AMX-100MKII/100FXMKII compact mixer with digital ▲LTO multi-effect is just one of the many
products that a talented, multinational ▲LTO Team of Audio Engineers and Musicians have developed
with their great passion for music. AMX-100MKII/100FXMKII is a remarkable compact mixing desk that
doesn't find many equals in the market today. With enough microphone and Line-level inputs for
serious, small live performances, AMX-100MKII/100FXMKII also includes a 24 Bit digital Multi-effect
with 16 Factory Presets and 16 variations for every preset, for a total of 256 different digital effects.
There is a 3-band EQ on all input channels and separate Main Mix and Control Room outputs for
Multi-zone operation with different volume settings. The 2TK input usually used for Tape of CD sources
even comes with its own volume control and this feature is hard to find in a mixer of this size.
Use it forsmall Gigs, for Computer Audio. AMX-100MKII/100FX MKII is a flexible tool for Multimedia
presentations. FEATURES as following:
2 MIC input channels with gold plated XLRs and balanced Line input;
4 stereo input channels with balanced TRS jacks;
Ultra-low noise discrete MIC pre-amps with +48V Phantom power;
Extremely high headroom offering extra dynamic range;
Balanced inputs for highest signal integrity and low-noise operation;
Warm, natural 3-band EQ on each channel;
AUX send switch-able to PRE/POST fader;
2 AUX returns for additional functionality;
Peak LED on each channel;
2-Track inputs with level control assignable to main mix, control room /headphone outputs;
Highly accurate 4-segment bar graph meters;
24 bit digital effects processor with 256 effects (16 presets 16 variations).(for AMX-100FXMKII only);
Effect on/off with MUTE switch or an optional footswitch.
