4 – DX1208

2. INTRODUCTION KEY FEATURES

The DX1208 is a 12-input, 8-output DSP matrix mixer designed for use in a variety of commercial and installed sound applications such as churches, courtrooms, convention centers, and hotels. Eight inputs are mic/line capable, with selectable 48-volt phantom power provided for each input.

These 8 inputs and the 8 outputs are accessed using Euroblock detachable connectors. Four additional inputs on unbalanced

RCA connectors allow the user to “stack” inputs (inputs 5-8), increasing the number of audio sources that can be connected.

An additional four digital inputs are available on S/PDIF connectors with sample rate conversion to 48 kHz. All 12 inputs are included in the audio matrix and can be assigned

DSP functions prior to distributing signal at line level.

The DX1208 can also receive up to 6 logic inputs and send up to 3 logic outputs, programmable via the included DX

Navigator control software. Control of the DX1208 via third party systems (i.e., AMX and Crestron) is easily attained with an RS-232C serial connection (DB9) on the rear panel. Two

RJ-45 connections are provided as well for linking multiple (up to eight) DX Link enabled products together in a ring network topology.

A remote control port (RJ-25 connector) is included on the rear panel, facilitating the connection of two different types of remotes (UR-1 and UR-2), all mounted on wall panels. Up to 10 remotes can be attached to the DX1208 (more when external power is supplied), and each is individually addressable and configurable.

The DX1208 is supplied with DX Navigator control software that allows access to all of the system’s settings and configurations using a personal computer (PC). The expected range of user-adjustable processing, such as EQ filters, gates, compressors, limiters, AGC, ducking and priority assignment, delay, gain, and crossovers are included. The Automix feature employs a gain sharing automixer, to keep the overall system gain constant. In addition, up to 24 programmable presets are available per DX1208, which can be used to store and recall frequently used settings. The programming interface is flexible, with connection via the USB port on the front panel, or the

Ethernet jack or DB9 connector on the rear panel.

The DX1208 is UL and CE approved. It is designed for continuous use in professional fixed installation systems and employs a universal power supply (100-240 VAC, 50/60 Hz).

13. RS232

This is an RS-232C port on a 9-pin (DB9) connector. It connects to a personal computer or other compatible control system for external control of the DX1208 settings.

This may be used instead of the USB port or the Ethernet connection for programming the DX1208.

14. ANALOG OUTPUTS A-H

Eight balanced line-level outputs are provided on these

Euroblock connectors, labeled A-H.

15. ANALOG INPUTS 1-8

Connect eight balanced mic or line-level inputs to these

Euroblock connectors. The input gain is adjusted in the DX

Navigator software application to accommodate a mic or line-level signal. 48V phantom power can also be applied to a microphone input by activating it in the DX Navigator

DX1208 user-interface.

16. ANALOG INPUTS 5-8

These RCA connectors accept unbalanced line-level inputs (–10 dBV) to accommodate consumer sources such as CD or MP3 players. The left and right inputs for each channel are summed to mono internally. It is possible to have a signal connected to both balanced (Euroblock) and unbalanced (RCA) connectors for inputs 5-8. The signals are summed together in the analog domain, just prior to A/D conversion.

17. S/PDIF IN 9/10 and 11/12

These RCA connectors are used to connect S/PDIF digital inputs to the DX1208. The sample rate is automatically detected and converted to 48 kHz for internal processing.

18. LOGIC I/O

The DX1208 provides six logic inputs and three logic outputs on Euroblock connectors. The inputs can be used to control a variety of DX1208 functions via external switching, such as preset recall or channel muting. The outputs can be used to provide logic for external indicators and switches to indicate a range of internal settings and conditions.

Each logic input and output is comprised of two pins, the active pin and ground. See “Connecting the Logic I/O” on page 8 for suggested logic input and output wiring examples.

3. HARDWARE INSTALLATION

The DX1208 ships with rack ears installed, which allows the unit to be mounted in a standard 19" rack, requiring one rack unit (1.75"). When mounting in a rack, use plastic washers to protect the rack ears from the mounting screws.

Note: Since the DX1208 is convection cooled with ventilation slots on the sides and top, please allow one rack space above the DX1208 to allow proper ventilation.

If you do not rack mount the DX1208, you may remove the rack ears if desired.

CONNECTIONS

Connecting Balanced Sources

Use high-quality three-conductor cable for balanced input connections. The better the shield, the better the audio signal is protected from induced EMI and RFI.

Note: With screw-down Euroblock connectors, it’s best to use stranded wire that is not tinned. Solder can “flow” under the pressure of the screw-down terminal and cause the connection to become loose.

Ethernet connection

An RS-232C serial port is also available for connecting a PC or other controller. This is a DB9 female connector on the DX1208 rear panel and requires a cable with a DB9 male connector on the DX1208 end. The DX1208 is configured as a device or Data Communications Equipment (DCE), which is to be connected to a controller or Data Terminal Equipment (DTE) and be controlled.

Connecting the DX LINK RX/TX

These two RJ-45 connectors are provided to connect DX

Link enabled devices together and transfer audio among the devices. Up to 16 channels of audio can be transmitted over the DX link ring network using shielded CAT5 cable, and up to

8 DX Link devices can be connected together.

When two or more DX1208s are connected together using

DX Link, one must be configured as a Master and the rest as

Slaves. This is done in the Settings window of DX Navigator, and the audio is managed in the DXLink window.

Note: Although the DX Link uses Cat5 or Cat5e network cable, this is not “audio over Ethernet” and cannot use standard network hardware such as switches or repeaters.

Connect the TX connector on the master device to the RX connector on the first slave device. Then connect the TX on the slave to the RX on the next slave, and so on. Connect the TX on the last slave back to the RX on the master to complete the connection.

RS232 connection

DX LINK connection

A separate document is available that provides information on port settings and control protocol for the RS-232 connection. Visit www.eaw.com for more information.

Connecting the REMOTES

An RJ-25 connector on the rear panel is used to connect the optional remote control peripherals. You can connect up to 10 remotes on the remote bus. More remotes can be connected to the remote bus, provided that external power is supplied to the additional remotes. Refer to the documentation provided with the remote control units for more information.

There are currently two types of remote controls available for the DX1208. Each remote has two RJ-25 connectors, one for connecting the remote bus from the previous device and the other for connecting to the next device. Each remote also has an eight position DIP-switch for assigning its unique address.

UR-1

The UR-1 has a rotary encoder and a function button to fit a single-gang decora plate, and mounts in a single-gang electrical box.

AC POWER CONSIDERATIONS

The DX1208 has a built-in universal power supply and can accept an AC voltage ranging from 100 V to 240 V. Each

DX1208 draws an average of 0.5 amps of AC line current at

120 VAC.

Warning: Always use a 3-conductor AC power cord with a safety ground connection. Never remove the ground pin or attempt to bypass it. This is very dangerous.

UR-1

The encoder is used to increase or decrease the volume of an input or output. A ring of 15 LEDs surrounding the encoder indicates the relative audio level. The function button can be programmed for a number of actions, such as "Mute an Input" or "Recall a Priority." When the function is activated, the LED in the button lights. Programming is done in the Remotes window of DX Navigator.

UR-2

The UR-2 has four function buttons to fit a single-gang decora plate, and mounts in a single-gang electrical box.

Each button can be programmed to perform a different action.

When a function is activated, the LED in the button lights.

Programming is done in the Remotes window of DX Navigator.

4. SOFTWARE INSTALLATION

ESTABLISHING COMMUNICATION

OVER USB

There are a few steps required to establish communication between DX Navigator and the DX1208.

1. Click “Tools” in the top menu bar and select

“Communications” from the drop-down menu. The

Communications window opens.

5. Double-click the DX1208 icon in the “Found Devices” tab to open the DX1208 interface. Click on the tabs across the top of the DX1208 interface to open individual screens for accessing controls and settings. The tabs include Input,

Priorities, Automix, Output, DXLink, Logic I/O, Remotes, and Settings.

6. Refer to the Help file for detailed information about each of the screens. To open the Help file, return to the DX

Navigator window, click “Help” in the top menu bar, and select “DX1208 Help.”

COMMUNICATING OVER ETHERNET

2. Click the “COM Port” radio button and select the COM Port that is assigned to the USB port that is connected to the

DX1208.

If you are not sure which COM Port is being used, open the Device Manager on your computer, locate “Ports (COM

& LPT)” in the list and click the “+” sign in front of it. You should see “EAWC DX Family USB Serial Port” followed by a COM port number. This is the number you should select in

DX Navigator’s Communications window.

Click “OK” to close the Communications window.

3. Click “Go Online.” DX Navigator will begin to query the

DX1208 and the COMM LED on the DX1208 should light.

4. Once communication is established, the DX1208 icon appears in the “Found Devices” tab with a green checkmark in front of it.

You can connect your computer to the DX1208 directly with an Ethernet connection, or indirectly over an Ethernet switch or local area network (LAN).

Direct Connection

The DX1208 can be connected directly to your computer using a crossover Cat5/Cat5e Ethernet cable.

When the DX1208 is connected via Ethernet, it requires an IP address and will initiate a DHCP (Dynamic Host

Configuration Protocol) request for an IP address from a DHCP server. Since no DHCP server exists on a direct connection, it is necessary to assign a static IP address to the DX1208 in order to communicate over Ethernet.

To assign a static IP address:

1. Connect your computer to the DX1208 using the USB port.

2. Open DX Navigator, click “Go Online,” and open the

“Settings” tab in the DX1208 GUI. In the IP section, select

“Static IP” and enter 169.254.xxx.xxx, where xxx can be any number between 1 and 254. This is a private IP address used for link-local addressing, but you can enter a privateuse IP address if you prefer. Remember the number that you entered. You will need it again.

In the Subnet field, enter 255.255.0.0.

Note: Refer to RFC-3927 for information on link-local addressing, and RFC-1918 for information on address allocation for private internets.

3. Go offline and turn the DX1208 off.

Note: You must power cycle the DX1208 in order for the

Static IP address to take effect.

4. Connect the DX1208 to your computer with an Ethernet cable and turn the DX1208 on.

5. In DX Navigator, click “Tools > Communications” in the top menu bar.

6. Click the “Specify Target IP Addresses” radio button. Enter the same IP address that you entered previously for the

DX1208 and click “Add” to add it to the list of IP Addresses that DX Navigator will search for when it goes online.

7. Click “OK.” Click “Go Online” and the DX1208 icon will appear in the “Found Devices” tab.

Indirect Connection

If you have multiple DX1208s installed in a system, you may want to have them connected together in a LAN. This allows you to connect your computer to the LAN and access each DX1208 individually without having to physically change connections.

Again, the DX1208 will send out a request for an IP address. If there is a DHCP server on the network, it will assign a unique IP address to each DX1208 on the network. If there isn’t a DHCP server, then a unique static IP address will have to be manually assigned to each DX1208 (see “To assign a static

IP address” above).

Once an IP address has been assigned to each DX1208:

1. Open DX Navigator and click “Tools > Communications” in the top menu bar.

2. Select “Obtain IP Addresses By Broadcast” and click “OK.”

3. Click “Go Online.” DX Navigator will find all devices on the network with an IP address and they will appear in the

“Found Devices” tab.

Note: The “Obtain IP Addresses By Broadcast” may not work with Windows Vista yet. If you are running the Vista operating system, it may be necessary to assign a static IP address to each DX1208, even if there is a DHCP server on the network, and select “Specify Target IP Addresses” in the

Communications window (see “To assign a static IP address” in the previous section).

COMMUNICATING OVER RS232

A rear panel RS-232C serial port is provided for additional third party control options. Nearly every parameter that can be controlled with DX Navigator can also be controlled using a third party controller (i.e., AMX and Crestron models).

Port settings and control protocol will be provided in a separate document. Visit our website for more information at www.eaw.com.

UPGRADING THE FIRMWARE

From time to time, EAW Commercial will release upgrades for the internal operating firmware in the DX1208. This can be downloaded from our website (www.eaw.com) to a

PC-compatible computer along with instructions on how to upgrade the firmware.
