The input impedance is high enough (20 kohms balanced) to
allow ”daisy-chaining”, or multiple parallel input
connections. The headroom of the input circuits is also great
enough to accept the maximum output level from virtually
any low-level signal source. Balanced signals are less
sensitive to AC hum and radio interference. The source
impedance should be less than 1 kohms to avoid high
frequency loss in long cables.
To daisy-chain amplifiers, use the XLR-male connector provided on each channel, labeled “Link”. They
are connected in parallel with the Neutrik® Combojack on each input.

To connect an unbalanced input source, connect pins 1 and 3 in the cable’s XLR plug (ring and sleeve in a
TRS plug). If you leave a pin disconnected, you will lose 6dB.
A better method for using unbalanced sources is shown in figure 8. This is similar to the connection for
balanced lines, but pin 3 is connected to the shield at the source end of the cable. The hum and noise
rejection for the cable is equivalent to that of a balanced line. To minimize hum in the audio signal, use
balanced inputs whenever possible.

For 2-channel (stereo) operation, use both channels A and B. For tandem stereo or bridged mono
operation, use only one of the inputs. See “Operation Modes” (page 7
) for more details.

Speaker connections are made via the two Neutrik® NL4FC Speakon connectors. The Speakon
connector is designed for high power speaker connections. It assures the correct polarity, it locks in place
and prevents from shock hazard.
They are wired in the following manner: The right jack, Channel A, provides both channel A and B
outputs, so it is useful for bridge and bi-amp operation (see bridge mono operation on page 7
). The left
Speakon, Channel B, carries only the channel B output.
