&lt;p&gt;Because the EMX2 is both a mixer and a power amplifier you only need speakers and mics to have a fully functioning sound system. This makes it easy for newcomers and even first-time users with no previous audio experience to easily configure their own sound reinforcement system. The EMX2&amp;#039;s all-in-one design concept ensures that by just plugging in a single power cable and making a few simple intuitive connections anyone can be their own sound engineer.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;Premium Portability&lt;/strong&gt;&lt;br /&gt;Despite being a mixer and an amplifier in a single unit the EMX2&amp;#039;s dimensions (37.5cm x 22cm x 15cm / 14.8 x 5.8 x 8.7) are surprisingly modest making it easy to fit along with speakers even in the trunk of a small car. The lightweight body also features handles for a superior level of portability that will benefit anyone setting up a PA for applications where time is a consideration&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;From Speaking Engagements to Live Bands and DJ Events&lt;/strong&gt;&lt;br /&gt;The EMX2&amp;#039;s flexible connectivity allows you to use up to 4 microphones for singing along with musical instruments or speaking/ making announcements along with BGM or recorded audio from a portable playback device. The unit also comes equipped with Phantom Power and high-impedance input capability allowing you to use high-performance condenser microphones or connect guitars directly without any external gear. And because the EMX2 is also an amplifier you can easily connect passive speakers to complete your sound system or even add a Yamaha DXS Series Powered sub-woofer via a single connection for configuring a PA system for applications that require a more prominent bass performance such as a DJ event in a small club or outdoor venue.&lt;br /&gt;&lt;br /&gt;&lt;strong&gt;4 Yamaha Reverbs for Additional Atmosphere&lt;/strong&gt;&lt;br /&gt;For decades the sound specialists at Yamaha have been developing high-quality reverb effects to add an atmospheric touch to our users vocal and instrumental performances.
