SOUND ADVICE

The Consonance a120 Hybrid Integrated Amplifier is easy to connect and operate and
requires no prior technical knowledge. However, to get the most out of the amplifier's
superior sound and music quality, we have provided a brief description of the connections
and use of the amplifier in order to provide a total music experience.
We recommend keeping this user guide for future reference.

GENERAL USE

The amplifier is switched on with the button ①② Display. By pushing the same button one
more time the power is switched off.
When power is switched on, the blue display will light and keep flashing slightly. After
about 30 seconds, will stop flashing.
Note: It takes about 1 minute for the 6H30 tube to reach its normal operating point,
and only slight sonic improvement will be noticed after 5 minutes.
On the right of the front panel, the right knob ④ is the channel selector with selections:
INPUT1(" IN1"), INPUT2(" IN2"), INPUT3(" IN3"), BALANCED INPUT("BAL"), and the left
knob ③ is the volume control.
Avoid connecting input cables or selecting inputs with the source selector switch if the
volume setting of the amplifier is not fully turned down and the speakers are connected. A
transient signal might then arise, which can damage the speakers. The amplifier will not be
harmed, but to avoid overloading the speakers, the volume should be turned fully down or
the mute function should be switched on when connecting and disconnecting cables.
Note: The volume will be turned fully down automatically when the amplifier is
switched off and re-switched on for the same reason.
After the amplifier is switched on, there is a delay of about 30 seconds for the music signal
to reach the speaker outputs. The amplifier is protected against short-circuiting of the
speaker terminals , but we still recommend turning off the amplifier when connecting and
disconnecting signal and speaker cables.
The amplifier is designed to be used with a CD player, DVD player, cassette deck, tuner or
similar sound source.
