Introduction

Last updated: January 19, 2023 02:00. Revision #8446

Thank you for purchasing these Cambridge Audio Incognito outdoor speakers. We hope that you enjoy many years of listening pleasure from them.

Your speakers 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 speakers. 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.

What's included with the ES20?

Last updated: January 19, 2023 02:35. Revision #8447

1. 1 x ES20 Outdoor Speaker

2. 1 x Mounting Bracket.

Installation instructions

Last updated: January 19, 2023 02:35. Revision #8448

Before installing your ES20 outdoor speakers, consider their positioning and requirements for cabling. Where possible use existing cover to minimise

direct exposure to the elements and ensure that the wall being used for mounting will be able to support the weight of the speaker.

1. Firstly, mount the mounting bracket horizontally or vertically in your desired location, then feed your speaker cable through the bracket prior to

connection.

2. With your ampliﬁer turned oﬀ, connect the speaker using the terminals located on the rear panel. Please ensure that you match the polarity of

each connection between speaker and ampliﬁer.

3. Loosely ﬁt the speaker to the mounting bracket and adjust it to your desired position. We would recommend angling the speaker downwards

slightly to minimise direct exposure to the elements. Once you’re happy with the positioning, tighten the two knobs to secure the speaker.

Frequently asked questions

Last updated: January 19, 2023 02:35. Revision #8450

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

Last updated: January 19, 2023 02:35. Revision #8451

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 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.
