Thank you for purchasing this Cambridge Audio Topaz SR10 Stereo

Receiver. We are confident that you will enjoy many years of listening

pleasure from it. Like all Cambridge Audio products, the SR10 adheres to

three core principles – stunning performance, ease of use and incredible

value.

Our usual attention to detail is present with a completely discrete high

power bipolar transistor based power amplifier, very quiet speed

controlled fan cooling and a custom low flux toroidal transformer for

audiophile audio performance.

The built-in FM/AM tuner features RDS for station name display on FM

stations that support this function.

The unit can support a wide range of external sources and a front panel

MP3/Portable Media Player input has been fitted which can be used with

the headphone or line-level outputs of most portable players.

The supplied remote control can control this receiver and its built in tuner

plus the matching CD5 or CD10 CD players if required.

Part of our new Topaz range this product also features a new casework

design with braced front panel, rigid wrap-over lid assembly and carefully

designed mechanicals for resonance control.

Your receiver can only be as good as the system it is connected to. Please

do not compromise on the quality of your source equipment, speakers or

cabling. Naturally, we particularly recommend source and speaker models

from the Cambridge Audio range, which have been designed to the same

exacting standards as this product. Your dealer can also supply excellent

quality Cambridge Audio interconnects to ensure your system realises its

full potential.

Thank you for taking the time to read this manual; we recommend you

keep it for future reference.

Limited warranty

Plug Fitting Instructions (UK Only)

The cord supplied with this appliance is factory fitted with a UK mains plug fitted

with a 3 amp fuse inside. If it is necessary to change the fuse, it is important that

a 3 amp one is used. If the plug needs to be changed because it is not suitable for

your socket, or becomes damaged, it should be cut off and an appropriate plug

fitted following the wiring instructions below. The plug must then be disposed of

safely, as insertion into a mains socket is likely to cause an electrical hazard.

Should it be necessary to fit a 3-pin BS mains plug to the power cord the wires

should be fitted as shown in this diagram. The colours of the wires in the mains

lead of this appliance may not correspond with the coloured markings identifying

the terminals in your plug. Connect them as follows:

The wire which is coloured BLUE must be

connected to the terminal which is marked

with the letter ‘N’ or coloured BLACK.

The wire which is coloured BROWN must be

connected to the terminal which is marked

with the letter ‘L’ or coloured RED.

The wire which is coloured GREEN/YELLOW

must be connected to the terminal which is

marked with the letter ‘E’ or coloured GREEN.

If a 13 amp (BS 1363) plug is used, a 3 amp fuse must be fitted, or if any other

type of plug is used a 3 amp fuse must be fitted, either in the plug or adaptor, or

on the distribution board.

Rear panel connections

Audio inputs

These inputs are suitable for any ‘line level’ source equipment such as the

audio outputs of CD players, BD/DVD players, etc.

Phono input

This input has a built in phono stage. Record players fitted with Phono

Cartridges of the Moving Magnet (MM) or high output Moving Coil (MC)

type (between 2-6mV output and 30-50k load impedance) can be used.

Low output Moving Coil types (<1mV and usually 10-1000 ohm load

impedance) cannot be directly connected and will require a matching

transformer or head amp. Please consult your dealer for details. The

‘ground’ terminals on both the record player and the SR10 should be

connected (where possible) with a ground wire for lowest noise/hum

pickup.

Rec Out

Connect to the recording input of a tape deck, CD recorder input, etc.

AM/FM antenna

Tuner aerial connections for picking up radio signals. Refer to the

‘Connections’ section of this manual. For permanent use, outdoor AM/FM

aerials are highly recommended.

Service port

For servicing use only. Do not connect anything here as it may result in

damage.

Loudspeaker terminals

Two sets of loudspeaker terminals are available, A(main loudspeaker

terminals, top row) and B(secondary switchable loudspeaker terminals,

bottom row). Connect the wires from your left channel loudspeaker to the

Left positive and negative terminals, and the wires from the right channel

loudspeaker to the Right positive and negative terminals.

In each case, the red terminal is the positive output and the black

terminal is the negative output.

Care should be taken to ensure no stray strands of wire are shorting

speaker outputs together. Please ensure that the loudspeaker terminals

have been tightened adequately to provide a good electrical connection.

It is possible for the sound quality to be affected if the screw terminals are

loose.

The use of A and B speakers affords you an easy and inexpensive way to

create a simple multi-room system.

Note: When using two pairs of speakers, use speakers with a nominal

impedance of 8 ohms.

Voltage select switch

For servicing use only.

AC power socket

Once all connections are complete, plug the AC power cable into an

appropriate mains socket and turn the unit on.

Aerials

Note: The SR10 is supplied with a temporary aerial for initial use. For

permanent use, outdoor aerials are highly recommended.

AM loop aerial

Connect each end of the single length antenna to the antenna terminals.

Place the antenna as far from the main system as possible to prevent

unwanted noise and to obtain optimum reception. If the AM loop aerial

provided does not provide sufficient reception, it may be necessary to use

an outdoor AM aerial.

Basic connection

The diagram below shows the basic connection of your unit to a

CD player and a turntable and a pair of loudspeakers.

8

Connections

Loudspeakers

Check the impedance of your speakers. When using a pair of speakers,

you can use types with an impedance of between 4 and 8 Ohms. When

using two pairs of speakers, you must use types with an impedance of 8

Ohms each, see later section.

The red coloured speaker terminals are positive (+) and the black speaker

terminals are negative (-). Make sure correct polarity is maintained at

each speaker connector or the sound can become weak and “phasey”

with little bass.

Using bare wire connections

Prepare the speaker cords for connection by stripping off approximately

10mm (3/8”) or less of the outer insulation. More than 10mm could

cause a short circuit. Twist the wires tightly together so there are no loose

ends. Unscrew the speaker terminal, insert the speaker cable, tighten

the terminal and secure the cable.

two sets of speakers to be toggled on and off. Refer to the Front Panel or

Remote Control section of this manual for more information on the

Speaker A/B operation.

Bi-wire connections

If your loudspeakers are equipped with two sets of terminals, then it is

possible to connect them in the bi-wire configuration. Bi-wiring sends the

bass and treble frequencies down separate speaker cables, resulting in

a clearer, more focussed sound.

Note:

– Speaker A and B must both be selected for this type of connection to

work.

– Remove the bi-wire link on the speaker terminals before connecting.

Refer to your speakers’ manual for more information.

Ensure the plug is fully inserted into the wall socket and is switched on.

Check fuse in the mains plug or adaptor.

Check the power is on at the front of the unit.

There is no sound

Check the correct input is selected.

Check that the speakers are connected correctly.

If using the tuner, check aerial connections and an available station is

selected.

Check the unit is not in mute mode.

Check the Speaker A/B configuration matches your speakers.

The sound is distorted

Check aerial connections and placements.

Check speaker connections.

There is a hum coming from the speaker

Ensure that all cable connections are secure, particularly ground/shield

connections. For turntables.

There is unwanted background noise and interference

Move the unit away from other electrical equipment that is likely to cause

interference.

Re-orientate the aerial.

Ensure that all cable connections are secure, particularly ground/shield

connections for turntables.

The remote handset will not function

Check that the batteries have not expired.

Ensure that nothing is blocking the remote sensor.

Over temperature protection

The unit has an over temperature and shutdown protection. If the unit is

continuously used for a long period and over heats, the unit will shut

down. Leave the unit ‘ON’ for 10 minutes to cool down, then turn the unit

off and on to continue listening.

If the problem persists, then the unit is being over driven. Reduce the

volume level, and ensure the unit is in an open ventilated area to resolve

the problem.

Use of two pairs of speakers which are less than 8 Ohms can cause

overloading and is not recommended.
