1. DIGITAL INPUTS (AXR100 ONLY) – TOSLINK and S/P DIF co-axial digital inputs.
   Note: To obtain the best results from your system we recommend using only high-quality Cambridge Audio interconnects. This will ensure that you hear your system as we designed it. Please ask your dealer for details.

2. AUDIO INPUTS – These inputs are suitable for any ‘line level’ source equipment, such as the audio outputs of CD players, BD/DVD players, etc.

3. 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 Ohm 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 Phono pre-amp.
   Note: The ‘ground’ terminals on both the record player and the AXR should be connected (where possible) with a ground wire for the lowest noise/hum pickup.
   Due to stray magnetic fields, turntables should not be located nearby due to possible interference.

4. REC OUT – Connect to the recording input of a CD recorder input, tape deck, or other compatible recording device, etc.
   This output provides a constant high-level output that does not fluctuate with the volume of the main unit. For this reason, the AXR85/100 cannot be used as a Preamplifier only and the Rec Out can’t be connected to a Subwoofer.

5. SUB OUT – Connection to the input socket of an active subwoofer.
   Note: There is a 2nd order low pass filter of 200Hz applied to the Sub Out, which will filter out frequencies above 200Hz.
   The frequency of the connected speakers is not adjusted when the Sub Out is in use, they will still be sent the full frequency range.

6. 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.

7. SERVICE PORT – For servicing use only. Do not connect anything here as it may result in damage to the unit.

8. BLUETOOTH ANTENNA – Used for wireless streaming Bluetooth (A2DP/AVRCP) audio capability directly from most phones, tablets, and laptops. Refer to the ‘Operating Instructions’ section of this manual.

9. LOUDSPEAKER TERMINALS
   Note: When using a banana plug, make sure the speaker terminals are completely tightened before inserting the plug.
   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. The sound quality can 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: The speaker terminals will need to have the round pips removed before you can insert a banana plug into them.
     Note: When using two pairs of speakers, use speakers with a nominal impedance of 8 Ohms.

10. HEAT TUNNEL VENT GRILLE – Allows cooling of internal circuitry via the heat tunnel. DO NOT OBSTRUCT.

11. VOLTAGE SELECT SWITCH – For servicing use only.

12. AC POWER SOCKET – Once all connections are complete, plug the AC power cable into an appropriate mains socket and turn the unit on.

Please only use the power lead supplied with the unit.

Getting Connected

Last updated: December 15, 2022 04:04. Revision #9839
LOUDSPEAKERS
Check the impedance of your speakers. You can use speakers with an impedance of 4 – 8 Ohms.
The red-colored speaker terminals are positive (+) and the black speaker terminals are negative (-). Make sure the correct polarity is maintained at each speaker connector or the sound can become weak and “phase” 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.
Note: All connections are made using standard loudspeaker cable.

USING BANANA PLUGS
We recommend using Banana plugs with our units to establish a secure connection and ensure there are no loose strands of wire that may cause unwanted noise or interference.
Once you have stripped the outer insulation of the cable and twisted the wires as indicated below, securely connect these to your banana plugs, remove the dust cap from the end of the speaker terminal and push the plug in as far as possible without applying excessive force.

Notes

• When using a banana plug, make sure the speaker terminals are completely tightened before inserting the plug.
• The speaker terminals will need to have the round pips removed before you can insert a banana plug into them.

BASIC CONNECTIONS

• Any ‘line level’ source equipment can be connected to the audio inputs on the AXR (A1 to A3).
• The diagram below shows the basic connection of the AXR to a CD player using the A1 analog input and a pair of loudspeakers.

• The diagram below shows the basic connection of the AXR to a turntable via the Phono input.
• This unit has a built-in Phono preamplifier (Phono Stage), so if your turntable does not possess its own Phono Stage, you may connect the record player to the input on the rear of the unit marked ‘Phono’.
• If your turntable does have a built-in Phono stage or you are using an external version, you should connect to any of the other analogue inputs, as the ‘Phono’ input may produce an unwanted distortion.

Note: Do not connect a non-phono source to the phono input.

• The Sub Out is for connecting to the LFE/Sub input of an active subwoofer.
• The diagram below shows how to connect the AXR to an active subwoofer via the LFE/Sub input on the subwoofer.

SPEAKER B CONNECTIONS

• The Speaker B connections on the back of the amplifier allow for a second set of speakers to be used (i.e. speakers located in another room).
• The Speaker A/B button on the front panel and remote control allows the 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.
• Either A or B, or both A and B may be selected for use.

Note: When using two pairs of speakers, use speakers with a nominal impedance of 8 ohms each.

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 focused sound.
Note

• Speakers A and B must both be selected on the front panel of the unit for this type of connection to work.
• Remove the bi-wire link on the speaker terminals before connecting. Refer to your speaker’s manual for more information.

Aerials
Last updated: July 29, 2022, 10:29. Revision #9838

Note: The AXR 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.
