Laney Iommi TI15-112, Operating Instructions Manual

REAR PANEL CONTROLS

FX RETURN: 

1/4" mono jack socket for the connection of the output of an external FX unit.  This can also be used as a slave 

in for the power amp.   As the FX Loop is an insert type,  this will mute the preamp signal.

FX LOOP SWITCH: 

Selects the FX Loop mode of operation:  

!

Bypass  - Removes the FX Loop from the signal path.

!

0 dBu - For connection of FX units with a 0dBu nominal output level.

!

-10dBu - For connection of FX units with a -10dBu nominal output level.   As this is intended for devices with a lower 

output level,  this switch increases the gain of the FX Loop by 10dB.

FX SEND: 

1/4" mono jack socket for connection to the input of an external FX unit.   This can also be used as a line out for 

connection to another power amp slave input or for recording.

FOOTSWITCH SOCKET:

 Use a mono tip-switched footswitch (such as the Laney FS1) to enable the Pre-Boost circuit. 

Note: The Pre-Boost switch on the front panel must be set to O, in order to use the footswitch.

LOUDSPEAKER CONNECTIONS 

Two 1/4" mono jack sockets are provided for the connection of either an 8 Ohm or 

16 Ohm loudspeaker cabinet. Do not use more than one socket at a time. When using the internal loudspeaker, ensure it is 
connected to the 8 Ohm socket. Mismatching your speaker impedance will reduce the performance of your amplifier, and in 
extreme cases may damage the unit.  Never operate any tube amplifier without a load connected: serious irreparable 
damage may occur.
