Introducing the R-4 Pro

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 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 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.

* Keep the phantom power turned off for any device other than condenser microphones that require phantom power.
You risk causing damage if you mistakenly supply phantom power to dynamic microphones 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 can be set to operate each channel independently or use channels 1-2 and 3-4 as pairs (linked).
