Functions

1. Channel Bass control: ±15dB

2. Channel Treble control: ±15dB

3. Channel Level control: Volume level should be lower than the master level. This control acts as a preamp. If you are using a device that has a volume output control, you will need to match levels by adjusting the level controls on each unit.

4. Line/High impedance 1/4″TS input: This input may be used as either a high-impedance microphone input or for line-level devices such as a cassette player, CD player, video projector, or laptop. Will also allow connection from an electric guitar, bass, or keyboard. It is a two conductor input with an impedance of 10K ohms.

5. Microphone/Low impedance XLR input: Connect balanced low impedance microphones with an input impedance of 1K ohms. PIN 1 = shield, PIN 2 = positive (hot), PIN 3 = negative (cold)
   WARNING: When using condenser microphones, make sure that Phantom power (48V) is switched on (see item 24).

6. Channel Pan: Used to adjust left to right balance.

7. Channel Echo: Controls the amount of echo added to the input signals.

8. Channel 4 RCA Line In: Used to connect line level sources such as CD players, cassette decks, laptops, MP3 players, etc. Mono audio sources can be connected using an RCA “Y” cable connector.

9. RCA Record Out: Sends signal to a recording device or any other line level device.

10. Balanced 1/4″TRS Line Out: Sends the music signal to another amplifier, a powered subwoofer, powered speakers, monitors, or any other external device.

11. SD card slot: Inserting an SD card will set the RPM48S to SD mode and it will automatically begin to play music.

Troubleshooting

1. Make sure the unit is plugged in and the power switch is in the ON position.

3. Check and replace the fuse if necessary. See fuse replacement diagram on the next page.

No sound|

1. Check that all appropriate cables are plugged in correctly.
2. Check the Master volume settings.
3. Check the individual level control of each channel as well as the MP3 volume control and Line level volume controls.
4. Be sure your microphone(s) is on

Noise|

1. Turn down the channel levels one by one. If you don’t hear the sound, then the problem is either with the channel or whatever device is plugged into it.
2. Unplug the device(s) to see if the sound disappears.
3. Make sure you are using the proper cables. For W cables, there are 3 types: instrument, TS (unbalanced), and TRS (balanced). Check the requirements of the connected gear and make sure you are using the appropriate cable.

Buzzing sound| Make sure you are using a proper cable. For 1/4″ cables, there are 3 types: instrument, TS (unbalanced), and TRS (balanced). Check the requirements of the connected gear and make sure you are using the appropriate cable.
