Thank you for purchasing the UNiKA PRO SERIES AUDIO INTERFACE. Before using,
please read this manual carefully and pay attention to every detail that you must pay
attention to. If you use a mixer to connect to this interface, please turn off the mixer
power and +48V phantom power before connecting, and then turn on the power and
phantom power after inserting the signal cables. For passive models, please do not
turn on the phantom power to avoid leakage or damage the equipment.
If using a model with a volume knob, turn the volume knob to the minimum. During
use, please do not plug or unplug the wires arbitrarily to avoid signal loss. Please
refer to the following instructions for the soldering method of the plugs to ensure the
expected level and keep the signal smooth.

PRODUCT OVERVIEW

PRO 148 is an active single-channel DI box. Unlike traditional DI, PRO 148 uses +48V
phantom power instead of the traditional 9V dry cell battery, so users can use it on the
mixer or external phantom power supply. Power is supplied to PRO 148, the power
supply circuit and the output signal line are shared, and no additional power cord is
required. The +48V indicator is set on the upper cover. The +48V circuit specially
selects the British OEP PT-4 pulse transformer.
TM
EI30A10E 1+1:1+1 isolation transformer, which
PRO 148 has a built-in UNiKA-PRO
has a special copper foil layer and a dedicated ground layer, which allows this device
to restore high signal/noise ratio and dynamic sound, and can avoid unnecessary
leakage caused by radio frequency interference, ground interference and potential
difference. PRO 148 is especially suitable for electronic musical instruments, recording
studios and fixed installation projects by using mixers.
The PRO 148 uses a balanced/unbalanced combo socket on the input, and a TRS
through out is convenient for musician to pass the direct signal to the instrument
amplifier. In addition, it is equipped with a 0/-20dB attenuation switch and LED
indicator, which is suitable for various types of audio signals with high and low
impedance. The output terminal is also equipped with a GND/LIFT button to quickly
eliminate ground noise.
