Hardware Settings & Multiple Devices
Horizon 8P Hardware Settings.
Horizon 8P Monitor Settings.
Use Hardware Settings when you need to configure the Horizon system itself — connected devices, clocking, sample rate, analogue reference levels, digital mode and routing. Monitor Settings is kept alongside it for settings that affect the active monitoring path.
Using more than one Horizon
Horizon Control can manage up to four connected Horizon devices. Connect the first unit to the host computer over Thunderbolt, then continue the chain from the second Thunderbolt port of that device to the next Horizon as required. A system of four Horizon 32 units provides up to 200 × 200 I/O channels.
Thunderbolt is only the host connection between the units. A multi-Horizon system also needs a separate BNC word-clock connection so every device shares the same timing reference. The Primary Horizon uses its internal clock for the Horizon chain and the secondary units receive word clock from it. Keep the complete digital system to a single clock master.
A separate BNC word clock cable is required when daisy chaining multiple Horizon devices.
Once the hardware and BNC clock connections are in place, add the connected units to Horizon Control from Hardware Settings. If several identical Horizon devices are connected, use Identify to confirm which physical unit you are adding.
Add New Device window.
Open Hardware Settings and select Add Device, then choose the connected Horizon units you want to add from Available Devices. Select Save and give each unit a useful name, or keep the default product name. Once added, the devices appear together in Horizon Control and their I/O becomes available to the Horizon Control Mixer and Routing Matrix.
Removing a device from Horizon Control does not erase its previous configuration. If the same Horizon is connected and added again later, the host system recalls that configuration.
Choosing the Primary Horizon
One connected Horizon is always the Primary device. The Primary controls the active monitoring system, supplies the Monitor Controller view and makes its Monitor Controller Speaker Layout sources available in the Routing Matrix. Only one connected Horizon can provide the active monitoring system at a time.
In Horizon Control, open Hardware Settings > Add Device. Add the Horizon you want to use for monitoring first; this becomes the Primary device. Then add any additional Horizon devices. To change the Primary device, remove the devices from Horizon Control and add them again, starting with the new Primary.
The host system retains the previous monitoring configuration associated with each Horizon, so making a device Primary again recalls that configuration.
When using multiple Horizon devices, connect the Primary device's BNC word-clock output to the next device's word-clock input. Continue the BNC chain in the same order shown in Horizon Control. If the device order changes, update the BNC connections to match. If a device shows a yellow clock status, check its word-clock connections and clock settings.
The device order shown in Hardware Settings is also reflected by the Mixer Fast Scroll Bar, making useful device names especially helpful in a larger system. The Fast Scroll Bar is hidden when only one Horizon device is connected. In cascaded systems it becomes available for quicker navigation through the channel list.
System and device settings
Hardware Settings contains both system-wide controls and settings for the selected Horizon device.
Global settings
- Clock Source — choose Internal when Horizon is the timing master, Digital 1 or Digital 2 when Horizon follows the incoming digital signal on that optical bank, or External (Word Clock) when the system follows a separate BNC word-clock source. In a multi-Horizon chain, secondary units still require BNC word clock from the Primary device.
- Sample Rate — 44.1, 48, 88.2, 96, 176.4 or 192 kHz. Keep the DAW and other connected digital equipment at the same sample rate.
- Sleep Timeout — Never, 5 minutes, 15 minutes, 30 minutes, 1 hour or 2 hours. This setting applies across the Horizon chain.
Horizon 8P analogue reference levels
Use the input and output reference-level settings when Horizon 8P needs to match the operating level of the analogue equipment around it.
Inputs 1–8 can be set to +18 dB or +24 dB whether the channel is using its Mic/Line connection or D-sub return.
The output reference level can also be set to +18 dB or +24 dB for the D-sub line outputs 1–8, Main monitor outputs 9–10 and additional TRS line outputs 11–12. These analogue reference levels are separate from the calibrated monitor Reference Level in Monitor Settings.
Digital mode
Choose ADAT or S/PDIF for the selected Horizon 8P according to the optical equipment connected to it. Horizon Control updates the available digital channels and the Routing Matrix to follow the selected mode; in S/PDIF mode the two-channel digital path is shown.
Function assignment
The Horizon 8P Function button can also be assigned from Hardware Settings. The assignment is shared with the hardware, so changing it in Horizon Control updates the function available from the front panel.
Word Clock Termination
Enable 75 Ω Word Clock Termination when Horizon 8P is the final or only device receiving BNC word clock in a chain. Leave termination disabled when the clock connection continues to another receiving device.
Monitor Settings
Monitor Settings applies to the Primary Horizon device and controls how the monitor path behaves rather than how the analogue I/O is referenced.
- Dim Amount — sets the Dim reduction from −12 dB to 0 dB. The default is −10 dB.
- Reference Level — sets the calibrated monitor listening level for use with the assignable Function control.
- Volume Recall — when enabled, restores the previous monitor volume after power-up.
- Talkback — uses Horizon's built-in talkback microphone.
- Mono Mode — choose Left, Centre or Right for mono monitoring.
- Speaker Layouts — view, edit, rename or delete the layouts associated with the Primary Horizon device. Horizon Control can save up to six layouts.
