2 Installation Requirements

2.1 Electrical and Wiring

The AQZ32 features a universal power supply compatible with 100-240VAC, 50-60Hz. Always use the supplied power cord and do not remove the AC ground connection. Use high-quality shielded cable for input signals and balanced inputs whenever possible. To prevent system noise or oscillation, avoid running low-level signal wires parallel to speaker outputs or AC wiring, especially over long distances. Double-check all connections and settings before testing. Refer to the specifications section for details on input, output, Ethernet, and other properties.

2.2 Mechanical

The AQZ32 is a 1RU unit designed for standard 19-inch equipment racks. Use four screws for mounting to the front rack rails.

2.3 Network Requirements

The AQZ32 supports 100MB or 1GB Ethernet; GB Ethernet is recommended for Dante. Use the Primary Ethernet jack for AquaControl and Dante audio streams. The Secondary Ethernet jack is for redundant Dante signal connections only and must be wired to a different router or switch. A solid green LED on the Ethernet jack indicates a successful network link; a yellow LED indicates a 1GB network connection. Refer to section 5 for network discovery instructions.

2.4 Dante Requirements

Connecting to other Dante-equipped devices requires Dante Controller, a free software download from Audinate. See section 8 for Dante usage details.

2.5 Browser and Resolution

Supported browsers include Chrome, Edge, and Safari. Ashly AquaControl software requires a minimum screen resolution of 1024x768 and a screen size of 10 inches or larger for optimal experience.

3 Front Panel Features

3.1 Mounting Holes

For rack mounting. Always use all four mounting holes.

3.2 Power LED

The AQZ32 lacks a power switch. Power can only be turned off via the software's Power On/Off button in the "Settings > Panels" page or by disconnecting AC power.

3.3 COM LED

Indicates network communication activity. It also lights up for 10 seconds when the "Identify Device" function is selected in "Settings > Network".

3.4 Pairing Status LED

Reserved for future use.

3.5 Input Status LEDs

These LEDs sample the audio signal after the analog input preamp gain stage but before the input signal chain DSP. They illuminate green for signal present (-20 dBu), amber at +10 dBu, and red at maximum level (+20 dBu). Red also indicates a muted input channel.

3.6 Output Status LEDs

These LEDs are post-DSP. They illuminate green for signal present (-20 dBu), amber at +10 dBu, and red at maximum level. Red also indicates a muted output channel. These LEDs also display progress during admin or factory resets.

4 Rear Panel Features

4.1 Balanced Mic/Line Inputs 1-16

Use Euroblock connectors for 3-wire balanced inputs (+, -, G). For unbalanced signals, connect the hot signal to (+) and ground to (-), leaving the AQZ32 input ground pin unconnected. Maximum input level is +21 dBu.

4.2 Device Reset Switch

Two reset levels are available: Admin and Factory Default. The reset level is determined by the duration the switch is pressed during a cold boot. A cold boot involves removing AC power, then reapplying it while holding the reset switch. Input LEDs 1-16 will illuminate sequentially, followed by output LEDs 1-16. Releasing the switch during this sequence initiates the reset.

• Admin Reset: Restores the admin password to "secret" but preserves other user credentials, presets, and settings. It also resets IP configuration to Automatic (DHCP/Link Local). Release the switch after all 16 Input LEDs illuminate but before all 16 Output LEDs illuminate.
• Factory Default Reset: Deletes all user IDs, passwords, presets, and events, restoring all settings to factory defaults. Release the switch within three seconds after all 16 Output LEDs illuminate. Holding the switch longer than three seconds cancels the reset.

4.3 Balanced Line Outputs 1-16

These outputs provide post-DSP analog signals. They are pseudo-balanced (single-ended signal with balanced impedance). Maximum output level is +21 dBu.

4.4 VCA Remote Level Controls 1-8

VCA (voltage controlled amplifier) inputs allow remote control of VCA gain blocks added to the DSP signal chain. Ashly WR-1, WR-1.1, and WR-1.5 remotes, or a custom potentiometer circuit, can be wired to these inputs. See section 7 for examples.

4.5a Trigger Inputs 1-8

Eight contact closure pins can trigger user-defined events or sequences. See section 6.4 for a list of available events.

4.5b GPO Outputs 1 & 2

Two logic outputs, referenced to the ground pin on the same connector. Logic output changes can be driven by presets, triggers, or scheduled events.

4.6 Ethernet Port

The primary Ethernet jack connects to the network for AquaControl and Dante. The secondary Ethernet jack is for redundant Dante connections only.

4.7 MAC Address

The device MAC address is located on a sticker on the back panel and is also accessible in AquaControl's Settings > Network page.

4.8 AC Inlet

Connects to the detachable AC power cord. Use only the factory-supplied cord. Do not remove the AC mains ground connection.

5 Network Discovery

Ashly AquaControl devices feature a built-in web server, allowing access via a web browser on computers or mobile devices. Connection can be made through an Ethernet/Wi-Fi router or a direct Ethernet connection to a PC. Supported browsers include Chrome, Edge, and Safari. A minimum screen resolution of 1024x768 and a 10-inch screen size are recommended.

Ethernet Connection

AquaControl devices default to automatic IP assignment (DHCP or Link Local). Connect the primary Ethernet jack to a network router or directly to a PC. The secondary Ethernet jack is not used for AquaControl. Once connected, AquaControl can be accessed to change the connection to a static IP if desired.
