B-16 Buffered Audio Loop & Switch

MARK L Custom Guitar Midi Loop B-16:

perfectly transparent sound
all loop RETURN buffered ( BURR BROWN OPA Line Driver )
ultra-clean sound
signal to noise ration comparable to CD quality recordings (102dB)
no dynamic loss
full bandwidth
silent, click-free switching, even in high gain level
MIDI compatibility
six relay contact closures (S1-S6) for devices utilizing switch to ground functions
high grade low noise line driver ( BURR BROWN OPA Line Driver )
alternating or direct current operation

B-16 is equipped with 10 buffered audio loops, 6 switches ground separated.
B-16 is controlled by MIDI CC (Control Change) commands over 16 MIDI channels.
B-16 is compatible with any type of MIDI controller capable of sending CC commands, but to ensure proper operation and maximum effectiveness we recommend using MARK L controllers.

Buffered signal ensures same impedance level on every loop, ensuring that there is no mismatch in the sound of your pedals.The difference is as if every effect was a self-standing-unit, without any tone-dependence of one by another.

The effects loop can be hooked up with:

10 mono effects (10 effects plugged in before the amplifier)
10 mono effects (10 effects plugged in the amplifier’s FX LOOP )

By dividing the loop into two sections we can plug in:

10 mono effects (6 before the amplifier and 4 in the amplifier’s FX LOOP)

FRONT PANEL:
The front panel consists of 17 LED diodes informing which loop (L1-L10) or which switch (S1-S6) is on and a MIDI light which informs if the device is receiving MIDI signals.

To connect to the FC-25 use the lockable XLR6. MIDI-IN is equipped with additional power supply thanks to which the FC-25 may be powered by the LS-16 ( pin 1-2 AC power for FC-25, pin 4-5 MIDI DATA, pin 3-6 12AC power for FC25 DC converter). To connect audio through a high impedance line buffer, connect to the lockable JACK 6,3MM GUITAR IN

REAR PANEL:
The rear panel consists of 6,3 mm ‘jack’ inputs used for connecting effects, audio signals and control switches for the amplifier and other devices
