Roland SPD-S Owner's Manual page 21

While referring to the illustration on the previous page, take the following steps:
1. Before making a connection, power all the devices off.
To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power
on all devices before making any connections.
2. Connect the supplied AC adaptor to the AC Adaptor jack.
To prevent the inadvertent disruption of power to your unit (should the plug be pulled out accidentally), and to avoid
applying undue stress to the AC adaptor jack, anchor the power cord using the cord hook, as shown on the previous page.
3. Connect an audio system or an amplifier to the OUTPUT jacks. To use headphones, connect them to the
PHONES jack.
To sample (p. 25, p. 52), connect an input device (like a CD player or a microphone) to the INPUT jacks.
4. Insert the plug of the AC adaptor into a power outlet.
Q: The volume level of the instrument connected to INPUT jacks is too low.
A: Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
Howling could be produced depending on the location of microphones relative to speakers. This can be remedied by:
1. Changing the orientation of the microphone(s).
2. Relocating microphone(s) at a greater distance from speakers.
3. Lowering volume levels.
