GRADIENT XO-AMP
USER GUIDE
CONNECTIONS
The Gradient XO-AMP shall be connected like an ordinary power amplifier, after the preamplifier. The XO-
AMP is equipped with balanced Neutrik XLR - connectors. The speaker connectors are professional Neutrik
speakON connectors. The speakers shall be connected in the following way:
Speakon 1 + -> Gradient SW + ; Speakon 1 - -> Gradient SW -
Speakon 2+ -> Main s ; Speakon 2- -> Main speaker -
If one wish to use an external power amplifier, for example tube amplifier, for the midrange and treble, the
XO-AMP has a line level high frequency output from the XLR-male connector.
The speakON speaker connectors feature a unique metal locking system, making contact only once fully
locked. The speakON connectors are robust, versatile and easy to terminate.
Two 4-pole SpeakON cable connectors are included. They are extremely reliable and robust cable connectors
with a locking system. They feature solid contacts with screw-type terminals including a stranded wire
protection which offer also solder termination.
The AC-connector is professional Neutrik lockable powerCON-connector.
BASS LEVEL CONTROL
The level of the signal, feeding the bass amplifier can be adjusted continuously by a trimmer adjustments at
the back of the unit. The adjustment range is +/- 1 0dB for both channels separately. According to the personal
taste and listening room acoustics the bass is easy to adjust. Once found the correct balance, there is a little
need for further adjustments.
