Line Output Level calibration The DA8 and DA8P modules feature both hardware level settings and a software fine adjustment to align the Analog Output levels to whatever local/organization operational levels are mandated. On DA8/DA8P cards from run 7 upwards, the hardware level setting is done via software through the option “max output level” in each DA’s setting page, allowing either + 24 dBu or 18 dBu max level. On DA8/DA8P cards prior to run 7 the hardware level setting is in the form of 4 DIP switches per output channel The Hardware settings will usually be set only once, at product installation, and only if the desired Operating Line Level differs from the default ex-factory settings of +18 dBu for 0 dBFS.

IOM-H-PT64 This module allows you to connect your Horus directly to a Pro Tools HD or Pro Tools HDX system through its two Digilink Mini connectors. You can insert up to two modules in a device, meaning you can manage up to 128 Channels at a time. Note that, in Horus, the cards can only be mounted in Slot 3 and Slot 6. Requires Firmware 3.0.5b28137 and above IOM-H-PT64 Key Features • Up to 64 Channels @48kHz per module (32 ch. @ 96kHz, 16 ch. @192kHz) • Up to two IOM-H-PT64 modules in one Horus/Hapi • Automatic Delay Compensation • Three hardware emulation modes (Digidesign 192I/O, HDIO and HDMADI) • Two Digilink mini connectors Ports usage There are two connectors on the IOM-H-PT64 module called Port 1 and Port 2. Working at 44.1/48kHz, both Ports are enabled. Channels I/O 1-32 are carried through Port 1 and channels I/O 33-64 through Port 2. If only 32 channels are needed, it is possible to use only Port 1 or Port 2. With a Sample Rate of 88.2/96kHz, only Port 1 is enabled. All 32 I/O channels will be carried through this Port. If the Sample Rate is set to 176.4/192kHz, then all 16 I/O channels will be carried through Port 1 as well. If both Ports are connected, Port 1 of your IOM-H-PT64 should be connected to Port 1 on the AVID interface and Port 2 should be connected to Port 2. Synchronization and Word Clock When properly configured, a Horus is able to automatically change its internal clock to match a Pro Tools project’s Sample Rate. The proper IOM-H-PT64 module must be selected in the I/O & Sync menu (PT 3 or PT 6 if module is in Slot 3 or 6). The Auto-follow option must be enabled in Setup -> Format menu, and Horus will change its Internal Sample Rate automatically.

In Pro Tools, the Clock source should be set to Internal for the device emulated by the IOM-H-PT64 module (HD MADI in the following example).

Setups with multiple devices Here are a few setups using several Pro Tools Hardware interfaces that need to be synchronized. The other devices present in the setup can be synchronized in several different ways. If two Horus interfaces are used in a setup, they can be synchronized through the Word Clock connectors. To send the actual Sample Rate, the Follow SR option in Setup -> Format must be enabled. IOM-H-PT64 HD Card 1 Pro Tools HD/HDX Clock Source : Horus 1 Internal Sync Source: IOM-H-PT64 WCK Out WCK In Sync Source: WCK IOM-H-PT64 HD Card 2 Horus 1 Horus 2 The next setup is using Horus as the Master clock for all devices. In this case, the Clock Source must be set to the other device’s Word Clock. The Follow SR option in Setup -> Format must be enabled. IOM-H-PT64 HD Card 1 Pro Tools HD/HDX Clock Source : Other device’s WClk In HD Card 2 Sync Source: IOM-H-PT64 WCK Out Additionnal HDLink capable interfaces Horus 1 In the following setup, an external Master Clock is used for all devices. In this case, the external Master Clock controls the Horus Sample Rate. Hence, the external Master Clock must be set accordingly to the Pro Tools project Sample Rate.

IOM-H-PT64 block diagram Output Delay Decoder From Pro Tools Input Delay Encoder To Pro Tools To Horus From Horus Delay compensation Input and Output delay are strongly dependent on the Hardware. This implies that if one records a single source with two different devices at the same time, one will get two slightly out-of-phase tracks. This is explained by the fact that every device has its own circuitry and different components. To minimize this issue, Pro Tools implemented an Auto Delay Compensation feature which will automatically shift the recording depending on the Hardware used. The IOM-H-PT64 module was made to emulate three different Digidesign interfaces and match every interface’s actual input/output latency (within a margin of maximum 3 samples). This chart shows what latency to expect for different setups. Analog/Digital modules latencies are already included in these measures.

Emulation Mode Configures which Digidesign interface the IOM-H-PT64 module will emulate in Pro Tools. This option does not affect the Horus routing or preamps, it will just set the Input/Output Delays as seen above. When set to None, Pro Tools will see the module as an HD MADI, but Horus will use the minimum latency. Therefore, Delay Compensation will not be accurate on Pro Tools in this mode. Error AAE -6116 When Horus is configured to follow the Sample Rate asked by Pro Tools, an AAE -6116 error might happen when opening a project with a new Sample Rate. If it happens, click OK to close the error information. Then, when trying to play the file, the error might show again. After clicking OK, the error should not appear again. If this issue is too frequent, a way to avoid it is to disable the Auto-Follow option in Setup -> Formats and change the Sample Rate on Horus by hand. This should reduce the probability of getting such an error.

Modules: AES Sub-Menu Output Source: Shortcut to the Output Source Routing Page configuration Modules: A/D Sub-Menu Example: Setting a gain alignment of +10dB will make the Horus, Web Access or the Pyramix PreAmps control to be offset by a scaling of +10 dB. Module

Modules: ADA Sub-Menu Mic Alignment: User can offset the Mic Gain Alignment scaling from a Range of 0dB to +12dB. Example: Setting a gain alignment of +10dB will make the Hapi, Web Access or the Pyramix PreAmps control to be offset by a scaling of +10 dB. Max Level Maximum Output Level: +18 dBu or +24 dBu Output attenuation: Calibration of the D/A output (Range -60.0 dB to 0 dB). Refer to the Hardware section for the D/A onboard output level calibration. Roll Off Filter: Sharp roll-off filter: Offers a flat frequency response up to 22kHz, within 0.2dB, which has the tradeoff of 36 samples latency. This mode was and still is the default one. Slow roll-off filter: Offers a low latency of 9 samples, with the tradeoff of a gentle frequency response attenuation starting around 16kHz and reaching - 2.5dB at 22kHz Serial Number: This is the place you can access all your Modules serial numbers without having to unslot them or open the box Type: Module Type description

Modules: PT Sub-Menu Emulation mode: Selection of the Hardware emulated in Pro Tools. Latency is adapted to the mode chosen, see detailed table in IOM-H-PT64 section. None mode is seen as an HD MADI in Pro Tools, but has the lowest latency. Serial Number: Module Serial Number and Run Output Source: Selection of the output source sent to Pro Tools for each of the 8 groups. Any of the digital or analog inputs can be routed to Pro Tools as well as RAVENNA signals. Here is an example of routing: PT 3 (1-8): Routed on PT 3 (1-8) PT 3 (9-16): Routed on PT 3 (9-16) PT 3 (17-24): Routed on A/D 5 (1-8) PT 3 (25-32): Routed on AES 1 (1-8) PT 3 (33-40): Routed on AES 2 (1-8) PT 3 (41-48): Routed on MADI 1 (1-8) PT 3 (49-56): Routed on MADI 1 (9-16) PT 3 (57-64): Routed on RAVENNA

Modules: Loopback (hidden menu, available only for debug use) Transparency Check: This is a Debug Utility tool that verifies the bit transparency of the audio path

Presets Menu (Setup) can be loaded (one at a time) Auto Save: If enabled the save configuration will happen at every 2 minutes.

System (Setup): The Dark option will display a black Screen Saver, mainly used when Horus needs to be a discreet stage box. Terminations: 75Ω for WCK: Sets 75Ω termination for the Wordclock Input. 75Ω for Video: Sets 75Ω termination for the Video reference Input. Unless the Video Reference signal provided to the Horus is daisy-chained to other equipment, you should always terminate your Video signal for most reliable operation.
