SET UP INSTRUCTIONS
1. Place loudspeaker in the desired location. Ensure that it is secure and stable.
2. Rotate the input attenuator knob counterclockwise 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 counterclockwise 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. It is
not necessary nor advisable to use any third-party outboard processing with BASSBOSS powered loudspeakers.
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 total power draw of one ZV28 amplifier module is 15A. Only one ZV28 should be connected to a 20A circuit. There is a power pass-
through on the ZV28. The typical power draw of one ZV28 amplifier module is 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. 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 counterclockwise (left) results
in an effective crossover frequency of 80Hz. Rotating it fully clockwise (right) results in an effective crossover frequency of 100Hz.
