Crossover point frequencies
are changed internally by
varying the value of 4 resis-
tors per channel. Full details

• Balanced XLR Inputs
and
Outputs
• Additional summed mono Low output
• 2 way/3 way mode switch
• Low and High Output controls for 2 way mode
• Low, Mid and High Output controls for 3 way
mode
The crossover shall be a dual channel 2 way
or single channel 3 way unit in a steel chas-
sis six inches deep and one rack unit high.
There shall be a rear panel switch to put
the unit into either mode. The crossover
shall have true Linkwitz Riley 24 dB per oc-
tave, phase corrected state variable filters.
The front panel shall feature controls for
Low and High frequencies in dual channel
mode, and Low, Mid and High frequencies
in single channel mode.
There shall be corresponding outputs on the
rear panel, plus a separate mono low fre-
quency summed output. Each output will
have up to +6dB of gain available, to com-
pensate for amplifiers and speakers of dif-
fering sensitivities. There shall also be a pre-
set 30 Hz High Pass filter to remove unwant-
ed subsonics.
The unit shall have electronically Balanced
inputs, on TipRingSleeve (TRS) jack connec-
tors (Tip +, Ring -, Sleeve Ground), and XLR
connectors, with passive RFI filters and an
Input impedance of 20 Kohms (10 Kohms
unbalanced). The Outputs shall also be Bal-
anced, on XLR connectors, with an output
impedance of 300 ohms balanced (150 ohms
unbalanced),
The Input headroom shall be +21dB, with a
CMRR of better than 50dB, and the frequen-
cy response shall be 30 Hz, -0.5dB (as a func-
tion of the High Pass filter) to 20 KHz,
+0.16dB, and the maximum Output level shall
be +21dB, with a Signal to Noise ratio of -
93dB ‘A’ weighted (-90dB unweighted).
Total Harmonic Distortion shall be .004% @
0dB, 1 KHz, and the unit shall have a dynam-
ic range of 111dB.
AC Power shall be supplied via a removable
mains cable, connecting to an IEC connector
with an integral fuse and voltage change
switch on the unit’s rear panel.
The crossover shall be the ARX EC-2
