About

About Boulder Amplifiers, Inc.

Boulder was founded in 1984 and is the last high-performance audio manufacturer operating in North America to still perform all of its own design, engineering and manufacturing in-house. While this form of production may be more costly than more common outsourcing, the resulting quality control and reliability of the finished products are never compromised.

In 2016, Boulder moved into a new, purpose-built manufacturing facility to increase manufacturing efficiency and offer space for expansion to meet the needs of future growth.

Unpacking

Unpacking and Care

The 2120 system is very heavy. Please use care when lifting and installing the separate sections to avoid personal injury or damage to the casework.

The 2120 D/A Converter section weighs 63 lbs. (28.6 kg). If possible, use two people to unpack and move it into position. The 2101 Power Supply section is front-end heavy. Please be aware of this to avoid any accidental damage.

Save all packing materials. Both the D/A Converter and Power Supply are shipped in a foam wrap to protect the fine finish of the casework. Try not to damage this wrap in case the unit must be transported elsewhere in the future.

Before You Start

The 2120 system comes in two assemblies that must be put in place and connected: the 2120 D/A Converter and the 2101 Power Supply.

You should have received two large, heavy boxes. The pieces included inside them are:

• 2120 D/A Converter.

A. Accessory Box #1 with the D/A Converter containing:

• DC power cables.

B. Accessory Box #2 with the D/A Converter containing:

• Handheld IR Remote Control.

• Instruction Manual.

• Digital Adapter.

• 2101 Power Supply.

a. AC Power Cord.

If any of these pieces are missing or damaged, please contact your authorized Boulder dealer immediately before continuing the installation.

Unpacking

How to clean the casework

Use only a soft, lint-free cloth moistened with plain water.

Never use any type of chemical cleaner unless recommended by your dealer or the Boulder factory.

Do not use bleach! Bleach will remove the anodized surface of the casework.

Never use any type of abrasive to clean the casework.

If you have any questions, please contact your authorized Boulder dealer.

Placement and Installation

Because it is very heavy, the 2120 system must be placed on a sturdy, stable surface.

The 2120 must have a visible line-of-sight between the front panel and IR remote control to work.

Do not place in an enclosed rack with no ventilation. Both the 2120 and

2101 must have at least 3 inches (8 cm) of airspace around their chassis for proper cooling and airflow.

The 2101 should be placed at least 10 inches (25.4 cm) away from the

2120. The 2120 should not be stacked directly on top of the 2101 to allow for proper ventilation of the power supply.

Be sure to leave access to the AC mains and DC power cables when installing. Depending on how easy it is to access the back panels of the

2120 and 2101, it may be wise to preinstall the cables on one component before installing.

2-2

Connections

Connecting Source Inputs

The 2120 can be connected to many different types of digital sources and will provide the ultimate in sound quality for each.

When connecting various sources, make a list of what component is connected to each input so that you do not forget the order in which they are connected. You will be able to name the inputs on the screen later (see

page 8-10) for easy identification and this list will be very helpful at that time.

The 2120 can be set up with many custom digital input combinations to suit your particular system needs. These input combinations are modular and can be fitted at the factory or by your dealer to match your individual setup.

To purchase or learn more about additional digital input options, please contact your authorized Boulder dealer.

Connections

Connections from sources such as a CD transport, DVD player, Blu-ray player, Digital Recorder, or Cable/Satellite Receiver can be made to the

AES/EBU, S/PDIF and Toslink (EIAJ Optical) connections. These inputs do not need to be configured and are active as soon as they are connected to an active source. Once the source device has been powered up, all playback control will be handled by the source device itself.

HDMI connections can carry very high resolution digital audio from audio and video devices. When connected to the 2120, the HDMI connection will automatically configure the source component to transmit a stereo audio signal. Once the source device has been powered up, all playback control will be handled by the source itself. HDMI is also able to pass along a small number of control commands. The control command compatibility will vary depending on the product being connected to the 2120. If installed, the HDMI module includes two inputs and one pass-through output. The pass-through output can be routed to a display device or external surround processor. This will enable the 2120 to process the audio portion of the

HDMI signal and allow the secondary device to process any video signal present.

The Ethernet connections are for Internet access to provide updates to the 2120, access to online media streaming, or a networked DLNA/UPnP music streaming system.

To connect, you will need a router and/or a DLNA compliant media server.

When streaming music from a DLNA network, functions such as track or album selection, volume, play, stop, pause, etc. can be controlled by the system’s Control Point application. For further information about Internet streaming or DLNA/UPnP, please contact your authorized Boulder dealer.

3-3

Connections

The 2120 supports two types of USB inputs, A and B. These connectors are for two different types of digital data feeds.

USB Type A USB Type B

USB Type A

The USB Type A connector is for simple storage devices and will allow the 2120 to play music from a storage device. These types of devices can include USB Flash memory sticks and some USB hard drives.

NOTE: Depending on your computer’s operating system, some memory devices may be formatted for file systems that are not compatible with the 2120. Please contact your authorized Boulder dealer for further information.

For a memory device, control and library navigation will be handled by the 2120 or a control point application in the same way it controls network streams for servers.

Because of the different types of library organization on Type A devices, your music may be organized in different ways on each device.

USB Type B

The USB Type B connector is for connecting a computer to stream digital music to the 2120. This allows you to stream the existing music library on your computer by using streaming media software.

3-4

Connections

Connecting the 2120 to the 2101 Power Supply

Connect the DC cables from the 2101 power supply to the 2120 D/A

Converter. Because the cable connectors are keyed, they cannot be installed incorrectly.

Connection to AC Mains

Connect the AC power cord to the 2101 and plug it into your AC mains.

CAUTION: Do not turn on the 2101 until all DC power connections have been made. It is important to never connect or disconnect any of the DC power cables when the unit is powered ON or damage may occur, even when the 2120 is in Standby mode! Always turn the unit OFF from the rear panel of the 2101 power supply or disconnect the AC mains power cord before disconnecting any of the DC power cables.

Connecting the Analog Outputs.

Connect the Left Analog and Right Analog interconnects from the 2120 to your preamplifier or amplifier. To maintain the best sound quality, Boulder recommends that balanced audio connections always be used.

Connecting to an Unbalanced Preamp or Power Amplifier

A special cable is required to make this connection. This cable connects pin 1 to the shield and pin 2 to the center pin of the RCA. It leaves the negative output (pin 3) unconnected.

Connecting the unused output pin (usually pin 3) to ground will cause excessive ground currents and degrade performance. Use an ohmmeter or continuity checker to determine how your cable is wired.

LINE INPUT

3-7

Connections

Connecting to a Network:

To connect a network to the 2120 for Internet music or UPnP streaming, you will need a network with an active Internet connection. This will enable you to access subscription Internet music services or music from a media server and allow the 2120 to automatically download software updates as necessary.

Connect a network cable between the 2120 and the router. Use either

Ethernet connector; it does not matter which one you use.

When connecting an active network to the 2120, you will see the following message on the 2120’s display:

A new network connection has been detected.

Do you want to reconfigure the network?

Change the option to YES and press the Enter button. The 2120 will reconfigure itself for networked operation and return to normal operation quickly.

3-8

Connections

If your network connection is disconnected or interrupted for any reason, you will see the following message on the 2120’s display:

External network connection is no longer available!

Do you want to reconfigure the network?

If you have disconnected the network and it will not be reconnected or it will be connected to a different router, change the option to YES and press the Enter button. The 2120 will reconfigure the Ethernet connection for stand-alone use.

If you have only temporarily disconnected the network and will not change the network that the 2120 is connected to, change the option to NO and press the Enter button, or just reconnect the network and the screen will disappear.

It is important that the network is configured correctly because the 2120 always uses an internal network, even when it is not connected externally.

If you are having problems with your network or have further questions about network streaming, please contact your authorized Boulder dealer.

Ethernet

Playing from a UPnP/DLNA Networked Audio System

The 2120 is able to play music files over a computer network. This type of music streaming adheres to the UPnP (Universal Plug and Play) protocol, which is a part of DLNA (Digital Living Network Alliance). The 2120 also adheres to the OpenHome Standard.

DLNA media streaming guarantees bit-perfect music transfer, unlike most other media streams.

OpenHome is an open standard for networked digital streaming, providing an advanced feature set for networked home audio devices.

A typical UPnP streaming music system is made of the following

pieces:

• Server: The place where music files are stored.

• Renderer: Another way of saying digital-to-analog converter, or the component that receives the music files and converts them to analog for playback.

• Control Point: A software application that communicates with the server and the renderer and coordinates the music being sent, received and played back. The control point also allows you to browse a music library.

• Router: The device that connects all of the parts of the system and allows them to communicate with each other.

6-1

Ethernet

The server can be a NAS drive, a computer, or a dedicated media server.

Servers can also import music from the Internet, discs, or other computers.

In your system, the renderer is the 2120. The 2120 has an internal control point utilizing the front panel display and push buttons.

NOTE: Because there are many different ways to configure a UPnP system, this manual will only explain how the system works. If you are unsure how to put together a UPnP system or would like to learn more, please contact your authorized Boulder dealer for additional information.

The server and the renderer are connected to the router by network cables.

Boulder recommends that CAT-6 or CAT-7 cables be used because they offer added reliability.

Control points can be connected to the system wirelessly through a WiFi router. They can also reside on computers.

After everything is connected together, they should be powered up in

this order:

1. Router

2. Server

3. 2120

4. Control Point

Once everything is powered up, it will take a few minutes for everything to communicate. After that, it will be possible to use the control point to look at and choose music on the server and send it to the 2120.

6-2

USB

Playing from a portable USB Memory Device

Music on a portable USB memory device can be played by connecting it to the 2120’s USB Type A input. The rear panel of the 2120 has one standard

USB Type A input. If additional USB Type A connections are desired, a powered USB hub can be connected to the 2120’s USB Type A input.

To play music files from a USB memory device:

Insert a USB memory device into the USB connector on the rear panel.

To make it easier to insert a USB thumb drive after the 2120 is installed, a

USB extension cable can be used so that the connection can be accessed from the front of the unit.

The front panel display of the 2120 will show the following:

7-1

USB

There are two read options for playing from a USB memory device. They are:

Read Only: Yes Prevents the 2120 from writing a catalog file onto the memory device. This option assures that the USB device will not be modified or corrupted, however, the 2120 will have to build a database and catalog of files for the USB device every time it is inserted.

Read Only: No This allows the 2120 to write a catalog file onto the USB memory device so that there will be faster access to the files each time it is inserted.

When the 2120 plays music from a USB memory device, it builds a directory catalog of the tracks on the storage device, and presents them as a UPnP media server.

The default option is Read Only: No

7-2

USB

There are two sharing options for playing and writing to a USB memory device. They are:

Create Network Share. This option will allow the USB memory device to be seen by most networked computers. You can then read and write files to the USB memory device through the 2120 using these computers.

Do Not Create Network Share. This option does not allow an external computer to read and write to the USB memory device through the 2120.

The default option is Create Network Share: Yes

Once the read and sharing options are selected, press the Select button.

If you select Yes, the 2120 will share all of the files on the USB memory device.

NOTE: The more files on the memory device, the longer the 2120 will take to create a catalog.

7-3

USB

When a catalog file has been built, the USB memory device will appear as an input option on the front panel in the Input Select screen. Navigate to the desired USB input and press the Select button to select the USB memory device. You will then be able to browse the USB memory device using the front panel navigation buttons. It is also possible to select and play music from the USB memory device using a control point by selecting the USB device as the server in the listing of available servers.

Eject

To eject the USB memory device, navigate to the Input Select screen. Press the Eject button on the 2120’s front panel and wait for the USB memory device to disappear from the list of available inputs before removing it.

CAUTION: You must always eject the USB memory device from the front panel or damage to the files contained on it may occur! The benefit of using Read-Only is that it is very difficult to damage the USB memory device by just removing it.
