Ashly mXa-1502 12-Channel 4-Zone DSP Mixer-Amplifier - Manual (Page 6)

2.3 Cooling
Air vents on the amplifier front and side
panels must have access to free flowing room
temperature air. Cool air is drawn in through
the side and blown out the front. It is not
necessary to leave empty rack spaces above
or below the amplifier. See the BTU/hr table in
the specifications section for thermal output
characteristics.
2.4 Network
A standard 100MHz or faster network is required.
Connect the mXa-1502 Ethernet jack to a net-
work switch or router, or directly to a computer.
Once a successful Ethernet connection has
been made, a solid green LED (Link) lights up on
the RJ-45 Ethernet port. If there is no green LED
showing, there is either a problem with the cable
or network connection which must be addressed
before proceeding further. All RJ-45 Ethernet
ports flash green when active, so backtrack
through any other cables, routers, or switches
to find the problem. The flashing yellow LED
(Data) indicates that data is flowing to or from the
device. See section 5 for detailed instructions on
mXa-1502 network discovery.
2.5 Browser and Resolution
Supported browsers include Chrome, Edge
(Win10 recommended), and Safari. The
software requires a minimum screen resolution
of 1024 x 768. For use with a tablet, a minimum
screen size of 10" is recommended.
3 Front Panel Features
3.1 Mounting Holes
For rack mounting. Always use all four screws.
3.2 Cooling Vents
Cool air enters the sides and is vented out
through the front.
3.3 Device Reset Switch
There are two levels of device reset, Admin reset
or Factory Default reset, determined by how long
you press and hold in this recessed switch during
a cold-boot power-up.
A cold-boot power-up means that AC power is
removed before initiating reset.
To initiate reset, first press and hold in the reset
switch using a pencil-tip or paperclip, then
insert the power cord or turn on the power
outlet the device is plugged into. During the
reset process, all channel LEDs will light up from
bottom to top, followed by the four status LEDs.
To cancel reset before it completes, release the
reset switch before the green Signal LEDs turn on.
1) Admin reset changes the Admin User ID
password back to <secret>, but preserves
all other user IDs/passwords, presets, and
settings. Use this level if you forgot the admin
password.
To perform an Admin reset, release the reset
switch after the green signal LEDs turn on,
but before the red Clip/Mute LEDs turn on.
2) Factory Default reset deletes all User
IDs and passwords, deletes all presets, and
restores all settings to factory default. Use this
level to completely scrub the device clean of
any previous programming.
To perform a Factory Default reset, release
the reset switch after the red Clip/Mute LEDs
turn on.
3.4 Channel LEDs
The red Clip/Mute LEDs flash when output
voltage is 0.5V below the output power supply
voltage, or when an input signal or DSP section
is clipped. This LED also lights when the output
channel is muted.
The green signal LEDs light when the output
voltage reaches -18dBu below rated output.
The green current LEDs confirm that amplifier
output is being delivered to a speaker load.
The yellow temp LEDs indicate that the
amplifier channel has reached an excessively
high operating temperature and will gradually
attenuate the signal to compensate. If unable
to sufficiently cool the channel, the amplifier
will put itself into protect mode.
3.5 Select Buttons
The four select buttons are initially
unassigned. They can be programmed in
software to perform preset/sub-preset
recall or source select. To program select
buttons in AquaControl ™ software, go to
[ Settings>Panels>Front Button Settings ].
