IMPORTANT NOTE: In order to operate properly in other parts of the
world, your amplifier may require minor modifications. These
modifications must be made by a QUALIFIED technician. Contact your
local distributor for further information.
Speaker Outputs – These consist of two ¼ inch jacks and two NL-4
connector (sometimes called a Speakon). The jacks are wired in parallel. The
total speaker load impedance should not go below 2 ohms. On NL-4
connectors, we use +1, -1 connections.
D.I. Level – Controls the level being sent from the XLR balanced output
jack. We suggest setting the control at approximately 12 o’clock initially. If
the signal to the board is too hot, it’s better to engage the Input Pad on your
channel of the board than to turn it down here, if at all possible. In general,
it’s better (in terms of signal-to-noise ratio and dynamic presentation) to
send as hot a signal as possible to the board. However, you can adjust the
signal level, if necessary, so make sure your soundperson or recording
engineer is aware of this capability.
Ground Lift Switch – This switch lifts the ground within the balanced
output system to allow you to eliminate excessive noise/ground loops when
connected to external systems.
Recording Out (D.I.) – This fully balanced XLR output allows you to send
a pre- or post-EQ signal to a recording or sound reinforcement mixing
console. We use Pin 2 hot configuration. Adjusting the Master Volume
control will not affect this send. This output is designed to use with phantom
powered systems. However, it never hurts to turn off the phantom power at
the board, if possible.
Mono Pre-EQ Effects Send/Return – These standard ¼ inch jacks allow
you to send and receive your signal to and from external devices. This
effects loop is positioned post (behind) the compressor and before the
Enhance control and the tone section. This loop is at line level; do not use
instrument level effects in this loop as they tend to be overloaded by the
higher signal level which can cause distortion.
