Preparing to use the SI-24
Turning the power on/off
■ Turning the power on
1. Use the rear panel POWER switch to turn on the power of the SI-24.
When the power is turned on, the power indicator will light.
2. Turn on the power of your audio system.
3. Raise the volume of your audio system to an appropriate level.
■ Turning the power off
1. Turn off the power of your audio system.
2. Use the rear panel POWER switch to turn off the power of the SI-24.
When the power is turned off, the power indicator will go out.
Using phantom power
Turn phantom power on if you connect a condenser mic that requires phantom
power. When phantom power is turned on, phantom power will be supplied to the
XLR type INPUT jacks.
• Always turn the phantom power off when connecting any device other than
condenser microphones that require phantom power. You risk causing damage if
you mistakenly supply phantom power to dynamic microphones, audio playback
devices, or other devices that don’t require such power. Be sure to check the
specifications of any microphone you intend to use by referring to the manual that
came with it. (This instrument’s phantom power: 15 V DC, 10 mA Max)
• The SI-24 is able to supply phantom power to condenser mics for which the 15V
current is no more than 10 mA. Also, if you are using phantom power with multiple
INPUT jacks, you must ensure that the total current does not exceed 80mA. We
cannot guarantee operation for condenser mics that require more electrical power
than this. In such cases, you will need to use a phantom power supply device.
• Phantom power is not supplied to the phone type INPUT jacks on the rear panel. If
you need phantom power, use the XLR type INPUT jacks on the top panel.
• To prevent hazard or damage, ensure hat only microphone cables and microphones
designed to IEC-268-15A are connected.
• Afin d'eviter tout resque ou dommage, ne brancher que des cables de microphone
et des microphones conformes a la norme IEC-268-15A.
1. Hold down [SHIFT], and press the [CH SELECT] button of the number
corresponding to the INPUT jack for which you want to switch phantom power on.
❍ Number of [CH SELECT] buttons (1-8) corresponds to same numbered input
jacks (XLR).
❍ While you hold down [SHIFT] , the peak indicators and [CH SELECT] will
show the phantom power on/off status.
Indicator lit : phantom power on
Indicator dark : phantom power off
• Once the connections have
been completed (p. 14), 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.
• This unit is equipped with a
protection circuit. A brief
interval (a few seconds) after
power up is required before
the unit will operate normally.
