MG12/4FX NEW MG16/6FX If the idea of having some of the finest effects available built right into the console appeals to you, then consider the effect-enabled models: the MG12/4FX or MG16/6FX. You get the same type of versatile mixing power and superior audio performance that is provided by the non-effect models, plus leading Yamaha signal processing quality all in one console. 　 12 or 16 Input Channels The MG12/4FX feature a total of 12 input channels: four mono microphone/line inputs and four stereo line inputs, two of which offer mono microphone input capability. The MG16/6FX feature eight mono microphone/line inputs and four stereo line inputs, two with mono microphone input capability. Gain trim covers a wide -60dB ~ -16dB range for microphone input, and -34dB ~ +10dB for line input. A Variety of Input Connectors Balanced XLR connectors are provided on all four or eight mono inputs and two of the stereo inputs (a total of six XLR connectors on the MG12/4FX model, and ten on the MG16/6FX), in addition to phone jack connectors. Two of the stereo channels can accept mono microphone input either via the XLR or phone jack connectors. The remaining two stereo inputs feature both phone jack and pin jack inputs for broad connectivity. A separate stereo 2TR input with pinjack connectors is provided for independent input of signals from CD players or similar sources. Six or Ten Low-noise, High-precision Mic Preamps Six high-performance head amplifiers in the 12-channel modes or ten in the 16-channel models will bring out the best in any dynamic or condenser microphone. Phantom Power All high-performance mic preamps in these consoles feature switchable phantom power for studio condenser microphones. A single switch turns phantom power on or off for all channels. 　 Insert I/O Mono input channels feature insert I/O patch points so you can add compressors or EQ for vocals, a noise gate on a guitar channel, or other extra signal processing to individual channels as required. 3-band Channel EQ & HPF (MG12/4FX) Smooth, "musical-response" 3-band equalizers are provided on the MG12/4FX input channels. All mono microphone input channels also feature a switchable high-pass filter that can be used to cut out unwanted low-frequency noise. Versatile EQ for Effective Sound Shaping (MG16/6FX) Mono channels feature 3-band equalizers with HIGH (10 kHz), LOW (100 Hz), and MID (250 Hz ~ 5 kHz mid-sweep) bands. High-pass filters are also provided on all microphone inputs. Stereo channels have 4-band equalizers with HIGH (10 kHz shelving), HI MID (3 kHz peaking), LOW MID (800 Hz peaking), and LOW (100 Hz shelving) bands. Four or Six Buses (Stereo and Group) In addition to the main stereo bus, the MG12/4FX feature a stereo group bus and outputs that can be used for convenient channel grouping. The MG16/6FX has an additional two group busses for a total of six buses. Stereo and group bus assign switches are located above each channel fader. You could, for example, mix your instrument sources to the stereo buss while creating separate groups for the main vocal and chorus channels ... or any bus configuration you need for your application.
