Introducing the R-4
fig.panel-1.eps_50
Hold switch [HOLD]
By selecting the
HOLD ON
position, you can disable the panel buttons so that unwanted operations will not
occur if a button is pressed accidentally.
However, even if this switch is set to HOLD ON, the
phantom power switches
,
limiter switch ,
input level select switches
,
Input level knobs
, and
Monitor level knob
will still be
operable.
Phantom power switches [PHANTOM POWER]
These switch the phantom power on/off for the XLR type connectors of the combo input jacks located on
the right panel. Since separate switches are provided for channels 1/2 and channels 3/4, you can turn
phantom power on/off separately for these channels.

* Always turn the phantom power off when connecting any device other than
condenser microphones that require phantom power. You risk causing damage
if you mistakenly supply phantom power to dynamic microphones, audio
playback devices, or other devices that don’t require such power. Be sure to
check the specifications of any microphone you intend to use by referring to
the manual that came with it.
This instrument’s phantom power: 48 V DC, 8 mA Max
(total of all channels must be 25 mA or less)
Limiter switch [LIMITER]
This is an on/off switch for an input level limiter in the analog circuitry.
When the input level is too high, the limiter compresses the input level appropriately to prevent distortion.
The limiter switch turns limiting on/off for all channels 1–4 together. However, the input level is detected
separately for each channel. You cannot turn the limiter on/off separately for each channel.
