Reference Manual
Features
Compact dimensions and high output.
Dual coil woofer provides multiple wiring configurations.
Recessed connectors allow the enclosure to be used against a rear wall.
Built in low pass crossover for the woofer.
Outputs with hi pass crossovers to power satellite speakers.
Active sub input with crossover bypass.
Flexible positioning. May be used both horizontally or vertically.
System Connections
F or use with a stereo power amplifier and up to four satellite speakers
Position the Sub on the floor near to the satellite speakers. Placement can be either vertical or horizontal.
Under seating or other hidden positions are good options for placement, but make sure the two ports on the
enclosures front are not blocked. For best results keep both ports close to the ground when used vertically.
Connect a maximum of two satellite speakers to the Mycro Subs left ( L ) output and a maximum of two
satellite speakers to the Mycro Subs right ( R ) output. Connect the outputs from your stereo amplifier to the
left and right passive inputs on the Mycro Sub. For the Sub to work in passive mode the passive/active mode
switch must be set to its in ( ) position. The Mycro sub comes factory set to work in passive mode.
How to use the active input.
In active mode the internal passive low pass filter is bypassed, so you will have to power the Mycro Sub via
an external active crossover. Set the active crossovers hi pass filter to 35 Hz and its low pass filter to 150 Hz.
For optimum results use either 18 or 24 dB per octave slopes on both hi and low pass filters.
Next locate the passive/active mode switch on the rear connector panel on the Mycro Sub. The switch can
be found just below and between the output L and R speakons. Use a small screw driver or other pointed
object and press the switch so that it is in its out ( ) position. The Mycro Sub is now ready to work in
active mode. This can be confirmed by looking at the mode switch which should now be protruding from the
rear panel. Please note that the switch is factory set to passive mode.
The woofer has two voice coils, one is wired to +1, -1 and the other coil is wired to +2, -2. Each coil has an
impedance of 8 ohms. The Sub can be powered by a stereo amp with +1, -1 connected to one channel and
+2, -2 to the amplifiers other channel. If the Mycro Sub is to be powered actively from one amplifier channel,
c1 and +2 together and -1 and - 2 together at the speakon or amplifiers terminals. In mono
configuration the woofer has an impedance of 4 ohms and has a power rating of 400 watts rms.
Precautions
1. Install the Mycro Sub in a dry environment, do not expose the cabinet to rain or moisture.
2. When positioning the Mycro Sub in a hidden location or under seating, do not block the front ports.
3. When using the active input, make sure the active/passive mode switch is in the out ( ) position.
