Installation

Dimensions

Mounting
The Axon DTH1620 can be mounted in any orientation with a flat surface that meets the dimensional requirements described under “Dimensions” on page 5, is not exposed to rain, condensing humidity, excessive heat or cold, and is strong enough to hold the amplifier, weighing 2 lb, 6 oz, during the intended operational scenarios and shall not block any ventilation holes. In addition, the mounting location must have enough space to allow cable connections without stressing the connections,

1. Use the dimensions to locate and mark four spots on the mounting surface.
2.  If necessary, drill four holes at the marked spots. The drill must be smaller than 0.177 in ches (4.49 mm). and the appropriate size for the selected mounting hardware.
3.  Use appropriate hardware for the mounting-surface material to secure the amplifier in the selected location.
4. Connect and secure the cables to allow for appropriate stress relief.

Selecting a Power Supply for Your Installation

The DTH1620 amplifier draws about 15 W when idle. For operational head room, use 20 W as the idle power. When all channels have equal power, a safe formula for computing the required current capability of the power supply is: Is = ((PcNcEff)+Pi)/Vs
Where:

• Is = Required power supply current capability

• Pc = Power per channel (maximum of 20 W per channel) Nc = Number of channels (maximum of 16)

• Eff = Efficiency factor = 1.25 (80%)

• Pi = Idle power of amplifier (20 W)

• Vs = Supply voltage (24 VDC)
  Example: We want all 16 channels to be simultaneously 5W capable.

• Is = ((5 W 16 channels 1.25 efficient factor) + 20W ) / 24V

• Is = ((5161.25)+20)/24

• Is = 5A
  If all channels have different power output requirements then simply add the output power for all channels.

• Is = ((Sp * Eff ) + Pi ) / Vs

• Sp = Sum of Power for all channels i.e. (P1 + P2 + P3 + … P16)

Axon DTH1620 Command Protocol

The DTH1620 uses DHCP by default to obtain an IP address. A static IP addres can be set using the Dante Controller. UDP port 49494 is used for sending the command.
The following commands are available for the DTH1620. Version 1.2
DTH1620 Command Set

Identify Device / Find Unit:
The intended use of these commands is to locate a device by flashing the device’s non-fault LED’s. When the Identify Device command is sent, with the mode set to on (ID 1), the non-fault LEDs flash on and off until another Identify Device command is sent with the mode set to off (ID 0), or the device is reset or power cycled.
The Find Unit command flashes the non-fault LEDs for five seconds then automatically turn off.

Description of Command| Example Command| Example Response| Description of Response
---|---|---|---
Identify Device (ON)| ID 1| ACK ID 1| Identify Device mode active
Identify Device (OFF)| ID 0| ACK ID 0| Identify Device mode inactive
Flash Identify LED for 5 seconds| FU| ACK FU| Find Unit mode activated.

Version / Bootloader Version:
The VERSION command returns the firmware version of the device. BVERSION will return the version of the bootloader.

Description of Command| Example Command| Example Response| Description of Response
---|---|---|---
Recall firmware version| VERSION| ACK VERSION 1.0| Firmware version is 1.0

Defaults
The DEFAULTS command forces the system to return to factory settings:

•  Headphone limit is set to 0 dB.
•  Master and Channel volumes are set to 0 dB.•
• Master and Output mutes are disabled (unmuted).
•  All subscribed Dante streams are unsubscribed (no streams selected)
•  If a static IP had been selected, it is reset and DHCP is re-enabled.

Get/Set Headphone Limit:
“Headphone Interface – J2” on page 2
This set of commands gets and sets the headphone volume limit. Valid settings are -103 dB to 24 dB. The headphone volume is optionally controlled by a 10 kΩ potentiometer connected between pins 2 and 6 of connector J2. This command sets the upper limit of the volume setting and can be used to adjust for the maximum volume for a given style of headset.

Description of Command| Example Command| Example Response| Description of Response
---|---|---|---
Get the headphone volume limit| GHPLIMIT| ACK GHPLIMIT 0| Headphone is currently limited to 0 dB max.

Unmute output channels 1..4, mute output channels 5..16| SOM 0 0xFFF0| ACK SOM 0 0xFFF0|

Get/Set Output Master Mute:
This set of commands gets and sets the output master mute status. The master mute mutes all channels simultaneously. Clearing Master Mute will only clear the master mute state; it will not clear an individual channel’s mute state.

Description of Command| Example Command| Example Response| Description of Response
---|---|---|---
Get Master Mute setting| GOMM| ACK GOMM ON|
Set Master Mute| SOMM 0| ACK SOMM 0|

Get/Set Output Volume
This set of commands gets and sets the volumes for each output channel (parameter 1 is 1…16) or for all output channels (parameter 1 is 0) range is +24 dB to -103 dB. The total output volume is a combination of the individual channel and Master volume up to the 20W maximum for the channel.

The data shall be placed such that array index 0 is channel 1 for all channel data.
The entire structure is 38 bytes.

Get Metering Data
This command gets all metering data for all Dante channels. The response contains 64 hexadecimal formatted values.

•  Values 1 through 16 represent metering levels for Dante RX channels 1 through 16.

•  Values 17 through 64 are placeholder values of 0xFD, representing invalid channels. The metering values are the following:

•  0x00 = Clip

•  0x01 = 0 dB

• …
  0xFD = -126 dB or invalid channel

•  0xFE = Mute
  Values between 0x01 (0 dB) and 0xFD (-126 dB) represent increments of -0.5 dB.

Note: that these values are from Brooklyn II and represent metering from the Dante perspective. For example, a value of 0xFE (Mute) indicates that the corresponding Dante channel is muted on the Brooklyn II. This does not reflect the Amplifier’s Master or per channel mute state.
