Important Safety Precautions Please note: Alto Professional and inMusic are not responsible for the use of its products or the misuse of this information for any purpose. Alto Professional and inMusic are not responsible for the misuse of its products caused by avoiding compliance with inspection and maintenance procedures. Installation

• Always install subwoofers in accordance with applicable electrical and building codes.

• Install the subwoofer according to its maximum weight. Check the specifications of your stage to ensure it can support the subwoofer's weight. Also, observe all safety precautions specified by the manufacturer.

• Do not mount multiple subwoofers on the same stand or pole.

• Always verify that the stand or pole is on a flat, level, and stable surface. Also, fully extend the legs of tripod-style stands, and ensure its legs do not present a trip hazard.

• Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn, damaged, or missing parts.

• Always be cautious in windy, outdoor conditions. You may need to place additional weight (e.g., sandbags) on stand's base to improve stability. Do not attach banners or similar items to any part of a loudspeaker system. Such attachments could act as a sail and topple the system.

• Unless you are confident that you can handle the subwoofer's weight, ask another person to help you lift it onto the stand or pole.

• Make sure your cables are out of the way of performers, production crew, and audience so they will not trip over them. Sound Level Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.S. Occupational Safety and Health Administration (OSHA) has specified permissible exposures to certain noise levels. According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in hearing loss. When using equipment capable of generating high SPL, use hearing protection while such equipment is under operation.

The typical range is approximately 100 feet (30 meters) with a clear line of sight. However, the range may vary depending on your source device and the environment. To maximize the range:

• Set your source device on a flat surface and make sure there are no obstacles between the subwoofer and your device (e.g., walls, furniture, etc.).

• Turn off your source device’s Wi-Fi.

• Turn off any unneeded 2.4 GHz devices in the nearby vicinity (e.g., other Bluetooth devices, baby monitors, Wi-Fi access points, microwave ovens, etc.).

• Try using a different Bluetooth source device (iPad or iPhone). Bluetooth signal strength varies between different devices. To pair the speaker to your Bluetooth device:

1. Do this on one subwoofer only: With the subwoofer powered on, press and release its

Pairing Button. Its Pairing LED will flash.

2. From your Bluetooth device’s settings page, enable Bluetooth and select Black Series as

the device. When paired successfully, the Pairing LED will light continuously. (This process may take up to 30 seconds.) Important: If your device prompts you to enter a PIN code to pair it to the speaker, enter 0000 (four zeros).

3. Once your device is paired to the subwoofer, the subwoofer will remember the device

even after power-cycling it. If the device does not reconnect automatically, go to your device’s Bluetooth settings page and select Connect to reestablish the connection. To erase all previous pairing settings, press and hold the Pairing Button for 10 seconds. The LED will flash to confirm the pairing records are erased. Now, you can pair to a new device. Live Drive Operation For more information about using Live Drive, visit altoprofessional.com/livedrive.7

1. Power Input: Use the included IEC

power cable to connect this input to a power source.

2. Fuse: If the unit's fuse is broken, lift

this tab to replace the fuse. Replace it with a fuse with an 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: Use this switch to

power the subwoofer on or off.

4. Power/Standby LED: This LED

illuminates when the subwoofer is powered on.

5. Standby On/Off Switch: By default,

this subwoofer has its Standby Mode enabled: when no incoming audio signal is detected for approximately 15 minutes, the subwoofer will enter a low-power state. The subwoofer will exit Standby Mode within 0.5 seconds of detecting an incoming audio signal. Change this recessed switch's setting to the Off position to disable this feature.

6. Logo On/Off Switch: Press this to turn the light in the Alto Professional logo on or off.

7. Polarity Switch and LED: Press this switch to toggle the polarity of the subwoofer's acoustic output. In

some cases, reversing the polarity can help reduce any interference in the frequency overlap between the subwoofer and main loudspeaker. When the LED is off, the subwoofer is set to its default positive polarity (the recommended setting when used with Black Series loudspeakers). When the LED illuminates red, the subwoofer's polarity is reversed from its default. Important: When using multiple Black Series subwoofers, make sure they are set to the same polarity to avoid cancellation of the bass frequencies.

8. Inputs: Use a standard XLR or 1/4" (6.35 mm) cable to connect your audio source to this input. This

input accepts both line-level sources only.

9. Input Volume Knob: Use this knob to set the level of the audio going into the inputs. The Black 18sub

is engineered to work seamlessly together with Black 10, Black 12, or Black 15 loudspeaker models. For optimal bass balance, set the Black 18sub input volume knob to the 12 o’clock-position detent, and set the Black 10, Black 12, or Black 15 volume knobs to their maximum clockwise position. Adjust the volume controls as needed to further fine-tune the audio level from each system.

10. Signal/Limit LED: This LED illuminates green when an incoming audio signal is detected. It

illuminates red when the audio signal level is too high and is being dynamically reduced to protect the subwoofer from damage or distortion. If this LED is continually illuminated red, or if the audio output sounds excessively distorted, then reduce the volume of the connected audio source, or reduce the setting of the Input Volume Knob. 11. Outputs: Use a standard XLR cable to connect this balanced output to the input of a Black Series loudspeaker. Audio is sent from this output at 0 dB.

12. Crossover Bypass Switch and LED: Press this switch to toggle between Standard and Bypass

Modes. When the LED is off, the subwoofer is in Standard Mode (the default) where the XLR outputs' signal is high-pass-filtered to be sent to a full-range loudspeaker. When the LED illuminates green, the subwoofer is in Bypass Mode where the XLR outputs' signal will be unfiltered and full-range (the XLR outputs effectively function as loop-through connectors in this case).

13. Ground Switch: Engage (depress) this switch to reduce hum or noise.

14. DSP Mode Button: Press this button to cycle through the subwoofer's internal low-pass crossover

DSP settings, as shown on the rear panel. The LED next to the setting will illuminate when selected. For most applications, we recommend using the 80 Hz or 100 Hz setting; use the 120 Hz or 140 Hz settings to increase mid-bass impact.

15. Pairing Button and LED: Press and release this button to pair the subwoofer to your iPad or iPhone.

The Pairing LED will illuminate when it is paired. See the Bluetooth Pairing section for instructions.

5. Interruttore Standby On/Off: in via predefinita,
