Page 8: Input Signal Wiring
Operating Manual - nX, nXe, and nXp Power Amplifiers 2.2 Input Signal Wiring Use shielded wiring for balanced or unbalanced audio signals. Shielding which is properly grounded will protect the signal from outside electrical interference such as RF, fluorescent lighting, and computer/display emissions. Unbalanced or single-ended (tip- sleeve) lines of less than 10 feet are generally ok, but for greater distance or noisy field environments, always use balanced signal. -

Operating Manual - nX, nXe, and nXp Power Amplifiers 4.4 Channel Attenuators – These control the input signal level to the amplifier, and work in conjunction with the remote DC fader level controls and the software control surface fader controls (if the amp is networked). When an input attenuator is turned fully off, it's red Clip/Mute LED turns on and stays on to indicate mute status for that channel. -

Page 23: Dsp Control
Operating Manual - nX, nXe, and nXp Power Amplifiers 9.4d DSP Control Tab All signal processing is done in the DSP control tab, with separate input and output sections and a cross-linking matrix mixer between. From left to right, each channel in the DSP tab includes the following features: Input/Output Channel Number - Click on this to use each channel's Clear, Copy/Paste, Link, and Sub Preset functions. - Page 24 Operating Manual - nX, nXe, and nXp Power Amplifiers Pluggable DSP Block Descriptions 1) Dynamics Controls Clip (Brick Wall) Limiter The Clip Limiter is a compressor with fixed ratio (infinite). It allows for user-adjustable threshold, attack time and release time. It also allows for assignment to a Link Group to link the parameters of this block with limiters on other channels.
- Page 25 Operating Manual - nX, nXe, and nXp Power Amplifiers Release Time - The rate (in ms/dB) at which the Compressor attenuation will return to normal, once the signal falls below Threshold. Link Group - Group to which all parameters are assigned, to facilitate simultaneous adjustment to multiple Compressors in the system.
- Page 26 Operating Manual - nX, nXe, and nXp Power Amplifiers Threshold Below Target - Determines the relative input signal level above which the Autoleveler increases gain, below which no action is taken. Ratio - This is the ratio of the input level change in dB to output level change in dB. It determines the degree of boost or cut applied to a signal to maintain the target level.
- Page 27 Operating Manual - nX, nXe, and nXp Power Amplifiers Ducking At Mixer(s) This feature is particularly useful when setting up multiple zones where only some of the output channels should be ducked (e.g. restaurants, courtrooms, etc.). When this feature is selected, each Matrix Mixer is allowed to enable or disable the Duck- ing on that particular output.
- Page 28 Operating Manual - nX, nXe, and nXp Power Amplifiers Ambient Noise Compensation (output channels only) Ambient Noise Compensation (ANC) is an automatic output level control that uses a microphone to monitor background noise in a specific zone, then adjusts the out- put level to that zone accordingly in order to maximize intelligibility.
- Page 29 Operating Manual - nX, nXe, and nXp Power Amplifiers ANC Setup Procedure 1) In the control software, assign the ANC function to the channel to be used for background music or voice paging (program audio). Set the ANC controls to the "typical" settings described above, which is also the default settings of a new ANC function when it is first placed in the signal processing block.
- Page 30 VCA Groups. RD-8C Remote Control Gain Remote Gain allows the user to choose where Ashly's RD-8C will apply gain to a signal path (WR5s are handled by the WR5 Gain Block). When the remote is assigned to a channel, it applies gain/attenuation within the remote gain block, allowing the other gain blocks to remain unaffected by the remotes.
- Page 31 Operating Manual - nX, nXe, and nXp Power Amplifiers neWR-5 Remote Control Gain WR-5, The WR5/neWR5 Gain block is the DSP block where channel gain adjustments are made via the WR5 or ne-WR5 remote. This block is nearly identical to the standard gain block except that it is also controllable via the WR5 or ne-WR5 remote and does not have polarity inversion.
- Page 32 Operating Manual - nX, nXe, and nXp Power Amplifiers Parametric Equalizers (10, 6, 4, or 2 band PEQ) The Parametric Equalizer (PEQ) provides several types of filters to tailor the signal response with high precision. Four sizes are provided, with 2, 4, 6 or 10 filters. Filter types include Parametric, High-Shelf, Low-Shelf, Variable-Q High-Pass, Variable-Q Low-Pass, All-Pass, Band-Pass and Notch.
- Page 33 Operating Manual - nX, nXe, and nXp Power Amplifiers Level - Selected filter boost/cut amplitude. Bandwidth - Selected filter bandwidth (or Q). . Filter Type Details Parametric EQ Filters Parametric EQ uses peak filters with the ability to control boost or cut, frequency center, and bandwidth. Think of one band of parametric EQ as a single graphic equalizer fader, except that the frequency is variable, and that the bandwidth, or how "wide"...
- Page 34 Operating Manual - nX, nXe, and nXp Power Amplifiers Feedback Suppressor (Inputs only) The Feedback Suppressor (FBS) provides automatic feedback control. This is done by constantly monitoring the audio and automatically adjusting any one of 12 filters to remove feedback. Notch and Parametric Filter types are used, depending on the characteristics of the feedback.
- Page 35 Operating Manual - nX, nXe, and nXp Power Amplifiers Background Information The feedback suppressor uses both notch filters and parametric filters to automatically and quickly suppress multiple feedback tones and also produce a smooth equalized response which sounds pleasing for music and speech program. Before using the FBS (Feedback Suppressor), it is helpful to understand the following basic concepts in order to effectively suppress feedback and achieve good sounding audio program.
- Page 36 Operating Manual - nX, nXe, and nXp Power Amplifiers 4) Crossover Functions Four-Way, Three-Way, and Two-Way Crossover (outputs only) The Crossover tool offers a convenient way to configure amplifier outputs. Depending on whether the desired crossover is two, three, or four-way, all High-Pass (HPF) and Low-Pass Filters (LPF) are automatically placed on output channels. Initial crossover frequencies are assigned with the default filter type of 24dB/oct Butterworth, both of which can be changed.
- Page 37 Bessel These filters, as implemented in Ashly's NE devices, are always -3dB at the displayed crossover frequency. Bessel filters have a maximally flat group delay. Stated another way, Bessel filters have the most linear phase response. When a Bessel HPF and LPF of the same corner frequency are summed, the combined response is +3dB for 12dB/oct, 18dB/oct, and 48dB/oct Bessel filters, and -2dB for 24dB/oct Bessel filters.
- Page 38 Operating Manual - nX, nXe, and nXp Power Amplifiers 5) Delay Speaker Delay and Delay Both the Speaker Delay and Delay allow the signal to be delayed by a given number of samples (a given amount of time). The only differences between the Speaker Delay and Delay is the total amount of delay available and the amount of DSP resources used by each block.

Page 43: Front Panel Disable
Operating Manual - nX, nXe, and nXp Power Amplifiers 10.4 Sleep Clock Timer On all amplifier models, the sleep clock timer can be enabled or disabled using the front panel factory reset switch as described in section 4.3. On nXe and nXp series models only, the sleep clock timer can be adjusted from zero (off) to 120 minutes. If sleep mode is enabled, and there is no audio activity for the duration of the sleep clock timer (fixed at 30 minutes for nX series), the amplifier goes to sleep until signal is present again or until the power switch is pressed. -

The WR-5 is phantom powered from the amplifier. Up to four different WR-5 remotes can be wired in series and phantom powered from one amplifier, and more remotes can be added by using an Ashly RPS-18 remote power supply or equivalent. -
Page 47: Newr-5 Programmable Button Control
Connecting and powering the neWR-5 is done using Cat-5 Ethernet cable and an IEEE 802.3af Power over Eth- ernet (PoE) switch, hub, or in-line PoE injector. If PoE is unavailable, the Ashly RPS-18 (sold separately) provides 15-48VDC capable of at least 2 watts per neWR-5 and can be hard wired to the back of the neWR-5. PoE current draw is 38mA @48VDC and 80mA@15VDC. -
