Setup and installation

ATTENTION!
Before installing your new digital director, your DAC firmware must be updated to 3.0.2.1 or later. Otherwise,
The Digital Director will not fully function.

Step 1 – New firmware

If needed, update your DAC firmware to the latest available version. The latest DAC firmware enables new functionality with the digital director. Firmware update files and instructions can be found at: www.msbtechnology.com/Support

Step 2 – Swap digital input modules

***UNPLUG YOUR AUDIO SYSTEM***
Install the provided Pro ISL input module into slot ‘B’ of your DAC and install the provided Control Link module into slot ‘A’. Then, install any other digital inputs from your DAC into your Digital Director. When installing and removing input modules please use the tips below for proper handling to reduce risk or damage to your MSB system.

About the 4 input module slots
The Digital Director has four input module slots. They are labeled A through D. Digital input modules can be placed in any position. However, the control link module and Pro ISL input module in your DAC must be installed in slot A and B. Each module is completely self contained. It is recognized by the Digital Director and identified on the DAC display.

Removing and Installing Modules
Removal and installation of modules is a completely tool free process that is easily performed at the back of the unit. Under the lower lip of each module is a lever arm. Simply pull the lever out and away until it is perpendicular with the back of the unit. Then gently, but firmly, pull the module lip and lever until the module releases and slide it out of the unit.

Module Handling
It is important that you refrain from touching the circuit board or rear connector of any input module when removing or installing any input from your unit. When handling these modules it is important that you only contact the metal case of the module or the front edge of the module where the cam arm is located. Improper handling of your modules can result in static shock and damage to the module or unit.

Step 3 – Connect your 12 volt trigger

After placing your Digital Director into your system, link the unit to one of your existing MSB powerbase units with the provided 3.5mm mini jack cable. Then set the power control switch on the bottom of the unit to the “Linked” position. This allows the primary powerbase of your system to control the secondary one as well as the Digital Director without them having to be turned on/off separately.

The diagram above is only a visual example and the actual connections may vary in your system. The specific order in which the units are connected does not affect how the 12 volt connections will function. The only requirements are that each unit is connected to a 12 volt trigger port of another unit in the chain. Only one unit is set to the normal ‘N’ position while all other units are set to the linked ‘L’ position.
The unit that is switched to the ‘N’ position will be the main control unit that will receive any power commands sent via the MSB remote or by the power button located on the front of the unit. Any of the units connected via the 12 Volt trigger connections and set to the ‘L’ position will power on and off only when the main control unit is used. The remote IR and button inputs will be deactivated.

Step 4 – Make cable connections

After swapping your input modules, the last step is to make a few connections. A description of each connection can be found in the table below as well as a detailed connections diagram on the following page.

Power	The Digital Director has a built-in high performance power supply. The power supply automatically detects and switches between 240V and 120V. This is not a switching supply that works at any voltage, but a linear supply with automatic switching of the transformer leads. The unit is switched on and off with a button on the front or via the IR remote. Plug in the provided AC cable to the back of the unit.
Input Modules	The Digital Director comes with a Pro ISL Input Module and a MSB Control Link Module. Simply remove the digital input modules from your DAC and swap them with the modules in your Digital director. Connect your digital input(s) to the appropriate module(s) in the digital director. The frequency and bit depth of the incoming signal will be displayed on the front panel of your DAC.
Pro ISL Output	Connect the Pro ISL output from your Digital Director to the Pro ISL module in your DAC.
Control Link	Connect the Control Link connector from your digital director to the control link module in your DAC

When installed properly, your system should look like the example above. The digital inputs installed in your digital director may vary depending on what sources are in your system, However; the only modules that should be installed in the DAC will be the provided Pro ISL and Control Link modules as well as any analog input modules you may have in your system.

Digital Director interface
There is one button on the front of the unit as well as two control features just under the front of the unit on the bottom.

LED indications	White – Power on. Red – Power off. Amber – Linked mode, 12 volt trigger controlled. Flashing Amber – Over-voltage protection.
Display brightness	This is a rolling wheel to control the brightness of the power indication light
Power control	Normal – This sets the unit as the 12 volt trigger master. Linked – This sets the unit as the 12 volt trigger slave. The ‘master’ unit will control this unit.

Digital Director Jackpanel “Status” Light

There is a single status light located on the jackpanel next to the Pro ISL output. The LED indications are listed below.

Flashing Red	Advanced digital filtering Disabled – The Director is functioning in “passthrough” mode.
Flashing Green	Advanced digital filtering is Enabled – The director is functioning in “filtering” mode.

Digital Director menu options
The following menu options will be viewable in your DAC menu when a digital director is detected in your system. The Digital Director needs to be set to the ‘passthrough’ setting whenever you are updating the firmware in your DAC with the digital director connected.
