Insert the SmartMedia card into
the SmartMedia card slot on the
front panel of the MRS-4, as
described on page 5. 

3.

Set the [POWER] switch of the
MRS-4 to ON. 

The MRS-4 starts up.

Connections 

When a line level signal such as that from a CD player or rhythm machine 
is connected to the AUX IN [L/MONO]/[R] jacks, it will be output from 
the MASTER [L]/[R] jacks together with the mixed playback signal from 
the tracks of the MRS-4. For a stereo device, use both the [L/MONO] and 
[R] jacks. For a mono device, use only the [L/MONO] jack. 

Connect the monitor system 
or master recorder to the 
MASTER [L]/[R] jacks. 

To power the MRS-4 from an 
AC outlet, be sure to use only 
the AC adapter ZOOM AD-
0006 (available separately). 
Using another kind of AC 
adapter may result in damage.

To  synchronize operation of 
the recorder section of the 
MRS-4 with another MIDI 
device, connect the [MIDI 
OUT] connector of the MRS-
4 to the MIDI IN connector 
of the other device

To  monitor with headphones, 
plug them into the [PHONES] 
jack. This jack carries the 
same signal as the MASTER 
[L]/[R] jacks

Headphones

Multi-effect such 
as 505II 

Mic

Guitar 

Monitor system 

Master recorder 

Rhythm machine, 
MIDI sequencer or 
other MIDI device

AC adapter

CD player or other external source component

Loop the cable of the AC
adapter around the hook as
shown in the diagram before
connecting it to the [DC 9V]
jack. This will prevent the plug
from being pulled out if the
cable is accidentally pulled.
