9. Balanced stereo output connector. This connector has the following pinout : 1-ground, 2-left_hot,

3-left_cold, 4-right_hot, 5-right_cold. Mating connector : XLR5F.

For unbalanced operation pins 3 and 5 of the XLR 5 connector must be bridged to the ground pin

using bypass capacitors as pictured on the following diagram.

10. Left mic input connector. This connector has the following pinout : 1-ground, 2-hot signal, 3-cold

signal. Mating connector : XLR3M.

11. Right mic input connector. This connector has the following pinout : 1-ground, 2-hot signal, 3-

cold signal. Mating connector : XLR3M

AUTONOMY:

The autonomy of the AUDIOROOT FEMTO depends directly from the power source (battery type)

and microphones connected to the unit. Typical autonomy with 2 iPOWERUS 520mAh lithium-polymer

batteries and 2 SCHOEPS CMC64Ug microphones is 5 to 6 hours. This autonomy rises with dynamic

microphones, alcaline batteries or an external power source.

AUDIO INPUTS AND OUTPUTS:

The 2 "LEFT" and "RIGHT" XLR input connectors are disposed at the rear of the unit. These inputs

are electronically balanced with an input impedance of 5Kohms. Equipement with unbalanced outputs can

be connected to the FEMTO by bridging pins 1 and 3 and connecting them to ground. 48V phantom power

should be switched off when using unbalanced audio sources with the FEMTO

The preamp's stereo output is also disposed at the rear end of the FEMTO. This output is balanced

and is directly compatible with balanced inputs. The FEMTO can be connected to unbalanced inputs such

as those found on small handheld flash recorders by wiring the output as described in the diagram above

(cold pin outputs on the XLR 5 output connector must be bridged using bypass capacitors to enable

unblanced operation). Please contact us if you need to order custom cables for your FEMTO preamp unit.
