These signals are not compatible with Pro64 clock inputs. AES3 Clock The clock embedded within AES3 channels 1/2 can also be used as the clock source for the Pro64 network. To set AES3 channels 1/2 as the network clock, use the selector button below the Clock Source LEDs to choose AES In (1/2). The network can extract its reference clock from an AES3 source connected to channels 1/2 even if those channels are not active in the network. The 6416dio does not support the AES3 double speed mode. Sample Rate Pro64 networks can operate at sample rates in three ranges without the use of sample rate converters. The current network sample rate also determines the number of available A-Net Slots. Sample Rate 44. 1/48kHz 88. 2/96kHz 176. 4/192kHz A-Net Slots Available 64 32 16 In an all-analog network, the sample rate can be set at the current Clock Master to the following: · · · · · · 44. 1kHz 48kHz 88. 2kHz 96kHz 176. 4kHz 192kHz When an external clock is used with a Pro64 digital I/O device, the system can lock to any sample rate within the sample rate range that is displayed in the table below. froNt PANel coMPoNeNts 4 Pro64 Series Supported Sample Rates Sample Rate 1x 44. 1/48kHz 2x 88. 2/96kHz 4x 176. 4/192kHz Minimum 39. 7kHz 79. 4kHz 158. 8kHz Maximum 52kHz 104kHz 208kHz When using an external clock source, the Sample Rate display will light the LED that is closest to the sample rate of the external clock source. For example, if an external 48kHz Word Clock source running at the pulledup +4% sample rate in a film/video application is used as the Pro64 network clock, effectively providing the Pro64 network with a 49, 920Hz clock, the front panel 48kHz LED will light solid. Note that no sample rate conversion is required for the Pro64 network to lock to this incoming clock speed variation, guaranteeing pristine audio quality throughout the network. Changing the Sample Rate The network sample rate can be changed only at the Clock Master. Changing the sample rate is done with the selection button found below the Sample Rate LED readout. To choose a new sample rate, press the selection button beneath the sample rate list. Pressing the button selects the next sample rate in the list and immediately starts blinking the new rate's LED and the Enter/Cancel LED; confirmation is required. To exit without changing the sample rate, press CanCEl. 44 froNt PANel coMPoNeNts Pressing the selection button will cycle through the available sample rates. Attempting to change the sample rate on a module that is not the Clock Master will cause the Sample Rate and Clock Master LEDs to flash to indicate the error. Sample Rates and A-Net Slots Changing the network sample rate has a direct effect on the availability of A-Net Slots. For example, setting the sample rate to 96kHz makes only 32 Slots available, numbers 1 through 32. If at the 48kHz sample rate an input module such as the 6416dio is set to the Slot range starting at 33 or 49 and has active channels, these channels will be deactivated when the sample rate changes to 96kHz. These Slot assignments no longer exist in the network. Clock Errors Pro64 can recover from the temporary loss of an external Word Clock or AES3 reference clock when the network is set to sync to an external source. If at any time the external clock source becomes unavailable, the network will temporarily switch to its internal clock, at the standard Pro64 sample rate closest to that which was provided by the external source. When an external clock error occurs, the Network LED in the Clock Source section of the 6416dio interface will light solid. The LED for the external clock source, either Word Clock or AES In (1/2), will flash to indicate that the external clock source has been lost. If the external clock source becomes available again after a failure, its froNt PANel coMPoNeNts 4 associated LED in the Clock Source section of the interface will light solid and the Network LED will go out. Channel Activation Button Each of the sixteen AES3 digital input channels on the 6416dio can be made active on the network individually using the lighted Active button on each channel. (Note that the 6416dio Digital I/O Module accesses its 16 channels in two banks of 8, which are chosen with the Bank Select buttons. ) Activating a channel assigns it to an A-Net Slot in the network, making it part of the network and available to any output module in the network. Channel activation buttons are found below the Link buttons. [. . . ] The example assumes that all modules are set to the same A-Net Slot range. By setting the FOH input module to transmit its A-Net data to Port A and B, the A-Net data flows in two directions. Digital audio arriving at the front of house location from the stage is replaced by the input module at FOH. To send the stage audio to the recording system instead, set the input module at front of house to transmit its data out Port A only. [. . . ]
