Description The MicroMain27 Gen2 is a 3.5-way active loudspeaker capable of nearfield, mid-field and far-field operation.
2. 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. Rear panel VAC Select switch location Please read and follow the safety information below: Do not remove the rear amplifier panel. There is a risk of electric shock.
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.
4. Connections Analog: Digital: Analog Source AES3 Source AES/EBU Splitter * See Section 9 for Voice connection details. 5. Startup 1. Verify that the AC Voltage select switch on the rear panel is in the correct position for the AC voltage in your facility (see warnings on pervious page for details) then plug in grounded mains power cable. 2. Set Input toggle switch to either analog (A) or digital (D) depending on the type of source signal you are using.

. Protection Limiters Peak Limiter The Subwoofer, Midbass and Tweeter channels have individual Peak Limiters designed to protect each driver from high amplitude, 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. BAREFOOT text BAREFOOT text Cooling While the Hypex amplifier modules that drive the MicroMain27 Gen2 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 subwoofer cones. In order to ensure proper airflow, a minimum of 5” (127mm) clearance should be maintained between the speaker and any large obstructions.
. MEME™ (Multi Emphasis Monitor Emulation) With the MM27 GEN2, you can box up your secondary reference monitors for good. Despite the advantages of high-resolution monitors, many engineers still rely on their NS10s and mix cubes as secondary references. These speakers have long traditions and people find them familiar and useful for focusing in on certain aspects of their mix.
MEME™ Voice Selector Connection: The MEME™ 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. Furthermore, 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 with the MEME™ Voice Selector switch.
. Maintenance Exterior surfaces of this product may be cleaned using a non-abrasive lint-free cloth lightly damped with water. Disconnect the mains power cable when cleaning to avoid risk of electric shock. Do not use alcohol-based cleaners. Driver active surfaces such as diaphragms and surrounds may be cleaned using dry soft bristle brushes. Driver diaphragms are very delicate and easily damaged. So proceed with great care. Clean new sable artist brushes or cosmetic brushes work well for this task.

14. Warranty This product is under limited warranty as described in the following conditions. The warranty period commences on the date of purchase from the authorized dealer. Barefoot Sound reserves the right to request your original purchase receipt as proof of the date of purchase. The warranty follows the product and is transferable to any subsequent owner(s) as long as a copy of the original purchase receipt from the authorized dealer can be provided.
Appendix: Sound Anchors Stand Vertical Mounting Procedure Note: There are two variants of Sound Anchor stands designed for the MM27. Earlier models have 1” thick tubular steel mounting brackets. These require 2” long 5/16”-18 screws to fit the MM27 Gen2. Newer Sound Anchor stands have 0.5” thick solid aluminum mounting brackets. These require 1.5” long 5/16”-18 screws to fit the MM27 Gen2. Please check the size of the mounting screws supplied with your Sound Anchor stands to insure a proper fit.
