Fostex FM-3 owner manual Monitor select switch, Status / Edit key, 12 /4-inch Phones jack, Mic

10.Monitor select switch

This switch selects the signal monitored by the headphones connected to the [PHONE] jacks (1/4-inch and mini).

AUX	Signals input to the [AUX IN] connector.
RTN	Signals input to the [RTN] connector.
L	Asignal output from the [MAIN OUT L] connector in mono.
ST	Signals output from the [MAIN OUT L and R] connectors in
	stereo.
R	Asignal output from the [MAIN OUT R] connector in mono.
L+R	Signals output from the [MAIN OUT L and R] connectors
	in mono (L component of MS).
MS	MS decoded signals are output.
L-R	R component of MS is output in mono.

11.[STATUS] / [EDIT] key

Holding down this key for a second or more enters the status mode. In this mode, you can switch among status display pages as well as you can edit parameters (see page 15).

In the brightness adjustment mode, meter selection mode or status display mode, this key acts as the [EDIT] key (see page 15). Pressing this key briefly exits the current mode while pressing this key for a second or more enters or exits the parameter editing mode.

12.1/4-inch [PHONES] jack

You can connect stereo headphones with the 1/4-inch plug for monitoring.

13.Headphones level control

This control is used to adjust the output level of both the 1/4-inch and mini [PHONES] jacks.

14.[LIMITER] switch (ON, OFF, LINK)

This switch enables or disables the limiter function. The limiter can work individually or in link, as described below.

The limiter circuit is inserted after the MASTER fader.

LINK	The limiter function is enabled with the left and right
	channels linked. If either of left and right channel signals
	exceeds the threshold, both the left and right channel
	limiters work in the same way.
ON	The limiter function is enabled. Each of the left and right
	limiters works independently.
OFF	The limiter function is disabled (the limiter circuit is by-
	passed).

The limiter parameters are factory-preset as shown be- low.

You can change the threshold level and ratio from the output status display (see page 18).

<Factory preset values>

•Attack time:Approximately 5 milliseconds (fixed)

•Release time:Approximately 200 milliseconds (fixed)

•Threshold: +12 dB (can be changed to +6 dB)

•Ratio: 5:1 (can be changed to 3:1)

<Memo>: When you select the [LIMITER] switch to ON or LINK, the meter display shows “LIM” (pointed by arrows below). When the limiter is working, “LIM” flashes. The following shows display examples of the stereo meter display.

15.[MASTER] faders (L and R)

These faders control stereo left and right buss output levels. The scale position in orange shows the reference position. These faders are push-locked type. Pressing a fader puts it to the up position. Pressing it again puts it to the down position (flat position).

16.[MIC]

Aslate microphone is built in. While holding down the [SLATE] switch to the “MIC” position, the slate microphone is active and the signal from the microphone is sent to the stereo buss.

17.HPF controls (1 through 3)

Each control sets the high pass filter function.

These controls are push-locked type. Pressing a control puts it to the up position. Pressing it again puts it to the down position (flat position).

OFF	The HPF circuit is bypassed.
(leftmost position)
	By turning the control right from the Off
ON	position, it clicks and the HPF circuit gets
	active. Depending on the position, the roll-
	off frequency changes between 40 Hz and
	300 Hz (-12 dB/oct).

18.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. These controls are push-locked type. Pressing a control puts it to the up position. Pressing it again puts it to the down position (flat position).

19.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.
