The circuit that does this is called a crossover.
What is impedance?
You will often see impedance mentioned when researching speakers, and
amplifiers. Impedance is basically resistance measured at a given frequency,
given as a value in Ohms (Ω), and is incredibly important to consider when
setting up an audio system as it determines the ‘load’ placed on an amplifier
by the speakers.
For example, let’s say we have an amplifier that is rated to deliver 100W into
an 8Ω speaker load. If we were to then use speakers with an impedance of 4Ω
with the same amplifier, the amp would then need to supply 200W as a halving of
the impedance results in a doubling of the required power due to the reduction
of the load on the amplifier.
In a situation such as this, if the amp can’t supply the required power for a
lower impedance, then it can result in overheating and damage to the amplifier
and speakers.
For this reason, it is important to pay attention to amplifier specifications,
and suggested impedance ratings.
Troubleshooting
No sound through one or both channels.
- Check that the amplifier is turned on.
- Ensure that the correct input source is selected on the amplifier.
- Confirm that all connections between the amplifier and loudspeakers are secure.
- Check that the connections between the source equipment and amplifier are secure.
- Check the polarity of the loudspeaker connections.
- Check that the volume control is set correctly on the amplifier.
There is a distorted or inconsistent sound.
- Confirm that all connections between the amplifier and loudspeakers are secure.
- Check the polarity of the loudspeaker connections.
- Check that the connections between the source equipment and amplifier are secure.
