1. Inputs
- For unbalanced inputs, the signal should be on the (+) connection and the (-) connection tied to ground. A
mono 1/4” plug used as an unbalanced connection will automatically be grounded. When using a stereo plug, or XLR
connector for an unbalanced signal, the (-) input connection MUST be tied to ground.
2. Balanced Outputs -
This output circuit is an active output which maintains a constant output level between the (+) and
(-) output terminals, regardless of either terminal being connected to ground. This servo-balanced output provides an
unchanged signal without regard to ground.
3. Power –
Switches the unit power on or off.
Installation
Before connecting to mains power, make sure that the switches are set to the configuration
needed for your particular application. Always switch the crossover off before making
substantial changes to the settings, especially the Range. Failure to do so could result in
damage to the unit or other components in your system. Use four screws and washers when
rack mounting. For mobile use, the unit should be further secured as appropriate.
General Requirements
XR Crossovers 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 unit. 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.
AC Power
Your XR Crossover should be connected to a standard 3-wire grounded electrical outlet
supplying 100-240 Volts, 50-60 Hz. To reduce the risk of ground loop hum, connect all
audio equipment to the same electrical power source. Do not remove the AC plug ground
pin, as a potential shock hazard could result.
This unit will perform normally within the AC voltage range specified above. Voltages
less than this, as found in “brown-out” conditions, may reduce performance. No user
serviceable parts are inside the chassis. Refer all servicing to qualified service personnel.
Overall power consumption is less than 30 watts.
NOTE
: The power switch does NOT isolate the appliance from mains. Make sure the mains
power socket or an alternative disconnect device is near by and easily accessible. When the
product is connected to mains, the line-filter and the input of the fuse are energized.
