McIntosh MSE1 Surround Expander for Enhanced 6.1 Experience
Product Description
When you're looking to bring your McIntosh theater system from 5.1 to a full 6.1 experience, the McIntosh MSE1 Surround Expander is your answer. It's not just about adding an extra channel; it's about enriching the entire surround field. With a dedicated Back Surround (BS) channel, the MSE1 deepens the audio landscape, filling in the gaps between your left and right surrounds.
The MSE1's 24-bit DSP processing and 20-bit A/D and D/A conversion are designed to handle both automatically expanded BS-encoded soundtracks and standard 5.1 soundtracks in manual mode. This ensures you get the intended audio experience without creating artificial channels unless desired. The expander works in harmony with the McIntosh MX132 A/V Control Center, making it a seamless addition to your existing setup.
If you're setting up a dedicated home theater in Houston, this expander upgrades your space, delivering a more immersive experience. It's ideal for enthusiasts using the MX132 paired with a MC206 or MC126 multichannel amplifier. The MSE1 also supports non-McIntosh 5.1 decoders, offering flexibility across systems.
At MODIA, we pride ourselves on offering products that enhance your home theater experience. Visit our Houston showroom for a hands-on demonstration, or consult with our experts across Texas for installation and calibration tailored to your space.
