MIDI
AUDIO ROUTER & SWITCHER - VERS. 4.0
 |
|
LS42 is a multiple MIDI switcher which incorporates
the functions of 4 audio loopers
(suitable for pedal effects commutation) and
2 pure switches
for the on/off management of remote control devices (for example the change
of amplifiers channel, multieffects by-pass etc.)
LS42 functioning principle is based on the use of ADVANCETUBETECH exclusive
technology which permits a SOFT function
absolutely “click-less” during commutation: this guarantees an absolute
TRUEBYPASS
transparency, thanks to the use of very high quality
passive components (such as ampoule REED relays and resistors) as regard the
circuits crossed by audio signal.
SOFT FUNCTION
LS42 soft function, selectable and memorizable
independently on each memory location, permits to carry out soft commutations,
without
any kind of insertion noise (click). This action,
besides the absolute silent commutation, inserts and disconnects the device
managed through
a short ascent/descent gradual slope (70/100mS) which creates a “cross-fade”
effect, making the input of the selected loop more pleasant
(for example the connection of a pedal effect).
MIDI MANAGEMENT
LS42 is managed via MIDI through a pedal, a sequencer
or any MIDI device able to send messages
of PROGRAM CHANGE
/ CONTROL CHANGE
according to standard MIDI.
It consist of one MIDI IN and one MIDI THRU and, thanks to the 7 poles connector,
can be powered through phantom power.
Memorization on 128 memory locations.
Programming of MIDI receiving channel for PROGRAM CHANGE ( from 1 to 16 or OMNI
).
Programming of MIDI receiving channel for CONTROL CHANGE
on channels 15 (no-soft) or 16 (soft).
CASCADE CONNECTION
It is possible to connect more than one LS42
by MIDI IN and THRU connections for example for the management of a pedal effects
set
composed by more than 4 elements.
As regard PROGRAM CHANGE there are no limits in choosing numbers for cascade
connection.
As regard CONTROL CHANGE there is a limit of 4 units.

FRONT
|
The push buttons and leds placed
on the front panel permit an easy programmation of the tool on 128 memory
locations.MIDI setup allows to choose the reception channel (from 01 to
16) or the OMNI mode. It is possible to set out the SOFT or NO-SOFT mode independently from each one of the 4 loops. |
|
BACK |
On the back side, the arrows route indicates
the chain of the 4 loops. Each one of the 4 SEND outputs has a microswitch able to run the earth connection. Other 2 microswitches run the connection of the audio earth and of the digital earth (dgt) to the metallic chassis. |
These particular switches managing the earth
connections, permit to solve the typical drawbacks of complex connections such
as buzzing and
noises which are mostly caused by the earth loops.
LS42 has, besides a socket for the external power supply, 7 poles MIDI connectors
for phantom power supply.
