30Hz LOW CUT FILTER: eliminates unwanted subsonic frequencies under 30Hz. In most cases these
frequencies only consume a lot of energy without any added value to the music.

OPERATION MODE switch: Used to set the operation mode of the amplifier. The most common
operation mode is "stereo" . If you need more power, you can operate the amplifier in bridge mode. In
mono mode you only have to connect the left input to drive both outputs. Refer also to n⁰ 3 for more
information.

BALANCED XLR OUTPUTS: Can be used to send the signal to the next amplifier. Pin1: signal ground,
Pin2: Signal+, Pin3: Signal-

BALANCED XLR INPUTS: Pin1: Signal ground, Pin2: Signal+, Pin3: Signal-
HOW TO USE
STEREO OPERATION:
• Connect the audio signal to the inputs (15 or 16)
• Set the operation mode switch (13) tp "stereo"
• Connect the matching speakers to the L+R Speakon® outputs (11)
• Make sure the mains voltage matches 230Vac before connecting the
mains cable to the earthed wall socket
• Set both input gains (2) to zero
• Make sure there's a music signal at the input
• Turn the amplifier on (8)
• Adjust the input gains (2) to the desired level
BRIDGE OPERATION:
• Connect the audio signal to the left input (15 or 16)
• Set the operation mode switch (13) tp "bridge"
• Connect the matching speakers to the Bridge outputs (12)
• Make sure the mains voltage matches 230Vac before connecting the
mains cable to the earthed wall socket
• Set both input gains (2) to zero
• Make sure there's a music signal at the input
• Turn the amplifier on (8)
• Adjust the left input gain (2) to the desired level, leave the right channel gain to zero
MONO OPERATION:
• Connect the audio signal to the input of the left channel (15 or 16)
• Set the operation mode switch (13) tp "mono"
• Connect the matching speakers to the L+R Speakon® outputs (11)
• Make sure the mains voltage matches 230Vac before connecting the
mains cable to the earthed wall socket
• Set both input gains (2) to zero
• Make sure there's a music signal at the input
• Turn the amplifier on (8)
• Adjust the left input gain (2) to the desired level, leave the right channel gain to zero
