Quick Setup Guide

QUICK SETUP GUIDE

In case you simply cannot wait to experience the performance of your new 
M23, the following QUICK SETUP GUIDE is recommended to help you get 
started.

Ensure that the M23 is unplugged before making any connections. It is 
also advisable to power-down or unplug all associated components while 
making or breaking any signal or AC power connections. Set the external 
source's volume control to minimum level. External source can be a 
preamplifier, processor, amplifier or any applicable device.

Set SELECT switch to BALANCED or SINGLE-ENDED. It is important that 
the selection for AUDIO INPUT must be the same for both L (left) and R 
(right) channels.  

Connect the analog audio output of your external source to the M23 
rear panel’s BALANCED or SINGLE-ENDED audio input. 

Connect your speakers to the LEFT and RIGHT SPEAKERS terminals of 
M23.  

Ensure that the supplied power cord’s female connector end is firmly 
secured to M23’s AC Mains input socket and the male plug connected 
to the mains power source.

Power up the external source ahead of the M23.  

Set to ON the rear panel POWER switch of M23. The M23 goes to 
standby mode as shown by the amber status condition of the Power 
indicator. 

Press 

o

 (Standby) button for the M23 to be powered up from standby 

mode. The Power indicator will turn from amber to bright/white color. 
The M23 is ready for operation.

Adjust the external source’s volume control according to desired 
listening level. 

SAVE THE PACKAGING

Please save the box and all of the packaging in which your M23 arrived. 
Should you move or otherwise need to transport your M23, this is by far the 
safest container in which to do so. We’ve seen too many otherwise perfect 
components damaged in transit for lack of a proper shipping carton, so 
please: Save that box!

NOTES ON INSTALLATION

• 

Your unit should be placed on a firm, level surface. 

• 

Avoid placing the unit inside a closed cabinet that is not well ventilated 
as this may compromise the M23’s performance and reliability.

• 

Avoid placing the unit in direct sunlight or near sources of heat and 
damp. 

• 

Allow adequate ventilation. 

• 

Do not place the unit on a soft surface like a carpet.  

• 

For best performance, use quality speaker leads of 16-gauge (1.5mm

2

thickness or more.  

• 

If the unit is not going to be used for some time, disconnect the plug 
from the mains power source.

• 

Use a dry cloth for cleaning.

DO NOT REMOVE THE COVER; THERE ARE NO USER-SERVICEABLE 
PARTS INSIDE.

BARE WIRES AND PIN CONNECTORS

WARNING:

 The terminals marked with this symbol 

are hazardous live.  External wiring connected to these 
terminals requires installation by an instructed person or 
the use of ready-made leads or cords.

Bare wires and pin sockets should be inserted into the hole in the shaft of 
the terminal. Unscrew the speaker terminal’s bushing until the hole in the 
screw shaft is revealed. Insert the pin or bare cable end into the hole and 
secure the cable by tightening down the terminal’s bushing. Ensure bare 
wire from the speaker cables does not touch the back panel or another 
socket. Ensure that there is only 1/2” (1cm) of bare cable or pin and no loose 
strands of speakers wire.

FEET INSTALLATION

The supplied magnetic feet can be easily installed by aligning and attaching 
them to their corresponding foot shoe.  Refer to the illustration below.
