1.POWER - Switches the RU-N2N on-off.

2.INPUT - Use either this jack or the rear panel IN jack {8} to input your bass signal.

3.MUTE - Disconnects the OUT 2 jack audio output as indicated by the MUTE LED, useful for silent bass tuning. MUTE can be activated from either the front panel MUTE button or a MUTE footswitch (optional), but MUTE can only be deactivated by the same switch that activated it.

4.TUNING LEDs - These 20 LEDs indicate the degree of flatness or sharpness of the played note compared to the displayed note {7} in 5 cent intervals. The RU-N2N puts on a “light show” after 1 minute of no input.

5.SWR BADGE - Lights brightly to indicate when the played note is “in tune” to the displayed note {7}.

6.CALIBRATION MODE and FLAT NOTE DISPLAY -

Calibration Mode: Adjusts the A4 reference frequency (default 440Hz) from 438Hz to 445Hz. Press and hold CAL to activate Calibration Mode. While the calibration frequency is displayed, press CAL repeatedly to change the reference frequency in 1Hz steps. Calibration Mode cancels automatically.

Flat Note Display: Press CAL to display flats, rather than sharps (“Ab” instead of “G#”), as indicated by the LED. Press CAL again to cancel.

7.NOTE DISPLAY - Indicates the closest note to the played note (see FLAT NOTE DISPLAY above).

8.IN - Alternate input jack. This jack is disabled automatically if a plug is inserted into the front panel INPUT jack {2}.

9.OUT 1 and OUT 2 - Connect either of these output jacks to your amplifier input: OUT 1 is always active. OUT 2 can be disabled by the MUTE‑switch {3}.

10.MUTE FOOTSWITCH - Connect a standard latch-type footswitch to enable remote audio muting, see MUTE {3}. (Mute is active when the footswitch is in the “closed” position.)

11.MAIN POWER INPUT - Connect the included power cord to a grounded AC outlet in accordance with the voltage and frequency ratings specified on the rear panel of your RU-N2N.

12.MAIN FUSE - Protects the unit from electrical faults. Replace a blown fuse only with the type specified on the rear panel of your RU-N2N.
