Preparation of input channels

(1)  

Connect a microphone or line level source to each 

 

of the [INPUT] connectors (1 through 3). 

(2)  

When you connect a microphone, set the input 

 

select switch to “MIC”. When you connect a line

 

 level source, set the input select switch to “LINE”. 

(3)  

When you connect a microphone, set the 

 

microphone power supply switch appropriately.

 

When you connect a condenser microphone that 

 

re48 V phantom power, set the switch to “P48”. 

 

When you connect a condenser microphone that 

 

requires T-12 power (A-B 12 V) such as Sennheiser 

 

416T, set the switch to “P48”. When you connect a 

 

dynamic microphone, set the switch to “DM”.

(1)  

Connect an external audio device such as a 

 

recorder to the [MAIN OUT] connectors (L and R). 

(2)  

Set the output level switch appropriately depending 

 

on the device connected.

 

You can select from +4 dBu, 0 dBu, -20 dBu and -60 

 

dBu.

(3)  

To connect a -10 dBV unbalanced line level device, 

 

use the [TAPE OUT] connector (stereo mini jack).   

 

The nominal output level of this connector is fixed  

 

to -10 dBV.

You can turn on the unit by setting the [POWER] switch 

on the front panel to “INT” (upper position) or “EXT” (lower 

position). When you operate the unit on internal battery 

power, set the switch to “INT”. 

When you operate the unit on external power, set it to 

“EXT”. When you turn on the unit for the first time, the 

display shows the stereo VU meters as shown below.  

When you operate the unit on (internal on external) bat-

tery power, confirm that the battery power is sufficient by 

checking the battery indicator on the meter display.

You can check the power voltage of the battery power 

source from the system status display (see page 20).  

Battery indicator

<Memo>: 

If you do not need T12 (A-B 12 V) power 

supply capability, you can disable this capability from 

the input status display. By default, it is enabled. See 

page 16 for details.  

Preparation of output channels

Preparation of metering

(1)  

Select stereo or mono metering.

 

When the unit is shipped, the display is set to stereo   

 

VU and peak metering.

 

You can change it to L or R channel mono metering (see 

 

page 15 for details).

(2)    

Adjust the display brightness if required.

 

 

When the unit is shipped, the display brightness is set 

 

 

to “Level 3”.

 

 

You can change it to the optimum brightness according 

 

 

to the circumstance. See page 14 for details.

<Memo>: 

Using the meter status display, you can 

disable or enable the peak meter function, select 

the VU meter reference level, and select the “OVR” 

indicator lighting level (see page 19 for details).
