  • Page 3: Introduction

    For your safety, please read the Important safety instructions and the Precautions section before installing and operating the amplifier. The “engine” behind every Alcons sound system is the Amplified Loudspeaker Controller. The ALC is a combination of a loudspeaker controller and a very high efficiency power amplifier.
  • Page 4 Remote-control The Director seamlessly integrates in ALControl™; Alcons Audio’s proprietary, Ethernet-based ALC network . ALControl™ can control individual or clusters of Sentinels and Directors together, with functions like grouped EQ’ing, event and (on-line) system monitoring and repairs, firmware uploads, a.o.

    3. Precautions Save the packing material. Should you ever need to ship the amplifier, use only the original packing. Read this manual carefully before installing and operating your amplifier. Retain this documentation for future reference. Always operate the amplifier with a grounded AC mains supply. Ensure that the quality of the mains supply is good enough and that it can supply the required peak currents.

  • Page 7: Installation

    Unpacking Carefully open the shipping carton and inspect the amplifier. Every Alcons amplifier is thoroughly tested and inspected before leaving the factory and should arrive in perfect condition. If you find any damage, notify the shipping company immediately. Only you, the consignee, may initiate a claim for shipping damage. Be sure to save all packing materials for the carrier’s inspection.
  • Page 8 4.Installation Mounting The ALC Director amplifiers mount in standard 19-inch installation racks. A rear mounting set gives additional support. Rear support is highly recommended in all applications. ALC Directors can be stacked directly on top of each other. There is no need for spacing between units. Ensure that the bottom ALC Director has a bottom support over the entire depth.

  • Page 10 5.Overview Rear panel The Director is primarily aided for the installation market and it features installation specific standard terminal block type connectors from Phoenix. All cable counterpart connectors are included. 1) Airflow exhaust Do not block this area, because this will reduce the airflow. 2) Networked Audio Inputs 2,1 Connect two RJ-45 connectors and leads for the networked audio inputs.
  • Page 11 7) Outputs 1-8 Four 8-pole terminal connectors are installed to connect your loudspeakers to the amplifier channel 1 to 8. Each terminal connects two speaker outputs. It features SIS Compatible wiring and is backward compatible with all existing SIS Signal Integrity Sensing wired loudspeakers from Alcons.

Blue Normal operation Blue blinking EQ or delay settings changed – with changing settings in the equalizer or delay section, the encoder will blink, indicating that changes have been made to the stored settings.
  • Page 18 7.Operation Display menu The Director6 has a simple yet effective user interface using the display as user interface together with 8 channel buttons and the encoder. In each menu, the channel button functionality differs and their colours change in a way most usable in that specific menu. Menu overview The menu overview consists of a list with all the menu-items.
  • Page 19 7.Operation Menu-items Overview This menu gives an overview showing all channel and their real-time audio signals, input and output. The buttons function as signal detect indicators, changing it illuminated colour according to the input level (from green to orange to red). This menu is just for showing an overview, no settings can be configured here. Gain Use the channel buttons to directly select the channel or scroll to the channel using the encoder and press it.
  • Page 20 7.Operation Mute Use the channel buttons to directly mute/unmute the channel or scroll to the channel using the encoder and press it to mute/unmute the channel. Channel buttons are illuminated red when the corresponding channel is muted. Scrolling through the channels with the encoder shows the frequency plot of the equalizers set up in the selected channel and if it is on or off. Selecting a channel opens up the submenu where each of the 8 band EQ’s can be configured and turned on/off.
  • Page 21 7.Operation Delay Use the channel buttons to directly set the channel delay or scroll to the channel using the encoder and press it to set the channel delay. In the submenu, the delay can be set in milliseconds or in meters. Also the delay can be switch on/off an the step-size of the delay increments can be set to coarse or fine.
  • Page 22 7.Operation Routing The routing menu show a overview with each channel and its routed inputs. Selecting a channel opens up the submenu where the input signal may be selected. Use the channel buttons to quickly enable/disable each input signal. Digital or analog input may be selected and also bridge mode can be enabled here. Polarity Use the channel buttons to directly set the channel polarity or scroll to the channel using the encoder and press it to set the channel polarity.
  • Page 23 7.Operation Projects Scroll through the menu items to store a project from a usb drive or recall or remove a project from the local drive. When storing a project from a usb drive to the local drive, make sure to first connect a usb drive to the usb port next to the display. Oplog This menu shows the oplog, a list with all timestamped status updates.
  • Page 24 7.Operation Setup The setup menu consists of the following items: -audio fallback, used to configure aes fallback to analog and to individually arm each channel. -aes gain trim, used to trim the gain a certain amount of dB to equal the aes levels with analog levels. ALC Director User’s Manual.
  • Page 25 -network, this menu shows the MAC-address and the current IP-address of the Director. Automatic IP-address assignment (DHCP) as well as static IP-address assignment may be selected. Also the Alcons logo can be set to blink, this is mainly useful in an application with multiple Directors.
  • Page 26 -ALControl name, this menu lets you set a name for the Director and is visible in ALControl when it discovers the Director. -firmware, this menu allows you to update either the front firmware, dsp firmware or the preset library with all Alcons speaker presets. It is advised to regularly check for updates (introducing possible bugfixes, adding new features etcetera).

    8. Installing Director ALC with Sentinel ALC When installing the Director in combination with a Sentinel amplified loudspeaker controller, a number of precautions have to be taken into account: A) Due to the different design of the Director compared to the Sentinel, the air flows of the cooling systems differ: -Sentinel: has a back-to-front airflow -Director: has a front-to-back airflow It is advised not to mount the Director in the same rack as the Sentinel!
