Master Out/Slave In; Subwoofer Bypass Foot Switch; Remote Indicator - Mackie HRS120 Owner's Manual

Frequencies below the crossover frequency
are sent to the subwoofer, and frequencies
above the crossover frequency are sent to the
LEFT and RIGHT OUTputs, which are con-
nected to the main/satellite speakers.
Set the crossover frequency to the lowest
frequency response rating of the main/satellite
speakers.

MASTER OUT/SLAVE IN

Balanced XLR and unbalanced RCA female
connectors are provided for the MASTER OUT/
SLAVE INputs. Use these for daisy-chaining two
HRS10s by connecting the MASTER OUT jack
from the first subwoofer to the SLAVE IN jack
on the second subwoofer (see note below).
The SLAVE IN bypasses all filtering, but is
affected by the POLARITY and INPUT SENSI-
TIVITY settings.
The MASTER OUT is post-filtering (vari-
able and elliptical crossover, subsonic filter,
and LFE gain) and pre- POLARITY and INPUT
SENSITIVITY.
Note: You cannot daisy-chain more than one
additional subwoofer using these connections.
If SLAVE IN is used as an input, the MASTER
OUT has no signal present. To connect more
subwoofers, connect the MASTER OUT from
the first subwoofer to the LEFT (MONO) IN-
put of the second subwoofer with the FILTER
BYPASS switch pushed in. Then connect the
MASTER OUT of the second subwoofer to the
LEFT (MONO) INput of the third subwoofer,
and so on.

SUBWOOFER BYPASS FOOT SWITCH

This is a 1/4" jack for connecting a normally-
open footswitch. When the switch is closed, the
subwoofer is muted and the LEFT and RIGHT
OUTputs pass the full-range signal to the main/
satellite speakers.
This is useful for making a quick com-
parison between the HRS10 enhanced and
non-enhanced low-frequency playback.

REMOTE INDICATOR

This is a 1/4" jack for connecting a remote
indicator to indicate when the subwoofer is
bypassed. An internal relay closes, shorting
the tip and sleeve of the REMOTE INDICA-
TOR jack whenever the subwoofer is in bypass
mode, either triggered manually with the
FOOT SWITCH or by the auto-off function.
This can be used to turn on a remote, low-
voltage lamp. Note that this jack does not
provide power. It accepts a maximum of 4 VDC
