[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.  

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]

 

A slate 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).

<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.

<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)

MS decoded signals are output.

AUX

Signals input to the [AUX IN] connector.

L-R

R component of MS is output in mono. 

ON

OFF

The limiter function is enabled. Each of the left and right 

limiters works independently. 

The limiter function is disabled (the limiter circuit is by-

passed).  

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.

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).

This switch selects the signal monitored by the 

 

headphones connected to the [PHONE] jacks (1/4-inch   

 

and mini).

“LIM” icon

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.

ON

By turning the control right from the Off 

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).

OFF

 (leftmost position)

The HPF circuit is bypassed.
