•A headphone output

(post volume and balance controls).

1.1.3 Controls

1.2 The CD Player

NaimUniti 2 incorporates a CD player based on the same swing-out CD drawer and transport used in other Naim CD players. The transport is able to play standard “Red Book” CDs and CDR discs. CD track order can be programmed or tracks can be shuffled (played randomly).

1.3 The Multi-mode Radio

The NaimUniti 2 multi-mode radio combines an FM/DAB (Digital Audio Broadcasting) tuner and an internet radio (iRadio) player. A total of 40 radio stations across all three modes can be stored as presets. In FM and DAB mode stations are tuned by NaimUniti 2 scanning the respective transmission bands. In iRadio mode NaimUniti 2 receives data streams and a list of available radio stations from

a dedicated internet server. iRadio requires broadband internet access via a home network connection.

The NaimUniti 2 DAB module incorporates full broadcast and station display capabilities. The FM module is fully RDS (Radio Data System) capable.

Note: DAB and RDS broadcasts are not available in all territories.

1.4 The UPnP™ Audio Interface

NaimUniti 2 can connect to a home network and play audio files stored on UPnP™ drives.

1.5 The USB/iPod Interface

The NaimUniti 2 preamplifier provides volume, balance, input selection and mute control from either the front panel or the supplied remote handset.

1.1.4 Speaker Outputs

NaimUniti 2 incorporates a stereo power amplifier rated at 70 Watts per channel into 8 Ohms. The power amplifier is designed to drive one pair of speakers via the sockets on the NaimUniti 2 rear panel.

NaimUniti 2 incorporates a front panel USB interface socket that enables audio files stored on USB memory sticks and Apple iPod models to be selected and played.

Note: 5th generation and later, and all iPod touch models, are compatible with the NaimUniti 2 USB interface.

Note: Earlier iPod and other portable music players may be connected from their headphone sockets to NaimUniti 2’s front panel analogue input using a 3.5mm stereo jack cable. Player control via NaimUniti 2’s user interface will not however be possible.

NaimUniti 2 Installation and Connection

2 NaimUniti 2 Installation and Connection

NaimUniti 2 should be installed on an equipment stand intended for the purpose. Do not stand it directly on top of another item of equipment and ensure it is well ventilated. Care should be taken to ensure that it is level. It should be installed in its final location before connecting cables or switching on. NaimUniti 2 has no standby mode and is intended to be left switched on.

A transit screw on the underside of the NaimUniti 2 case should be removed before use and replaced if the unit is to be moved. This transit screw must not be used in any other Naim product. Handle NaimUniti 2 with extra care once the transit screw is removed.

Connecting NaimUniti 2 to mains power and to a variety of audio peripherals and sources is described in the following paragraphs. Diagram 2.1 illustrates the NaimUniti 2 rear panel connection sockets.

2.2 Mains Power Connection

Connect NaimUniti 2 to a mains power socket using either the mains cable supplied or a Naim Power-Line.

2.3 FM/DAB Aerial Connection

In order to enable high quality FM and DAB radio, NaimUniti 2 requires a strong, interference-free radio signal. Its rear panel FM/DAB Aerial socket must be connected, via 75 Ohm low-loss coaxial cable, to a suitable aerial. The aerial should be mounted clear of large obstructions and as high as possible; ideally on a roof.

Note: Your local retailer should be able to offer advice on a suitable aerial and aerial installer.

2.4 Audio Signal Connections

2.4.1 Audio Signal Inputs

NaimUniti 2 provides five stereo analogue inputs and five S/PDIF digital inputs including one combined analogue/ digital input socket. Connection to the inputs is made via a variety of socket types. The following table lists the inputs and their socket types:

Input	Type	Socket
an. 1	Analogue	RCA phonos
an. 2	Analogue	RCA phonos
an. 3	Analogue	RCA phonos
phono	Analogue	240° 5 pin DIN
front panel	Analogue	3.5mm jack
	Digital	3.5mm mini-TosLink jack
dig. 1	Digital	Coaxial (RCA phono)
dig. 2	Digital	Optical (TosLink)
dig. 3	Digital	Coaxial (RCA phono)
dig. 4	Digital	Optical (TosLink)

Note: The Phono DIN socket carries a power supply output intended to power a Naim phono preamplifier. A turntable cannot be used with NaimUniti 2 without an external phono preamplifier.

Note: The front panel analogue/digital jack socket can accept both conventional analogue 3.5mm plugs and mini-TosLink optical digital plugs. It will automatically identify the type of plug inserted and handle the signal appropriately.

Always use high quality interconnect cables to connect sources to NaimUniti 2 inputs.

NaimUniti 2 Installation and Connection

2.4.2 Audio Signal Outputs

NaimUniti 2 provides audio signal outputs for a variety of applications. Connections to the outputs are made via the socket types listed in the following table:

Output	Type	Socket
Preamp out	Analogue stereo	4-pin DIN
Sub out 1	Analogue mono	RCA phono
Sub out 2	Analogue mono	RCA phono
Line out	Analogue stereo	RCA phonos

Note: The preamp output is intended for connection to an upgrade or second power amplifier. The output is taken after the NaimUniti 2 volume and balance controls so a power amplifier connected to it will respond to NaimUniti 2 volume and balance control changes. The output always reflects the selected input signal.

Note: The two subwoofer outputs are mono and unfiltered. They are taken after the NaimUniti 2 volume control so subwoofers connected to them will respond to NaimUniti 2 volume control changes. The outputs always reflect the selected input signal and can be switched on or off in the Speakers setup menu.

Note: The stereo line output is intended to be connected to a recording device. It is taken before the NaimUniti 2 volume and balance controls so does not reflect volume or balance control changes. The output always reflects the selected input signal.

2.5 Speaker Outputs

A set of stereo speaker connection sockets is provided on the NaimUniti 2 rear panel. Custom Naim Audio loudspeaker connectors are supplied to make the connection and in order to comply with current European safety regulations these should always be used. Naim

Audio speaker cable will provide the best results, however, a range of speaker cable types may be used without

risk of damage to the amplifier. Contact your local Naim retailer for further advice. Use equal lengths of speaker cable for each channel.

Ensure when connecting speakers that they are “in phase”. That is, the positive and negative connection orientation at both the speaker and amplifier ends of the cable is the same for both channels.

2.6 Headphone Output

NaimUniti 2 is fitted on its front panel with a 3.5mm stereo headphone socket. Insertion of a headphone plug will mute the speaker outputs.

Note: NaimUniti 2 controls and stores volume settings separately for headphones and speakers.

2.7 Signal Ground Switch

NaimUniti 2 is fitted on its rear panel with a Signal Ground switch offering two positions: Chassis or Floating. Select the Chassis position unless NaimUniti 2 is connected

in a hi-fi system incorporating another earthed source component, or mains “hum” is audible through the loudspeakers. Contact your retailer, distributor or Naim for advice if necessary.

Note: “Connected” in the context above means an analogue audio signal cable that includes an earth connection.

Note: All Naim CD players are earthed so the Signal Ground switch should be set to floating if one is connected in the system.

No damage will be done if the wrong Signal Ground position is chosen, however the system sound quality may be compromised.

2.7.1 General Audio Connection Notes

The NaimUniti 2 negative analogue input and output connections for each channel are common. The mains earth (ground) should always be connected regardless of what other equipment is used. The mains earth primarily grounds the case and the electrostatic screen within the transformer, and is only connected to the signal negative if the Signal Ground switch is set to Chassis. In order to avoid hum loops, the signal negative of the whole system should be connected to the mains earth in one place only.

2.8 USB/iPod Interface

NaimUniti 2 is fitted with a front panel USB interface intended for the connection of Apple iPod models and USB memory sticks carrying audio files. The USB interface should not be used for any other purpose.

Depending on the setup options chosen (see Section 4.3.6), iPod batteries will be charged when connected to the USB interface.

2.9 Network Connections

2.9.1 Wired Network Connection

NaimUniti 2 is fitted on its rear panel with a standard RJ45 Ethernet socket. This socket enables NaimUniti 2 to join home networks via a network router to access

internet radio data streams or to play audio files stored on appropriately configured UPnP™ servers.

Ethernet-over-mains hardware may be used and provides a simple and convenient method of wired home network connection. However, depending on mains wiring factors specific to each home environment, the presence of network data on the mains supply may compromise overall system sound quality. If any sound quality compromise is found to be unacceptable, dedicated network cabling should be installed or wireless networking should be employed.

NaimUniti 2 Installation and Connection

2.9.2 Wireless Network Connection

If NaimUniti 2 is to connect wirelessly to the home network the supplied Wi-Fi antenna must be fitted to the rear panel wireless antenna socket. Wireless configuration will also

be necessary before NaimUniti 2 is able to connect to the network. See Section 4.6.1 of this manual.

2.9.3 Network Settings

NaimUniti 2 is set up when originally shipped not to require any on-site network configuration but to connect to a network automatically (it uses DHCP by default). However, if your NaimUniti 2 has been previously used, its network configuration may have been altered leaving it unable to connect automatically. If this appears to be the case ensure that DHCP is selected in the Network Settings menu

and re-start NaimUniti 2. If problems still persist contact your retailer, installer or Naim Audio directly. See Section 4.6.

Note: Before reporting network connection problems carry out a Factory Reset operation and try again. Select Reset All Settings from the Factory Settings setup menu. See Section 4.10.

Note: A NaimUniti 2 switched on without a working wired network connection will only be able to connect to

a home network wirelessly. To use an Ethernet (wired) connection, switch NaimUniti 2 off, connect the network and switch it on again.

Note: For internet radio to operate NaimUniti 2 requires connection to a broadband internet service via a router/ modem with a built-in firewall.

2.10 Control Sockets

The NaimUniti 2 is fitted on its rear panel with a 3.5mm jack

Remote In socket and a mini-USB interface socket.

The Remote In socket can be used for RC5 remote control of the NaimUniti 2 via a wired connection or a remote IR repeater.

The mini-USB socket enables firmware upgrades and diagnostic tests to be carried out. Contact your Naim retailer for more information if required.

Note: The mini-USB interface is not intended for the connection of USB memory devices.
