Mixer On/Off

This switch turns the internal mixer On or Off. When the Mic or Line/CD inputs are used, this switch must be set to the On position. If these inputs are not being used, the mixer should be turned Off. This will help prevent the mixer from loading the Link, or the Internal Mixer, and contributing noise to the system. The internal mixer should not be used when a source other than another nx520p or similar cabinet is connected to the LINK jacks. Remember, a maximum of three mixers, in a chain of cabinets, should be used! A much larger number of cabinets may be used with the nx520p mixers disabled on the additional cabinets.

Mic control

This control adjusts the volume level the Mic input. The microphone signal output to other cabinets through the link connections will be affected as well.

Line/CD control

This control adjusts the volume level of devices plugged into the Line/CD input. The signal out to other cabinets, from this device, through the link connections will be affected as well. A line-level signal and microphones can be connected simulataneously.

Treble and Bass controls

These controls affect the signals from devices plugged into the Line/CD and Mic inputs. The signal out, to other cabinets, through the Link will also be affected. These controls do not affect signals coming into the cabinet from the Link connections.

Green PWR LED

Illumination indicates that AC power is on and the fuse is functioning.

Yellow Limit LED

This indicates that the cabinet is operating at full power and the limiter(s) are actively reducing the signal level. It’s all right to operate in limiting as long as the clip light is not constantly on. The Limit light does not indicate low frequency processing action. There are separate limiters for the woofer and horn. This LED will indicate operation of either limiter.

Red Clip LED

The illumination of this LED indicates that the signal level is excessive and may cause distortion. Reduce mixer levels or turn down the Level control (on nx520p) to reduce clipping.

POWER switch

This turns the power On and Off to the cabinet. Note; a cabinet that is turned off, but is one of the cabinets in a chain might cause hum (or buzz) in the other cabinets.

Fuse

The mains fuse should never blow even in extreme operating conditions. A blown fuse will generally mean that excessive mains voltage has been applied or there’s a serious fault with the unit. Self re-setting thermal switches are built into the power transformer as well as on the internal heat sink. These will not trip even under the most extreme operating conditions and are provided only for safety reasons. Thermal margins may be compromised when operating facing straight up, straight down or while operating in direct sunlight!

A note about unbalanced operation: When connecting an unbalanced source (such as a mixer with RCA outputs) to balanced inputs such as an nx520p, the best hum rejection can be achieved by running a balanced connection right to the unbalanced plug. The return connection should be connected to ground at the unbalanced plug. The nx520p does not connect the AC power ground directly to the input signal ground. This will eliminate most ground problems.
