スタジオ・ミキサー

Notes: Fully featured audio mixer with 4 mono input channels, a stereo line input, stereo Aux input and a further minijack stereo input. Each mono mic/line channel has a combo XLR/jack input with +48V phantom power switchable in pairs for the XLR inputs. Each mic/line channel has a Gain control for matching the input source and a low-cut switch to filter out rumble or handling noise from microphones. Each mono channel also has High/Mid/Low EQ controls, Aux out level, FX level and Pan control. The onboard foot-switchable DSP effects engine has 99 presets for delay, reverb and modulation effects, each of which can be adjusted using two parameter controls. An onboard Bluetooth receiver has an illuminated pairing button and independent volume control. The USB type-A port on the top panel is for playback of audio files or can be used to record the main outputs to a USB storage device or as an external audio device when connected to a laptop. Main output is served by left & right XLR, in addition to 6.3mm monitor and headphone outputs and the Aux send & stereo return loop. The CMB-series offers large console features in a more manageable format for live performers and project studio recordists.

Supplier's Notes:
Easy-to-Use Analogue Audio Mixing with Built-in Effects from Alesis

The Alto Professional TrueMix 800 FX is a portable audio mixer with built-in DSP effects that delivers all the essential features you need for home recording, livestreaming, podcasting, or performing. The TrueMix 800 FX features 16 effects including chorus, flange and an assortment of high-quality delays and reverbs. There's also a convenient Bluetooth channel for easily streaming from your personal devices. A unique feature to the TrueMix Series, the Bluetooth channel also supports feedback-free phone pairing by utilizing mix-minus technology. There are eight analogue inputs with high-headroom circuitry for minimal noise and clipping in your signal. The four Mic Input Channels offer XLR inputs that are great for connecting dynamic mics or condenser mics with 48v phantom power. These channels also have balanced 14" line inputs for connecting instruments and other line-level signals. There are also two Stereo Input Channels, each with dual balanced 14" TRS inputs. These inputs are perfect for your line level audio sources. All channels feature a two-band EQ with colour coded knobs that make it easy to dial in your perfect sound while operating in low-light situations. There are even extra knob caps included so you can fully customize the look of your TrueMix 800 FX. Connecting the TrueMix 800 FX to your computer is also lightning fast, with plug and play connectivity on Windows and macOS. The TrueMix 800 FX is a feature-packed compact audio mixer that's perfect for using on-the-go.

Flexible Output Routing

Whether you're recording a podcast, livestreaming online, or making music at home, being able to hear yourself and easily route audio is essential. The TrueMix 800 FX features a variety of output and routing options to handle any scenario. There are four headphone outputs, each with their own volume control knob. If you need to send your audio signals to another destination like an external monitor or effects unit, each channel is equipped with a send knob so you can always dial in the perfect mix. For recording, the USB output sends a copy of the main outputs to your computer, or you can connect the 2-Track in/out to an external recorder which can also be sent directly to the headphones. The TrueMix 800 FX delivers everything you need to take full control of your audio routing in any situation.
