Description

• For DJs and venues seeking extremely deep bass at moderately high levels, the DJ18S is a small, light and very cost-effective solution. Suitable for the truly bass-insatiable, whose focus is on modern music that features frequencies well below the usual 40-50Hz range, this extremely compact sub weighs only 110 lbs and delivers output down to 27Hz (-3dB ). By comparison, most similarly sized subs are going to be -10dB at 30 Hz. That’s an equivalent output ratio of 2:1 at the lowest notes. That means it would take 2 boxes with output that’s -10 at 30Hz to produce the same output as one DJ18S.

• The DJ18 is a single 18-inch direct-radiating subwoofer. Featuring a long excursion, 18-inch woofer loaded into a vented enclosure that is tuned to optimize extremely low frequency output using a very large port. The amplifier is loaded at the interior port end to utilize the air flow at
  high output for additional cooling The cabinet was designed to minimize materials, cost and
  weight and maximize efficiency.

• It includes a 2400W RMS amplifier, rated for RMS output using continuous sine wave signal. This is not a peak or burst power rating. The amplifier is capable of delivering 2400W of continuous
  output, ensuring that the amp isn’t the limiting factor in the output of low frequencies. Providing abundant power also virtually eliminates the possibility of overheating and damage to the woofers caused by clipping.

• All that electrical power is converted into acoustical power by a 18 inch neodymium motor woofer. This premium-quality driver features a copper-winding voice coil. High-intensity Neodymium magnets are lighter and provide higher efficiency so the result is a lighter and
  louder cabinet.

• Integrated, comprehensive DSP is included. Processing includes high-pass and low-pass filters as well as multiple protection systems and limiters to control all manners of driver overload, including thermal, excursion and clipping. The protection systems effectively prevent overheating of the voice coils and minimize long-term thermal compression while having virtually no effect on the transient response and peak output of the loudspeaker.

• The cabinets are constructed from 18mm Baltic Birch plywood, assembled using dado joints, screws and advanced composite adhesives. Stainless steel bolts are used to secure the drivers, amplifier and pole sockets. The cabinet is finished in an extremely rugged, black polyurethane coating.

• The driver is protected by a black powder-coated, perforated steel grill. The woofer cones are waterproofed so the cabinets are safe to use outdoors where they may encounter rain, in nightclubs where drinks may be spilled on them, or in dusty environments that may leave the drivers needing a thorough deep cleaning.

*Peak output is calculated using “industry standard” techniques. These calculation methods create theoretical specifications that are inflated over what can actually be achieved. BASSBOSS real world output specifications are provided as “Maximum Sustained Output” ratings, which reflect actual measured, continuous output levels.

Setup Instructions

1. Place loudspeaker in the desired location. Ensure that it is secure and stable.

2. Rotate the input attenuator knob counter-clockwise to the lowest setting.

3. Connect signal from the sound source (mixer) via the XLR female input jack.

4. Connect the XLR male output to the next available loudspeaker input via an XLR cable (if applicable.)
   This is a full-range pass-through connection and no processing is applied to this output.

5. Connect the Neutrik PowerCON (blue) connector to the blue power inlet socket. Do not force. To insert, align the indexing tabs on the connectors, insert the plug fully into the socket and rotate clockwise until the latches catch. To remove, pull back on the latch tab and rotate the connector counter-clockwise to the index stop, then pull outwards.

6. Work backwards from the speakers to the outlets, making all PowerCON connections before plugging in to mains power.

7. Connect the electrical plug to a power source.

8. Move the POWER switch to the ON position.

9. Rotate the input attenuator clockwise to achieve the desired sound level.

• The integrated DSP includes all the required processing for safe operation and alignment with the accompanying BASSBOSS top boxes. DO NOT USE third-party outboard processing with BASSBOSS powered loudspeakers. This will not improve, and will most likely degrade the sound quality and output capacity.

• When connecting multiple BASSBOSS loudspeakers in a system, signal can be passed through from one powered loudspeaker to another using XLR cables. No processing is applied to the signal as it passes through from the input to the output connectors in each loudspeaker. Signal can be routed in any sequence because each loudspeaker receives a full-range signal and applies the necessary processing in order to operate as part of the overall system. It is recommended to run
  signal to the nearest box first and patch to the next nearest box in sequence.

• When connecting BASSBOSS speakers in a system including other brands of loudspeakers, it’s recommended to connect the BASSBOSS speakers first in sequence, then connect other speakers to the pass-through outputs. This ensures that no inappropriate processing is applied to either loudspeaker.

• The typical power draw of one BASSBOSS 2400W amplifier module is approximately 5A. With heavy demand, the current
  draw can peak at 20A for brief periods but under NEMA code, a 20A breaker should sustain a peak draw of 40A for several seconds without tripping.

• It’s recommended to connect no more than two 2400W amplifier to an individual 20A circuit. In situations where circuits must be shared with other equipment or other brands, it’s recommended to power combinations of a BASSBOSS subwoofer and a top on a circuit and to power each subwoofer and top combination on a separate circuit to reduce the chances of overdrawing a circuit and tripping a breaker.

Operation and Controls

There are 2 control knobs on the amplifier.

1. GAIN
   Provides attenuation of the input from off to full output. Use appropriate gain structure to ensure the output feeding the subwoofer doesn’t reach clipping and distortion before maximum desired sound level is achieved. The amplifier has a complement of limiters and safeties to protect itself and the driver however, if audible distortion occurs, lower the level of the incoming signal.

2. EXO ADJUST
   This control adjusts the effective crossover frequency allowing the subwoofer to be used with multiple sizes and styles of top boxes while minimizing out- of-bandwidth noise and phase shift in the crossover region. Rotating the EXO knob fully counter-clockwise (left) results in an effective crossover frequency of 80Hz. Rotating it fully clockwise (right) results in an effective crossover frequency of 100Hz.

3. CARDIOID SWITCH
   Toggle Switch allows selection between NORMAL mode and CARDIOID mode.
   With the switch in the NORMAL (up) position, the speaker is in normal operating mode and any number of cabinets can be arrayed side-by-side facing the same way when they are all in NORMAL mode.
   When CARDIOID operation is desired, one or two cabinets must be used in NORMAL mode and at least one cabinet must be placed
   in CARDIOID mode and its position reversed relative to the other cabinet(s) The ideal ratio is 2 cabinets in NORMAL with one CARDIOID cabinet between them vertically or horizontally.

   • The NORMAL mode cabinet(s) are used with the woofer facing towards the audience. The CARDIOID mode cabinet is rotated with
     the woofer away from the audience and the CARDIOID SELECT SWITCH in the CARDIOID (down) position.

   • The cabinet in CARDIOID mode should have the EXO knob at the lowest level, rotated fully counter-clockwise. The EXO setting on the NORMAL mode cabinet(s) can be set to taste but all cabinets in NORMAL mode should be set the same.
     Note: When the speaker is in CARDIOID mode, the green PWR LED is disabled because it will be facing the audience. The speaker will still power up and play.

   • When only two cabinets are used, the cabinet in CARDIOID mode can be placed on top of the cabinet in NORMAL mode.
     The cabinet in CARDIOID mode can also be placed adjacent to the NORMAL mode cabinet, with the NORMAL mode cabinets placed farther from the stage or area where reduced level is desired. When only 2 cabinets are in use, the CARDIOID mode cabinet GAIN should be reduced by 3dB. The greatest level reduction occurs on axis with a line drawn from the center of the NORMAL cabinet’s baffle, through the center of the CARDIOID cabinet’s baffle.

Troubleshooting

If, after following the above instructions for setup, you have no output from the loudspeakers: Verify that the green power (ON) LED is lit. If not, check the following:

( Note: The ON LED is disabled when CARDIOID mode is selected. To c NORMAL mode to illuminate the LED)

1. Is the power cord plugged into a live outlet?
2. Is the Neutrik PowerCON connector rotated into the locked position?
3. Is the Power Switch on?

If the green power LED is on, check the following:

1. Is the signal cable connected to the input?
2. Is the signal cable connected to an operating output at the other end?
3. Is the signal flowing to the input? Check the integrity of the cable by using a different cable.
4. Is the attenuator turned all the way down or at a very low level?
5. Is the signal flowing to the input full-range? Filters in the signal may remove the operating frequencies of the loudspeaker receiving them.

Safety Information

Important information regarding safety and the use of your loudspeakers:

Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx. 95 dB SPL) can cause hearing damage if people are exposed to it over a long period. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices.
When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones.

See the manual technical specifications to know the maximum sound pressure level.

• In order to prevent accidents when setting up the loudspeakers or loudspeaker stands, make sure they are standing on a firm surface.
• Ensure that all additional hardware, fixings and fasteners used for installation or mobile deployment are of an appropriate size and load safety factor.
• Pay attention to the manufacturers’ instructions and to the relevant safety guidelines. Regularly check the loudspeaker housings and accessories for visible signs of wear and tear, and replace them when necessary.
• Regularly check all load bearing bolts in the mounting devices.

Caution: Loudspeakers produce a static magnetic field even if they are not connected or are not in use. Therefore make sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which may be impaired or damaged by an external magnetic field. A distance of 3 feet (1m) should be maintained between loudspeakers and sensitive equipment such as CRT monitors or magnetic storage media.

• Never attempt to carry out any operations, modifications or repairs that are not expressly described in this manual.
• Contact BASSBOSS support if the product is not functioning properly. Do not attempt to repair the product –
• We can help! BASSBOSS strongly recommends this product be installed by a qualified, professional installer who can ensure correct installation and certify that it is installed in compliance with the regulations in force.
• The entire audio system must comply with the current local standards and regulations regarding electrical systems.

Important Notes

To prevent the occurrence of noise on signal cables, use shielded cables only. Avoid routing signal cables close to equipment that produces high-intensity electromagnetic fields such as transformers, power cables and loudspeaker wires. Do not coil excess power cable. Do not coil or wrap power cables and signal cables together.
