This switch supplies +48 V phantom power to 
XLR and TRS phone compatible INPUT jacks 1 
and 2 (

3

). Note that phantom power will not 

be supplied if you have connected an external 
device to the INPUT 1 and 2 TRS phone jacks 
(

3

). Turn this switch on if you are connecting a 

condenser microphone that requires external 
+48 V power to INPUT jack 1 or 2 (

3

). When 

the switch is turned on, the switch indicator 
lights up.

• Be sure to turn this switch off if you 

connect a device that does not require 
an external power supply to the INPUT 
1 or 2 XLR jack. Otherwise, phantom 
power will be supplied to the device, 
possibly causing damage to the 
device.

• If you connect a device that requires 

an external power supply, first connect 
the device to an XLR connector, then 
turn on the phantom power.

• When phantom power is turned on, 

power will be supplied to both INPUT 
jacks 1 and 2.

• Phantom power is not supplied to TRS 

phone connectors.

If the [HI-Z/LINE/MIC] switch (

2

) is 

set to HI-Z, phantom power is not sup-
plied to INPUT jack 1 (

3

).

This switch enables you to select high-imped-
ance input, mic input, or line input for XLR and 
TRS phone compatible INPUT jacks 1 and 2 
(

3

).

HI-Z:

Use this setting to connect a high-
impedance musical instrument, such 
as a guitar with passive pickups or a 
bass guitar.

LINE:

Use this setting to connect a line-level 
instrument, such as a synthesizer, key-
board, or audio equipment.

MIC:

Use this setting to connect a mic-level 
device.

Select HI-Z, LINE, or MIC for INPUT 
jack 1. Select LINE or MIC for INPUT 
jack 2.

When the [HI-Z/LINE/MIC] switch is 
set to HI-Z, phantom power is not sup-
plied to INPUT jack 1 (

3

).

These balanced input jacks accept both XLR-3-
31 and TRS phone (1/4") plugs and can be used 
for high-impedance, line or mic inputs. You can 
also connect musical instruments with unbal-
anced outputs, such as a synthesizer or rhythm 
machine. Setting the [HI-Z/LINE/MIC] switch 
(

2

) appropriately enables you to connect a 

high-impedance instrument, line-out instru-
ment or microphone to INPUT jack 1. Setting 
the [LINE/MIC] switch (

2

) appropriately 

enables you to connect a line-out instrument or 
microphone to INPUT jack 2.

Nominal input levels:

MIC:

–60 dBu to –16 dBu

LINE:

–34 dBu to +10 dBu
