Introduction The DaySequerra DownMix enables 5.1 surround sound to be transported through any stereo infrastructure using the DTS Neural Audio process. Because DownMix renders sound independently of the transport environment, it will compliment analog, digital, linear or compressed mediums. The process is based upon the principle that both natural stereo and 5.1 content are two dimensional; both contain width and depth spatial attributes.
Typical Applications Here are some examples that describe some typical applications where you might use DownMix. FM Radio Production Studio A typical application of DownMix is to create a watermarked stereo signal from multi-channel original content originating from a computer with a multi-channel sound card, Stereo Automation or Storage System, or direct from your Digital Production Console.
Installation Immediately upon receiving your DownMix, please make a careful inspection for any shipping damage. If damage is found or suspected, please notify the carrier at once and then contact your dealer. DownMix is shipped in one carton, which contains: the DownMix unit, two AC power cables and this Users Manual. We strongly encourage you to save the shipping carton and shipping materials supplied with your DownMix.
Front Panel Bargraph Meters INPUT LEVELS - Six 10-segment multi-colored LED meters display the audio level for each channel of the inbound audio stream. OUTPUT LEVELS - Six 10-segment multi-colored LED meters display the audio level for each channel of the down mixed audio stream. Status Indicators AES LOCK - Green LED indicator illuminates when DownMix has acquired a valid AES3 digital input signal.
Rear Panel AES INPUTS - Four 75Ω BNC connectors will accept an AES3 digital audio stream. AES OUTPUTS - Three 75Ω BNC connectors output the down mixed AES3 digital audio stream. AES SYNC - Two 75Ω BNC connectors that allow DownMix to receive an AES REF or DARS clock signal from an external source and pass it on to other devices. The AES-3id-1995/SMPTE 276M standard dictates a 75Ω unbalanced connection and requires proper termination.
Input 1: Voltage detected on this input will cause DownMix to go into pass-though operating mode. Input 2: Voltage detected on this input will have DownMix take the input audio signal and downmix into Lt/Rt. Input 3: Unused at this time. Input 4: Unused at this time. NETWORK - Used to update DownMix’s firmware. To connect directly to a PC without use of a network switch or hub, a crossover cable is required. Firmware updating is accomplished via UDP Port 44600.
Meter Display Figure 1. Metering display DownMix. INPUT LEVELS – LED display shows current amplitude of input signal from -60dB to 0dB across all active channels. Unused channels will not light the display. L - Left (AES Input 1) R - Right (AES Input 2) C - Center (AES Input 3) LFE- Low Frequency (AES Input 4) Ls - Left Surround (AES Input 5) Rs – Right Surround (AES Input 6) OUTPUT LEVELS – LED display shows current amplitude of signal generated by DownMix across all active channels.
Home Screen Figure 2. Home Screen on DownMix. DownMix has been designed with ease of use in mind. Most of the common settings are available for modification right on the home screen. While the unit is at this screen, press the HOME key to invoke home screen selection mode; a selection box will appear. Turn the rotary encoder to move the box to the desired field to be changed and press the ENTER key to modify the value. Rotating the encoder again will cycle through the available options.
Programming Menu If AC line power is lost or momentarily interrupted, DownMix will revert to its previous state. To enter the programming menu, turn the rotary encoder in any direction while at the HOME screen. The ENTER key will enter the currently selected sub menu or enter the value mode for the selected option. A press of the BACK key will navigate to the previous menu level or revert the current value to its last stored state. Menu Tree Figure 3. Visual Map of DownMix Menu System.
Menu Functions and Descriptions While at the home screen, and not in home screen selection mode, rotate the encoder in any direction to enter the menu. From this screen you may navigate to the rest of the menu by selecting SYSTEM MENU. Also displayed are keylock controls and channel audio adjustments. Selecting KEYLOCK from this menu will lock the front panel controls of the unit immediately.
Network Menu DownMix has several configurable network settings. All of the DownMix network settings are password protected. The password to change the network settings is dnmix123. Please take note when entering the password that the DownMix password is case sensitive. DownMix is configured to take a DHCP address by default. Device Name: Allows you to change DownMix’s name as reported to DNS. Press ENTER while the cursor is over this field to go into data entry mode.
Alarms Menu All alarms are disabled by default at the factory. To take advantage of this function, the desired settings need to be enabled. AES Lock: Allows the AES Lock alarm to be suppressed. PSU Alarm: Allows the Power Supply alarm to be suppressed. About Menu Model Number: Displays the model number of the unit. Serial Number: Displays the serial number of this unit. Hardware Rev: Displays the hardware revision level of this unit.
