FM-4
portable mixer
Equipped with a high-grade transformer, 4-channel inputs, 2-channel outputs, and a wealth of sub-outputs, this portable mixer has a Hi-Mid 2-band EQ and limiter for a variety of applications.
Features
Lightweight and robust design using hard aluminum and highly resistant parts
The housing is made of hard aluminum and the fader knobs are machined from aluminum to achieve high durability while reducing weight.
Faders use conductive plastic conductors and metal shafts for superior durability.
Equipped with a 2-band EQ from HI (10 kHz)-MID (200 Hz to 8 kHz). Wide range of sound quality adjustment is possible.
Seamlessly variable PAN enables precise localization adjustment.
The TRIM, HPF, and MASTER fader knobs are pop-up type so that they do not get in the way when operating the CH fader.
Two headphone outputs (50mW), Φ6.35mm and Φ3.5mm (side), are provided for highly flexible monitoring using the PFL and selector.
PEAK indicator on each channel indicates PEAK detection status in two levels: green (+8dB) and red (+17dB).
Built-in 1kHz slate tone and slate microphone.
Highly visible level meter with OLED display
The OLED display can also be switched between STEREO, MONO, and PFL.
The OLED display can also show remaining battery level, CH setting status (MIC-LINE, phantom on/off, etc.), limiter value, etc.
High quality head amp with originally designed transformer
● 4-channel input compatible with mic/line using a high-grade transformer of original design provides excellent noise immunity.
Phantom 48V and T12V can be supplied to the microphone input.
Mic gain of -30 to -70dBu and line gain of -20 to +4dBu are provided for a wide range of recording applications.
Equipped with a dedicated monitor return input for checking audio from VTRs, cameras, and other sources.
AUX input can be mixed to stereo bus in addition to monitor, and cascade connection is also supported.
Abundant auxiliary outputs in addition to transformer-equipped main outputs
The main outputs are also equipped with an originally designed high-grade transformer.
Main and sub outputs (XLR-3P/electronically balanced) can be switched to direct output (POST fader).
Main and sub outputs can be switched between +4/0/-10/-60dBu reference output levels.
Auxiliary outputs include TAPE OUT (-10dBV) and AUX OUT1-2 (-10/-60dBV switchable, channel selectable). Flexible support for various environments.
Headphone output (Φ3.5mm stereo phone) is also provided on the side. The headphone output can be used simultaneously with the headphone jack on the front panel.
Output level may be reduced when used simultaneously.
The main outputs are equipped with a limiter that can be linked to the L/R outputs, and the threshold (+6/+12) and ratio (3:1/5:1) can be set.
The internal power supply consists of eight AA (alkaline or nickel-metal hydride) batteries in a battery case (EX-BP2).
The unit is equipped with a DC input (XLR 4-pin) for external power supply, and an external battery or optional AC adapter* can be used.
*Use the dedicated AC adapter AD-15C (standard price including tax: ¥36,750).
Equipped with a DC-OUT for supplying power to an external wireless raver or other devices.
