Step 1 (Check your Voltage)
Look at the rear panel of each active DSP. A
voltage rating will be stated near the power
switch. Be sure that the indicated voltage rating
corresponds to the voltage supply in your country.
If there is a difference please do not proceed any
further and contact AXIOM for assistance.
Step 2 (DSP Input)
Your active DSPs will accept single-ended RCA or
balanced XLR input connections. If your amplifier(s)
AND your pre-amp/processor have available XLR
connections, we recommend their use for best
performance. If your amplifier(s) does not have XLR
inputs you should use RCA input connections. We
do not recommend using XLR to RCA converters.
Step 3 (DSP Output)
Each active DSP has five output connections
for one speaker channel. If you have ordered
an LFR1100 Active package that included
dedicated amplifiers note that each amplifier
channel is labelled for the corresponding DSP
and loudspeaker connection. We suggest that
you follow this connection scheme for best
performance. Connection from the DSP outputs to
the amplifier(s) can be RCA or XLR, but again we
recommend using XLR connections, even if your
input connections are single-ended RCA.
Connecting the DSPs
Step 3 (DSP Output) (cont.)
In addition to the amplifier output connections,
each DSP also has RCA and XLR outputs marked
SUB. This output can be used to send a full-range
signal to accompanying system subwoofers.
A Crossover Frequency control is located on
the back of each DSP to select a bass roll-off
frequency for each LFR active. Setting the control
to zero will allow the LFR active to operate full
range with no filtering. By using this control you
can tailor the overlap between your LFRs and
subwoofer(s) for the smoothest bass performance
and also off-load subsonic frequencies to the
subwoofer(s) which may result in better bass
dynamics and power handling from the LFR
actives.
Step 4 (Power Cord)
Connect the supplied power cords to your DSPs
and plug them into your power supply. Ideally
both DSPs and amplifier(s) will share the same
electrical circuit with your pre-amp/processor.
Turn on the main power switch on the rear panel
of each DSP. The front switch will now be active
for bringing your DSPs in and out of standby
mode. The led on each front panel will glow blue
to indicate your DSP is now ready for use.
