Quality 200W Active Subwoofer CabinetOverview - Perfect for use at home, our stylish, compact and powerful active subwoofer will give you a quality bass note and achieve low ranges of sound that your standard speakers cannot. Simply run from your amplifier directly to the active sub, then out of the sub to your speakers. The cabinet is made from wood and other high quality components including an 8” reinforced Driver and an internal amplifier with an active filter circuit. This will give your current speakers a surprising level of depth and warmth that they would never be able to achieve on their own. If you require any speakers to go along with this product, please feel free to get in touch and we will suggest the right ones for you. How to install:Connect the Sub to the mains using the mains lead supplied or an equivalent, good quality fig.8 mains lead. Ensure that the mains voltage is as stated on the rear panel and the outlet has sufficient capacity to operate the sub.Determine how the sub unit is to be configured. If already operating a stereo amplifier with 2 speakers, the M8S can be configured to “tap off” a signal from the amplifier output without affecting the power output of the left and right speakers.Simply connecting the Left and Right amplifier outputs to the “AMPLIFIER HI LEVEL IN” terminals on the Sub and then from these terminals onto the left and right speakers effectively connects the Sub between the amplifier and speakers, which can simplify wiring, removing the need for a separate signal lead to the sub unit.Alternatively, if a separate line level audio signal is available, connecting left and right RCA cables to the “LINE IN” connectors is preferred (left and right signals are fed independently to the speaker and are not electrically summed)With the VOLUME control turned fully down, switch on the power on the rear panel. Once powered up, gradually turn the VOLUME up part way and play a signal through the system. Increase VOLUME as required.
