Operating Manual - NE Multi Channel Power Amplifier

4. REMOTE AMPLIFIER CONTROL

ON/OFF/Remote Standby

The NE multichannel amplifiers have three possible states, OFF, ON, and STANDBY, each with a status LED on the front panel.

Control for these three states is managed by the following:

1) Power Switch - When the power switch is turned off the amplifier is completely off, UNLESS the power switch has been

disabled from software, in which case the power switch on the amplifier has no effect at all. If the power switch has been dis-

abled, the front panel DISABLE LED will be lit. Even if the AC power is removed, the amplifier's internal memory will retain

the <power switch disabled> status until changed again from software. Performing a factory reset will clear and restore all

internal amplifier memory to original factory settings.

2) Remote Standby Contact Closure - When these two pins are wired to a switch and connected

closed, the amp will go into standby mode, whereby the amp is active but in a reduced power state.

For remote standby to work, the power switch must be turned on or on but disabled in software.

3) Software On/Standby - On/standby in software functions the same as the remote standby

contact closure on the back panel. Clicking on STANDBY places the amp into standby mode.

Software on/standby does not override the hardware Remote Standby, they both remain active.

4) Software Power Switch Enable/Disable - This feature disables the front panel power switch. If the power switch is disabled

from software, the front panel DISABLE LED is lit. The power switch remains disabled until enabled again from software, even

after the amp is unplugged from AC.

Preset Recall

The preset recall connections on the back panel allow different presets to be loaded from amplifier memory when one of the

contacts is closed to the provided ground pin. Device presets are configured from software and can include gain settings, mute

status, polarity, and DSP functions if the amp has DSP installed.

The NE amplifier stores up to 35 internal device presets. A device preset stores the most commonly used control data for that

amplifier. A device preset (saved to amplifier) differs from a computer preset file in that a computer preset file stores all infor-

mation associated with the amplifier and its software settings, while the device preset only stores the most commonly used and

relevant audio settings. Changes to an individual preset can be saved to the amplifier in software using <Preset Options/Save

Preset To Device>, or saved to a PC using <Preset Options/Save Preset To File>. Sub Presets (collections of DSP parameters

individually selected from software) are saved in a similar fashion. Individual preset files use the extension (*.pne).

Loading a preset can be done using software, using preset recall contact closure connections on the back panel, using an Ashly

programmable remote button controller, or using the Ashly Remote iPad

app. Contact closure pins P1 through P4 load device

presets 1-4 from the amplifier memory.

Caution: A new preset may have dramatically different settings capable of damaging sound system components. Be careful not

to recall the wrong preset while the system is on.

Data Control

The data euroblock on the back of the amplifier is used for connecting an Ashly WR-5 programmable zone controller or RD-8C

remote level controller. The data interface provides data and phantom power for these devices using four conductor bell wire.
