Field name

Meaning

General

ID

The two octets of the amplifier ID number in hex format. This is shown on the display at the back of the unit.

IP Address

The IP address of the amplifier. This is shown on the display at the back of the unit.

Power

Lit (green) when the amplifier is switched on.

If remote mode is selected on the amplifier, you can switch it on or off using the Power button within NWare.

Rmte (Remote)

Lit (green) when the amplifier is running in remote mode.

Link

Lit (green) when a link is established between NWare and the device across the network.

Fault

Lit (red) when a fault condition, e.g. thermal or short circuit, has been detected by the amplifier.

Please refer to the amplifier documentation for information on fault conditions.

CobraNet

Input (A / D)

Selects either analog audio input using Phoenix connectors or digital audio input from the CobraNet network.

Bundle Num.

The audio bundle number for the device. This must correspond with the bundle number specified for the NION associated with the amplifier. You can then make connections to the amplifier using the NION flyoffs.

Channel x

Fault

Lit (red) if the amplifier enters ACL or IGM or experiences a thermal, DC voltage, or short circuit fault.

Name

A name for the channel. This label can be used to improve the clarity of the user interface for the end user.

Gain

Adjusts the amount of amplification or attenuation to be applied to the channel. Range is -97 to 0 dB.

Mute

Mutes the channel output. The LED is lit (red) when the channel is muted.

Alerts

User Temp

The user-specified upper limit for the channels' heat sink temperature. If the limit is exceeded, the light will be lit (yellow).

IGM

Lit (yellow) when the Instantaneous Gain Modulation (IGM) circuit detects a load that overstresses the output stage. The channel gain is automatically adjusted to a safe level.

ACL

Lit (yellow) when the Active Clip Limiting (ACL) circuit is active because a channel has reached the clipping point.

Cobranet

Subchannel

The subchannel numbers for the audio channels.

Faults

Temperature

Lit (red) when a channel’s heat sink temperature reaches 75°C (which may indicate an obstructed air supply). The channel will independently protect itself by disconnecting its load and shutting down until it has cooled.

DC

Lit (red) when the amplifier channel detects DC voltage or subsonic frequencies at a channel output. The respective output relay will immediately open to prevent loudspeaker damage.

RTLM
(Real Time Load Monitoring)

Lit (red) when the load for the channel exceeds the upper or lower limit. If this indicator is lit, and the RTLM training process has successfully completed, it indicates that the load on the amplifier has altered significantly. This could be because a loud speaker has blown, for example.

RTLM

Upper

The upper limit for the load level. If the limit is exceeded, the Fault light will be lit.

Lower

The lower limit for the load level. If the limit is exceeded, the Fault light will be lit.

Advanced

Field name

Meaning

Subnet Mask

The subnet mask for the Ethernet / CobraNet network.

Gateway

The IP address of the router.

If there is no router, this will be set to 0.0.0.0.

Gain/Sensitivity

Position of the Gain switch at the rear of the amplifier.

This can be set to give constant sensitivity, or a constant gain of x20 (26 dB) or x40 (32 dB).

Display only.

Version

Firmware version running on the amplifier.

AC Power Info

Volt

Voltage provided to the amplifier.

Amp

Current provided to the amplifier.

Display only.

Watt

Input power provided to the amplifier.

Display only.

RTLM

Channel

The channel number.

Train

Starts the training process for a channel. Used once speakers have been connected to the outputs and audio is running through the amplifier. The process takes between 5 and 10 minutes. The Training light will switch off automatically when the process is complete.

Notes:

  • If the load level is too low, the training process will not complete.
  • If you are using a Ci amplifier, the training process will not complete successfully unless all the channels are loaded and driven appropriately.

 

Abort

Aborts the training process for a channel. Use this button to stop the training process if more than 10 minutes have elapsed since the process was started, and the Training light is still lit.
