• MacOS & Windows supported.
• A standard network connection (ethernet) is required.
• Direct connection through: Router; Switch (managed or unmanaged); USB‑to‑Ethernet adapter.
• Hubs/docks with restricted network access may not work reliably (e.g., Microsoft Docking Stations, OWC Thunderbolt Docks).

• NETGEAR GS308E (proven highly stable).
• TP-Link UE300 USB‑to‑Ethernet Adapter (fully compatible, proven highly stable).

Managed or unmanaged?

• Both options work, as long as IGMP Snooping and VLAN‑Management are not configured with restrictions.
• For simple setups we recommend unmanaged switches.

• Speaker(s) and computer must be on the same network.
• DHCP is recommended for automatic addressing.
• Static IP can be used in advanced studio installations.
• WiFi should not cause issues and has proven to be stable, but for the most reliable performance we still recommend ethernet connections whenever possible.

Can I have multiple devices on the same switch?

Yes, other audio hardware that uses network remotes (such as RME AVB/MILAN converters, Eventide H9000 and more) can also run on the same switch.

Important:

• Network traffic must remain cleanly separated.
• Avoid overloading the switch, especially with cheaper models.

To use all functions in CTRL, a firmware update of each connected MK2 or BASS unit may be required.

If you see an exclamation mark (!) next to a device that means a firmware update available and can be downloaded via the update option in the CTRL top menu.

After a successful update:

• Reboot speaker.
• CTRL will reconnect automatically.

LED colours:

• Green → On (Active)
• White → Standby

CTRL may not find devices that are in deep sleep mode.

• Device discovery
• Group creation & management
• PEQ
• Phase Linearizer control
• Input configuration
• Preset export & import
• Closed & Ported operation for MK2 and BASS models

Important: Once a preset is uploaded to the speaker, it remains stored in the DSP. The network connection is no longer required afterwards.

• Switching between Closed and Ported mode does not add latency when the Lineariser is off.
• With the Lineariser active, different FIR filters are used for Closed vs. Ported modes.
• Latency may change slightly: typically 1–3 ms.

• All tuning parameters on Mk2 models—including CoP—are implemented entirely in DSP.
• The analog signal path remains unchanged.
• No relays or analog components are switched.
• CTRL exposes additional parameters not available on the physical back panel.

Settings from CTRL are stored permanently only when using: Upload to Device or Upload to All Devices.

If you do not select either of these options, changes are not stored and will be lost after standby or power cycling.

Stored settings are recalled when the Lineariser knob is set to the "*" position. Any other knob position returns the speaker to hardware‑controlled behaviour.

The rear controls are automatically deactivated in two cases:

1. When the speaker is connected via RJ45 and actively controlled by CTRL.
2. When the Lineariser knob is set to “*”, recalling the last uploaded CTRL configuration.

There is no global “off” state for the hardware controls, but these two states give full control to the software.

• PEQ currently cannot import REW correction profiles.
• This feature is being evaluated, but is currently not available.

• When adjusting a parameter at the group level, the value is written to all devices in the group.
• You can still edit devices individually afterwards.
• If you later change that parameter again at the group level, the group value will overwrite all individual values.
