5  nX SERIES REAR PANEL FEATURES

5.1 Channel Configuration DIP Switch

 

- The DIP 

switches configure each channel's 80Hz 2nd Order Hipass 

Filter, Output Clip Limiter, Amplifier Gain, and Output 

Mode. In the example to the right, the DIP switch is set as 

follows: 

6

: 80Hz High Pass Filter is Off

5

: Clip Limiter is 

On

4&3

: Gain is 1.4V

2&1

: Output Mode is Low Z. 

Note: The Gain setting of 1.4V means that a 1.4V input will drive 

the amp to full output in any output mode. The other three Gain settings will apply their 

respective amplifier gain regardless of output mode, so the actual input voltage required 

to fully drive the amp will vary based on the selected output mode. 

5.2 Euroblock Input Jack

 

- Used for wiring a balanced input. If using an unbalanced 

signal, wire the input signal to the (+) pin, the shield to (G), and wire the (-) input pin to 

ground. Euroblock pins are wired in parallel to the 1/4" TRS and XLR combo jack.

5.3 Remote DC Level Control

 

Each channel has a potentiometer circuit available for 

remote DC Level Control. The example to the right illustrates a typical DC level control application. 

There is no limit to wire length, but do not use any other ground source. If multiple remote DC level 

controls are used for different channels, the same ground and V+ sources can be shared.

5.4 Combo Input Jack

 

The combination 1/4" TRS and XLR jack (pin 2 hot) is wired in 

parallel to the euroblock input. Do not float the TRS ring or XLR pin 3, connect it to (-) signal or 

to ground (if unbalanced).

5.5 Bridge Mode Switch

 

This switch places an adjacent 

channel pair into bridge mode, combining two amplifier outputs 

for more power to a single speaker load. Bridge mode uses only the 

odd numbered input channel and level control, disabling the even 

numbered input. Speaker outputs for bridge mode must be wired 

according to the chart shown to the right. The bridge mode switch 

button can be removed for added security by pulling it straight off.

5.6 SpeakON

®

 Output Jack Wiring

 

SpeakON output 

jacks provide safe, secure, and reliable loudspeaker connections, 

preventing external contact with potential hazardous voltage. See the speaker wiring diagram above or on the amplifier back panel for 

SpeakON pin connections and channel assignments for normal or bridge mode speaker wiring. See sec 5.5 to use bridge mode.

5.7 PowerCON

®

 AC Mains Connector 

Always use the AC cord provided by Ashly for connecting to mains power. The 

amplifier auto-detects mains voltage from 120VAC to 240VAC. 

WARNING: Do not remove or lift the mains connector ground. 

5.8 Serial Number Sticker

 

- This sticker identifies the product model number, serial number, MAC address (if network

-

able), and AC mains current/power rating.
