Fully Balanced
Dual Monaural Headphone Amplifier
The UD-507 is a headphone amplifier featuring the TEAC-HCLD2 high current line driver,
which is characterized by its high current supply capability.
Compared to the previous model, the maximum output power has been greatly
improved by strengthening the power supply, resulting in a generous driving power of
1,200mW + 1,200mW (balanced output at 100 ohm load),
which is comparable to a dedicated headphone amplifier without DAC.
The power amplifier gain can be switched between 3 positions (Low/Mid/High)
to fine-tune the output to best match the sensitivity and impedance of the headphones.
High-Quality Preamplifier
with Multiple Analog/Digital Inputs
The UD-507 incorporates the TEAC-QVCS high precision analog volume attenuator
and the powerful TEAC-HCLD2 high current line buffer circuit.
With five digital inputs and two analog inputs (unbalanced and balanced),
a wide variety of devices can be connected.
