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 via the XLR input jack.
4. Connect the amplifier module’s power supply cord using the blue PowerCON connectors. To insert, align the indexing tabs on the
PowerCON connector, insert it into the socket and rotate clockwise until the latch catches.
5. Connect the electrical plug to a power source. Check that the “Ready” LED is illuminated.
6. Select the desired preset via the PRESET SELECT button.
7. Rotate the input attenuator clockwise to achieve the desired sound level.
CONTROLS:
Preset Select:
The AT312 compact full-range loudspeaker’s DSP is equipped with 4 presets. All four presets contain limiter settings to ensure safe operation. The presets are
accessed via the preset select button on the amplifier interface, between the XLR input and output connectors. When the button is pressed, each preset loads in
sequence, from 1 to 4, and then cycling back to 1. A green LED indicates the active preset.
Gain:
The level knob provides a range of control from OFF to +12dB within each preset.
Indicators:
Ready - Green LED - Indicates that the amplifier has power and is operational.
Signal - Green LED - Indicates the presence of signal reaching the amplifier inputs.
Temp - Amber LED - Indicates the amplifier is actively reducing level to prevent overheating.
Limit - Red LED - Flashing - Indicates that the loudspeaker is being overdriven.
Limit - Red LED - Solid or rapid blinking - Indicates amplifier is in protect mode.
Preset Functions:
Preset 1: Stand-alone Full-Range Operation. 45Hz high-pass filter. Recommended for use when no sub is available. Peak output is restricted to prevent low
frequencies damaging the loudspeaker.
Preset 2: Intermediate Stand-Alone setting, 60Hz high-pass. Recommended for use with a single sub or when subwoofers are separated from AT312s, such as when
subs are center-placed.
Preset 3: Intermediate High-Output setting. 75Hz high-pass. Recommended for use when single subwoofers are co-located with the AT312s, such as if the AT312s
are on a speaker pole above a subwoofer or on a tripod adjacent to a subwoofer.
Preset 4: Maximum SPL Setting, 90Hz high-pass. Recommended for use when outdoors, in larger venues and/or when multiple or larger subwoofers are co-located
with the AT312s.
Presets 2, 3 and 4 allow the AT312s to be combined with various subwoofer configurations and allow the sound to be tailored to different environments. It is
recommended to listen to the appropriate presets in each new setting and choose the one that works best in that environment.
System Setup Addendum:
When connecting multiple BASSBOSS loudspeakers in a system, signal can be passed through from one powered loudspeaker to another using balanced, shielded
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.
