3.1.2 Subwoofers: AIR15s and AIR18s

Line inputs. The AIR-series subwoofers feature two line-level inputs. These

balanced XLR / ¼” TRS combo connections are provided to connect your

subwoofer to a StudioLive-series mixer or other mixing console.

Power User Tip: Two inputs are provided in order to accept a stereo signal from

the output of the mixing console. Both channels should be connected, as the

low-frequency content from both channels of a stereo signal is summed before

the lowpass ﬁlter. However, either input may be used if the mixing console output

signal is mono only or if you are sending low-frequency channels (bass, kick,

keyboards, etc.) to a separate aux or subgroup output for the subwoofer only.

Outputs. Two line-level outputs (1 and 2) are provided to pass the stereo

signal from the subwoofer to full-range loudspeakers. The outputs are parallel

to Inputs 1 and 2, respectively.

Master Vol. This knob determines the master output level (volume) of the

subwoofer power ampliﬁer. It has no eﬀect on the signal level from Outputs 1

and 2. Push this control to access all the DSP functions in your AIR-series

loudspeaker.

Power User Tip: A subwoofer can signiﬁcantly change the frequency response

of a full-range system. A 3-way system with a subwoofer will be 6 to 18 dB hotter

below 80 to 100 Hz. Set the appropriate level for your subwoofer before adjusting

your system EQ.

3.2 Power

AC line connection. AIR-series loudspeakers have a universal power supply

that accepts AC power input between 100 and 250 VAC at 50/60 Hz. Each

loudspeaker is supplied with an IEC cord appropriate for the country of sale.

WARNING: Do not remove the center grounding prong or use a

ground-lift adapter, as this could result in electric shock.

Power Switch. This is the On/Oﬀ switch.

Power User Tip: If connecting multiple loudspeakers to the same electrical

circuit, make sure that adequate line current is available. The maximum current

draw for each AIR-series loudspeaker is listed in the Speciﬁcations in Section 4.1.

Voltage Selection. AIR-series loudspeakers are conﬁgured for the country of

sale. Only use this switch if you are using your loudspeaker in a country with a

diﬀerent standard voltage than the country where you purchased your

loudspeaker.

Fuse. This is the fuse housing for your AIR-series loudspeaker. The fuse type

for your loudspeaker is listed on the rear-panel.
