Depending on the position, the rolloff frequency changes between 40 Hz and 300 Hz (-12 dB/oct). 12. 16. 13. 14. 17. ON OFF 18. The limiter parameters are factory-preset as shown below. You can change the threshold level and ratio from the output status display (see page 18). ·Attacktime:Approximately5milliseconds(fixed) ·Releasetime:Approximately200milliseconds(fixed) · Threshold: +12 dB (can be changed to +6 dB) · Ratio: 5:1 (can be changed to 3:1) <Factory preset values> Input trim controls (1 through 3) Each control adjusts the input gain of the corresponding input channel. When the input select switch is set to MIC, you can adjust the gain between -70 dBu and -30 dBu. When the input select switch is set to LINE, you can adjust the gain between -20 dBu and +4 dBu. It is recommend to adjust the control so that the PEAK indicator does not light in red at the maximum input level. Channel faders (1 through 3) Each fader controls the signal level sent to the stereo buss. The scale position in orange shows the reference position. 19. 11 Left side panel section 1. [INPUT] connector (1 through 3) Each connector is used to connect an external audio device or microphone. Connector: XLR-3-31 type 1 2 3 GND HOT COLD 5. Microphone power supply switches (T12 / DM /P48) Each switch sets whether or not supplying the microphone power. T12 or AB power supply mode. A 12 V power is supplied to the hot terminal of the [INPUT] connector. T12 <Memo>: If you do not need T12 power supply, you can disable the power supply via the input status display (see page 16 for details). A 48 V power is supplied to the hot and cold terminals of the [INPUT] connector. 2. [AUX IN] connector Used to connect a mixer or audio device. Not only you can monitor the input signal of this connector, you can send the signal to the stereo buss to mix with the main input signals (selectable with the [TO ST BUSS] switch). Connector: XLR-5-51 type 1 2 4 3 5 GND Lch HOT Lch COLD Rch HOT Rch COLD DM P48 6. [DC IN 10-24V] connector Used to connect the supplied AC adaptor (or an external battery). Connector: XLR-4-32 type (male) 1 2 4 3 GND NC DC 10-24V NC 3. [TO ST BUSS] switch (ON / OFF) This switch selects whether or not the input signal from the [AUX IN] connector is sent to the stereo buss. When the switch is set to OFF, the [AUX IN] signal is not sent to the stereo buss. Regardless of the switch setting, you can monitor the [AUX IN] signal via headphones. Input select switches (LINE / MIC) Each switch should be set appropriately according to the input signal source. LINE You should set the switch to LINE when a line-level source is connected to the input connector. When it is set to LINE, the microphone power supply is automatically turned off regardless of its setting. You should set the switch to MIC when a microphone is connected to the input connector. You can supply the microphone power when connecting a condenser microphone (see "Microphone power supply switch" below). 7. [DC OUT 7. 2-24V] connector This connector outputs power at DC 7. 2 ~ 24 V / 0. 5 A for a wireless receiver, etc. [. . . ] You may also have additional rights depending on the state in which the Fostex product was purchased.
