Euphonycart Present Yamaha STAGEPAS400. Whether you’re a public speaker, singer-songwriter, or in a band; the Yamaha StagePas 400BT is your all-in-one PA solution for pristine sound in smaller venues. The StagePas 400BT offers extensive connectivity. Equipped with Bluetooth wireless audio connectivity, the 400BT can stream audio to your StagePas system from any Bluetooth-paired device such as a smartphone, tablet, or laptop up to 33 feet away. The StagePas 400BT offers 2-band EQ on each channel. Four mic/line inputs feature XLR jacks, with phantom power on channels 1–2 and 1/4″ XLR combo inputs on channels 3–4; channel 4 is switchable to hi-Z for instruments with passive pickups. In addition, there are two stereo line input channels switchable for mono operation, plus support for RCA and 1/8″ stereo mini inputs. Monitor and subwoofer outputs on the 400BT provide easy expandability. For shows that require a monitor mix or extended low end, simply connect powered speakers such as Yamaha’s DXR Series full-range speakers or DXS Series subwoofers.
