Connecting Other Equipment; Turning The Power On/Off - Roland SP-404 Owner's Manual

Before You Start

Connecting Other Equipment

Refer to the illustration, and make connections in the order given
below.
Audio Set / Amplified Speaker etc.
AC Adaptor
Stereo Headphones
1.
Turn off the power of all devices before you make
connections.
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 included AC adaptor to the DC IN jack.
Alternatively, you can power the SP-404 on six AA batteries.
If you're running the SP-404 on batteries, this step is not
necessary.
Installing the Batteries
Remove the battery compartment cover located on the bottom
of the SP-404, and insert the batteries in the correct polarity
(direction) as marked on the bottom of the unit. Then close the
cover securely.
When the remaining battery capacity decreases, the display
illumination will remain lit, and the dot in the lower right of the
display will alternately blink at short and long intervals. If the
batteries run down completely, "Lo" appears in the display and
no further operations will be possible. If this occurs, replace the
batteries immediately.
The contents of the SP-404's internal memory are preserved
even if the batteries run down.
When the remaining battery capacity decreases, the sound
may be distorted when the VOLUME knob is in certain
positions. If this occurs, replace the batteries.
When turning the unit upside-down, get a bunch of
newspapers or magazines, and place them under the four
corners or at both ends to prevent damage to the buttons
and controls. Also, you should try to orient the unit so no
buttons or controls get damaged.
When turning the unit upside-down, handle with care to
avoid dropping it, or allowing it to fall or tip over.

Microphone
3.
Connect the LINE OUT jacks to your audio system or amp. If
you're using headphones, connect them to the PHONES
jack.
If you want to record a sample (p. 14, p. 23), connect your CD
player or other audio source to the LINE IN jacks, or connect a
mic to the MIC IN jack. (If you will be using the SP-404's
internal mic, this is not necessary.)
When connection cables with resistors are used, the volume
level of equipment connected to the inputs (LINE IN, MIC IN)
may be low. If this happens, use connection cables that do not
contain resistors, such as those from the Roland PCS series.
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.
4.
Connect the AC adaptor to an AC power outlet.

Turning the Power On/Off

Turning the Power On
Once the connections have been completed, turn on power to
your various devices in the order specified. By turning on
devices in the wrong order, you risk causing malfunction and/
or damage to speakers and other devices.
1.
Turn the SP-404's VOLUME knob all the way to the left to
minimize the volume.
2.
Minimize the volume of the connected amp or audio
system.
3.
Turn the SP-404's POWER switch to the ON position.
Always make sure to have the volume level turned down before
switching on power. Even with the volume all the way down,
you may still hear some sound when the power is switched on,
but this is normal, and does not indicate a malfunction.
4.
Turn on the power of the connected amp or audio system.
5.
While striking the SP-404's pads to produce sound,
gradually raise the VOLUME knob to adjust the volume.
Also, adjust the connected amp or audio system to the
appropriate volume level.
Turning the Power Off
1.
Minimize the volume of the SP-404 and the connected amp
or audio system.
2.
Turn off the power of the amp or audio system.
3.
Turn off the power of the SP-404.
