­The­ design­ brief­ for­ the­VS21­ waste­ create­ product tha toffees reflow- frequency ­extension ­similar­ to­ the­ BASSBOSS­ vented­ dual­ 18”­ subwoofers­ in­ combination­ with­ the­ hard-hitting­ punch­ of­ the­ BASSBOSS­ horn-loaded­ sub woofers.­The­VS21 ­brengths­ worl d­o extendible­ frequency ­together­ with­ the ­worl d­o f­high-impact. You’re­ no­ longer ­for ced­ to­ choo se­e it her­deep­ OR ­punchy,­the­VS21­ offers­both.
The­VS21 ­is­ particularly ­versatile, able ­to­ satisfy­ the­ demands­ of ­hard-hitting ­live ­kick­ drumette­ despoiling­ bass­of ­an­808. For those whose shows span a lot of genres, the VS21 has got them all covered. The same size and shape as the Cerwin Vega L-36, the VS21 will deliver considerably much more output and deep bass.
Description
Vented, short horn hybrid single 21” powered and processed subwoofer. Frequency response ±3dB from 25-90Hz. Maximum continuous sine wave output 132dB.
Features
The VS21 features a massive displacement, long excursion 21” woofer, rear- loaded into a large acoustical volume that is tuned to a low frequency, and front-loaded onto a short horn. The vented enclosure section provides extended low frequency performance and the horn section provides increased upper frequency sensitivity and improved transient response.
Benefits
These features bring the benefits of extended low frequency together with the benefits of high-impact. Excellent transient response is delivered by the efficient performance of the horn at the upper end of the subwoofer range. Extended depth is delivered by the large acoustical volume, low tuning and the massive displacement of the long-excursion 21” woofer. The combination provides an immediate hit with the added power of full and effortless low-end extension. The resulting impression is one of a very ‘big’ or ‘heavy’ hit. Thanks to these attributes, the VS21 is extremely versatile, able to satisfy the demands of hard-hitting live kick drums as well as the deep, rolling bass of heavy synth tracks or an 808. The VS21 offers output SPL comparable to a bigger double-18” cabinet and allows more output to be focused forward thanks to its smaller frontal area.
Amplification­ and­ Processing
Powered by a 2400W RMS amplifier, the VS21 includes all the necessary electronics to allow it to be connected directly to your mixer with nothing but signal cable in between. The built-in processing is minimal and includes a low-pass filter that provides a broad, flat frequency response. There is no need for any EQ in the signal. In addition, a sophisticated limiter system protects the woofer from thermal and over-excursion damage, allowing the user to get maximum output from the loudspeaker for as long as necessary without concern about overdriving it.
Arrays
For larger events, several arraying options are facilitated. Block arrays, side-by-side arrays and front/ back Cardioid arrays (presets available in DSP) can be deployed securely thanks to the interlocking feet.

*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
Our ­proactive­ philosophy­ causes­ specifications ­to be ­subject ­to­ change­ when ever­improvement s­are­made.

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. ­CARDIOID­SWITCH
   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 check for power, switch to 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 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 (im) 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 your dealer or BASSBOSS support if the product is not functioning properly. 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
