1. Power Input: Connect the included power cable to
this input and connect the other end of the cable to a
power source. Make sure the Power Switch is set to
off when plugging and unplugging the cable.
2. Fuse: If the unit's fuse is broken, power off the
subwoofer and disconnect it from the power outlet,
and then lift this tab to replace the fuse. Replace it
with a fuse that has the appropriate rating (printed
under the unit's power cable input). Using a fuse with
an incorrect rating can damage the unit and/or fuse.
3. Power Switch: Turns the subwoofer on/off. Make sure
the Volume knob is set to "zero" before turning it on.
4. Power LED: Illuminates when the subwoofer is on.
5. Outputs: Use standard XLR cables to connect these
outputs to a loudspeaker. The audio signal with
frequencies above the subwoofer's crossover frequency
will be sent out of these outputs. 1 is the left output, and
2 is the right output.
6. Inputs: Use a standard XLR cables (not included) to
connect your sound source to these inputs. 1 is the left
input, and 2 is the right input.
7. Volume: Turn this knob to adjust the subwoofer's
output volume.
8. Signal/Limit LED: This LED lights up green when an audio signal is sent to the
subwoofer—it flashes at lower levels and lights solidly at higher levels. The LED lights up
red when output limit/protection is active—if the LED is lit red continuously, reduce the
volume of your audio source.
9. Polarity Reverse Selector: Press this switch to reverse the phase of the subwoofer's
output. Use this to reduce phasing or cancellations caused by the subwoofer's location in
a listening space (low-frequency signals have longer wavelengths, which can cause these
unwanted effects).
Important: This affects the signal going to the subwoofer's amplifier only, not the signal
sent to the outputs.
10. DSP Output Mode: Press this switch to toggle between six settings that adjust delay,
crossover frequency and the level of the XLR outputs. The first four settings are specifically
tailored to the Alto Professional TS308, TS310, TS312, and TS315 full-range loudspeakers.
The last two settings may be useful with non-Alto Professional loudspeakers. When a
setting is selected, its corresponding LED will be lit. See
for more details.
Note: The subwoofer will always play frequencies below its crossover frequency, regardless
of the position of this switch.
11. Extended LF: Press this switch to enable or disable the extended low-frequency response
of the subwoofer. When enabled, the corresponding LED will be lit, and the lower
frequencies of the subwoofer will be boosted.
Note: If this function is enabled, make sure that the subwoofer's extended frequencies do
not cause any phasing or cancellation if they overlap with your loudspeakers' frequencies.
