1.Operation

The NX55P is a bi-amped powered full-range loudspeaker with a built-in two channel mixer. Multiple NX55P cabinets may be connected through the Link option. If you’re using the NX55P with an external mixer, the internal mixer can be disabled. The built-in mixer has a micro- phone input and two (combined) ¼ inch inputs for line sources such as CD players. Advanced signal processing is used to give maximum performance at all levels. There’s a switch to provide a low frequency rolloff if you’re going to use the NX55P with a subwoofer.

2. Mic Input

Any regular microphone can be inserted into the Mic input. Phantom power is built–in for condenser microphones.

3. Line/CD inputs

The Line/CD inputs allow line-level sources such as CD players, cassette decks or any other sources such as mixers to be connected. If more than one input is used these inputs blend the signals (e.g. stereo sources) into mono. The inputs are balanced to help reject hum (when used with balanced cables) Unbalanced 1/4-inch plugs can be used. When connect- ing to unbalanced sources using balanced T.R.S. cables does help reduce unwanted noise and/or hum. These inputs can be used for lower-level Line inputs, which need a bit more gain (as opposed to using the Link jacks, which have no control). These inputs allow you to have a greater range of level adjustment than using just the NX55P Level control (e.g. if an in- dividual cabinet, in the chain needs to operate at lower level than the rest).

4. Link

These parallel jacks allow multiple NX55P cabi- nets to be connected together. The Link Jacks are the correct input to use when driving the NX55P from an external mixer. The Link Jacks op- erate at line level (+4 dBv) to achieve full power. The NX55P Level control allows operation at levels from –2 dBv to +10 dBv for full power. When operating from signals that are not as strong, use the Line inputs of the first cabinet in the chain. The Link jacks are high quality balanced inputs with very good common mode (hum) rejection. To ensure maximum hum rejection, the proper balanced cables must be used. When con- necting to unbalanced sources using balanced T.R.S. cables does help reduce unwanted noise and/or hum. Jacks marked LINK OUTPUT are con- nected in parallel with the LINK INPUTS and are provided for convenience to connect down- stream cabinets. Link inputs may also be used as outputs and link outputs may be used as inputs.

5. Level Control

This control allows the audio level of the cabinets, linked in a chain, to be individually adjusted. This control does not adjust the level of the Link jacks. The Level control should be set at '0' (center) for most applications.

6. LF Rolloff

For operation with a subwoofer, the LF Rolloff switch shuts off the low frequency boost and filters out signals below 100 Hz. It’s not neces- sary to use this switch for speech applications because the Mic input already has a high pass filter. This switch only affects the signals to the internal amplifier and does not affect signals going out from the internal mixer, or to signals passing through the Link connections.

7. Mixer On/Off

The Mixer On/Off switch turns the NX55P’s internal mixer on the rear panel on and off. The NX55P’s mixer should be used when a microphone or CD player is directly connected to one of the NX55Ps Line/CD or Mic inputs. It should be switched off* if the NX55P’s Link Input is connected to a separate mixer’s output.

*Note: the NX55P has been designed to enable the user to interconnect multiple NX55Ps (up to 12 or even more) via the Link Inputs and Outputs. When linking NX55P's, a maximum of 3 of the NX55P’s internal mixers can be used (activated) allowing up to 3 microphones and 3 line sources to be mixed without an external mixer. This is useful for smaller music engagements, meetings, seminars, etc.

8. 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.
