4. Phase Select
Because low-frequency signals have long wavelengths compared to the dimensions of most rooms,
subwoofers often tend to cause room modes and cancellations that can be quite dramatic. For this
reason, we have included a phase inversion switch, which causes a 180° phase shift in the sub-
woofer's output. This allows you a greater degree of freedom in choosing where to locate the SBX10
unit (and consequently, the crossover frequency phase alignment) in your monitoring environment. Note
that the Phase Select function only affects the signal going to the subwoofer amplifier, and does not
affect the signal going to your direct-field monitors.
5. Unbalanced RCA Inputs
These jacks accept unbalanced RCA connections.
6. TRS Inputs
These jacks accept 1/4” connections with either
balanced or unbalanced wiring. For balanced wiring, a
three-conductor TRS plug is necessary. The wiring of a
TRS connector should be as follows:
TRS TIP . . . . . . . . . . signal positive (+)
TRS RING . . . . . . . . . signal negative (–)
TRS SLEEVE . . . . . . . signal ground (shield)
Unbalanced 1/4” wiring can be done with either a two-
or three-conductor (TS or TRS) plug. A two-conductor
(TS) plug automatically grounds the signal negative input,
whereas a three-conductor (TRS) plug, wired
unbalanced, provides the option of leaving the negative
input open or grounded. We recommend that you
ground the unused negative input (this can be done by
wiring the ring and sleeve of the TRS plug together).
7. XLR Inputs
These jacks accept XLR connections with either balanced or unbalanced wiring. The wiring of an XLR
connector should be as follows:
XLR PIN 1 . . . . . . . . . signal ground (shield)
XLR PIN 2 . . . . . . . . . signal positive (+)
XLR PIN 3 . . . . . . . . . signal negative (–)
8. Bass Reflex Port
The SBX10 subwoofer has a vented enclosure containing a custom bass-reflex port tube with a circu-
lar cross section on the rear of the enclosure. The port effectively gives the subwoofer a smooth
response down to 20Hz, and since its low-frequency contribution complements that of the front-firing
woofer driver, the woofer stays linear and distortion-free throughout the passband. The port has also
been designed using Failure Mode and Effects Analysis (FMEA) software in order to maximize output
and minimize audible port air turbulence noise.
Note:
If the TRS and XLR Inputs are
connected at the same time, the TRS
Inputs will take priority, and the XLR
Inputs will be muted.
If the RCA Inputs are used at the same
time as either of the TRS or XLR Input
pairs, audio will be heard from both.
However, it is recommended that you do
not play audio through both connectors
simultaneously as this may overload the
inputs and result in clipping (distortion)
at the inputs.
