Eden NA650 - Manual (Page 9)

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.
Tuner Out Jack – This standard ¼ inch jack is designed to provide a pre-
gain signal for connection to a tuner. It can also be used to provide pre-tone
signal to other devices such as a direct box or console. The signal is enough
to provide adequate signal to virtually every tuner on the market.
OPERATING INSTRUCTIONS
Mechanical and Thermal Issues – During operation, your amplifier should
always be placed away from sources of moisture or heat. Care should be
taken not to obstruct the ventilation holes on the bottom and sides of the
unit. In the event of thermal shutdown, you should eliminate the cause of the
thermal problem (poor ventilation, speaker loads lower than 2 ohms)
immediately. The supplied rack ears can be used to install your amplifier in
a conventional equipment rack for protection during transportation.
Electrical Connection – The NA650 requires at least 10 Amps of correctly
wired alternating current for proper operation. Providing less than 10 Amps
of power may result in poor amplifier performance, so it’s probably not a
good idea to plug all of your band’s gear into a single wall outlet.
