Operating Manual - NE Two Channel Power Amplifiers

Requirements

Ashly NE two channel amplifiers have specific physical, electrical and signal requirements for proper operation.

These requirements will vary depending on your specific application, setup, and the settings on the amplifier. When

setting up and testing your system, please take special care to double check all connections and settings. Please refer to

the specifications section of this manual for specific input, output and other figures.

4. REMOTE AMPLIFIER CONTROL

ON/OFF/Remote Standby

The NE two channel 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 within Protea

the power switch has been disabled from software, the front panel DISABLE LED will be lit. Even if the AC power is

removed, the amplifier's internal memory will maintain the <power switch disabled> status until changed again from

Protea

software. Performing a factory reset will clear and restore all internal amplifier memory to factory settings.

2) Remote Standby Contact Closure - When these two euroblock pins on the back of the amplifier (see amplifier

rear panel illustration #10) are wired to a switch and connected, the amp will go into Standby mode, whereby the amp is

active but not fully powered up. For Remote Standby to work, the power switch must be turned on OR be disabled

through Protea

software.

Software On/Standby - On/Standby in the Protea

3) Protea

channel amp software functions the same as the hardware based Remote

Standby Contact Closure on the back panel. Clicking on STANDBY places

the amp in standby mode. The On/Standby in software does not override the

hardware Remote Standby, they both remain active.

4) Protea

Software Power Switch Enable/Disable - Use this soft-

ware feature to disallow use of the front panel power switch. If the power

switch has been disabled from software, the front panel DISABLE LED will

light on the amplifier. The power switch will remain inactive until enabled

again from software, even if the amp is removed from power.

WR-1 Remote Level Control

Either amplifier channel can have remote attenuation by using a poten-

tiometer assembly such as the Ashly WR-1 and four conductor wire. The

WR-1 is a dual potentiometer remote volume control designed to fit in a

standard electrical wall box. Each volume control is connected to a terminal

block on the WR-1 circuit board, which in turn must be wired to the amplifier

back panel euroblock connector labeled "Remote Level Control" as shown.

CV-1 = Control Voltage for Channel 1, etc. There is no wire length limitation

for Remote Level Control. Do not connect the WR-1 remote level control

ground to any other external grounds.
