Page 12: Q-Nex Dsp Operations
Q-NEX DSP OPERATIONS The PRONET AX software must be used to control the Q-NEX amplifiers' built-in CORE2 DSP. All features of the CORE2 DSP are described in the PRONET AX user manual (see the HELP menu), so only some peculiarities of the Q-NEX amplifiers architecture are explained in this manual. -
Page 13: Pronet Ax Network
1. Switch on all the amplifiers. 2. Connect all the amplifiers with the network cable. 3. In the SETTINGS page of each Q-NEX amplifier device set “ID ASSIGN” as “AUTO-ID”: a different ID will be assigned automatically to at each amplifier. -
Page 14: Touch Display Operations
This column shows which page of the menu is active. To select the page, touch the screen or use the dial. The available pages are HOME (Axiom logo), ROUTING (folder), INPUT (faders), DEVICE (gear). This row shows the amplifier model and the name of the device assigned by Pronet AX. If the device is connected to a Pronet AX network and it is on-line, the row is red, if it's off-line the row is white. - Page 15 • Remove the output connection to check if there is a short circuit somewhere in the connected cable or the load. • Check if proper ventilation is ensured for the amplifier during its operation at all times. • Afterwards, if the warning notice persists, contact AXIOM service centre.

Page 16: Routing Page
Here you can see the name of the OUTPUT channels specified by Pronet AX or recalling a Preset. Q-NEX matrix system allows you to assign any physical input from 1 to 4 to any of the four DSP INPUTS A to D, then assign the four DSP INPUTS to any POWER OUTPUT DSP from 1 to 4. -
Page 17: Input Page
This example is a PA system for a typical large venue that has 4 inputs summed and routed to four zones with different systems, each with its own level, EQ, delay, and so on. INPUT PAGE This row shows the DSP INPUTS IN A, IN B, IN C, IN D. This row shows the current source input (1 to 4) assigned to each A to D DSP INPUTS. -

SPEAKER PROTECTION SETTING If you use Q-NEX amplifiers to drive an AXIOM passive loudspeaker system, the PRESET supplied or downloaded from the website already contains all the protection parameters for the speakers, also if they are not visible by the user, so you need only to recall it using PRONET AX software and store it in the amplifier memory. - Page 19 The Peak Dynamic Control has several parameters to be set properly if you want that it operates as a power limiter: • Detect must be set as MID, this parameter set the speed of the limiter detector. • Ratio must be set as Limiter or at least at 20:1, all ratio below could be not efficient to protect a speaker. •...
