Question 1

How to connect the M-CUBE to an AV receiver without a subwoofer output?

Accepted Answer

The M-CUBE SUBWOOFER from MISSION can operate even if your AV receiver does not have a dedicated LFE (subwoofer) output. Here’s how to connect it:

Connection without dedicated LFE output

The manual indicates a crucial point: the subwoofer will only work if you connect ALL channels of the receiver to the subwoofer via the umbilical link. This means that even without an LFE output, you can utilize the speaker-level inputs.

Proceed as follows:

Connect the multi-pin plug to the “SPEAKER INPUT” of the M-CUBE
Strip and connect the wires of the umbilical link to the speaker outputs of your receiver (left/right front channels, center, rear if available)
If your receiver has an LFE output, also connect the LFE cable to the “LFE IN” of the subwoofer

Important: Turn off the amplifier before making any connections. The umbilical link of the M-CUBE is specifically designed to allow this connection flexibility, even on receivers that do not have a dedicated subwoofer output.

Question 2

How to connect the M-CUBE SUBWOOFER to a 2.1 audio system?

Accepted Answer

To connect the M-CUBE SUBWOOFER to a 2.1 system (left, right + subwoofer), you need to use the supplied umbilical cable and connect all channels of the AV receiver.

Connection Steps

1. Strip the wires of the umbilical cable and connect them to the five speaker outputs of your receiver. Each wire is labeled (LFE, Front L/R, Center, etc.).

2. On the subwoofer:

Connect the multi-pin connector to the "SPEAKER INPUT" of the M-CUBE
Connect the LFE cable to the "LFE IN" input of the subwoofer

Important point: The subwoofer will only work if you connect ALL channels of the receiver. The manual explicitly states this: the left/right front channels, the center channel, and the LFE connections are mandatory for its proper operation.

Relevant specifications for your setup:

Frequency response: 28-300 Hz (-6 dB)
Crossover: adjustable between 250-300 Hz
Output power: 200 W

Once all connections are made, the M-CUBE will manage the extraction of low frequencies and transmit the remaining signals to your satellite speakers.
