Warnings! The Mains Voltage Select switch (VAC Select) on the rear panel must be in the 230V position for AC power line voltages over 132 VAC. Connecting the power cord to AC power line voltages over 132 VAC while the VAC Select switch is in the 115V position will damage the amplifier. Such damage is NOT covered under warranty.

1. Description The MiniMain12 is a four-way active loudspeaker capable of nearfield, mid-field and far-field operation. The seven drive units are all housed in sealed enclosures. The DSP controlled four-way power amplifier module can deliver 1200 Watts continuously. The system accepts either analog or 24 bit/192 kHz digital audio signals.
3. Inputs and Controls 1. [INPUT] Toggle switch selects between the analog (A) and digital (D) inputs. 2. [ANLG] XLR connector is designed to receive analog balanced line level audio signal from sources such as preamplifiers, sound cards, monitor controllers and mixing consoles. Pin 1 is tied to chassis ground. Pins 2 & 3 are fully floating differential inputs. Pin 3 must be referenced to ground for single ended input signals.

5. Protection Limiters Peak Limiter The Subwoofer, Woofer, Midrange and Tweeter channels have individual Peak Limiters designed to protect each driver from large, short duration audio input signal spikes that might cause damage due to over excursion of the voice coil. These limiters are implemented digitally within the DSP in such a manner that they have zero effect on the audio signal below their thresholds.
Example: Symmetrical stereo arrangements. Cooling While the Hypex amplifier modules that drive the MiniMain12 are a very efficient, the speaker still generates a significant amount of heat that must be dissipated. This heat is transmitted to the air via the rear amplifier plate, heat sink and the driver cones. In order to ensure proper airflow, a minimum of 5” (127mm) clearance should be maintained between the speaker and any large obstructions.
7. Voice Emulation With the MM12, you can box up your secondary reference monitors for good. Despite the advantages of highresolution monitors, many engineers still rely on their NS-10s and Auratones as secondary references. These speakers have long traditions and people find them familiar and useful for focusing in on certain aspects of their mix. However, it's also a fact that crowding your console with those extra boxes degrades the sound field of the primary reference monitors.
Voice Selector Connection: The Voice Selector switch box is connected to the Voice jack of the speaker via any standard 3.5 mm stereo phone cable. The included 6-way splitter can be used to control the Voice Emulation of up to 5 speakers. However, the input impedance of the Voice jack is very high. So, additional splitters can be daisy chained in order to control virtually any number of speakers.
