General Information
Ear-909 is an uncompromising headphone amplifier. It uses the same type of output stage 90 ear, but it has a completely different power supply systems and a finer volume control.
Nätdelssytemet in Ear 909 comprises a main controller which is complemented with its own controller per channel. This means that the highly sensitive amplifier stages are guaranteed a perfect power supply that is both low noise and free from interference.
Volymkomtrollen in Ear 909 uses a mechanical switch for each volume mode, connect a voltage divider consisting of two resistors. Better than that is not a volume control.
Ear-909 has two types of outputs: One is the headphone so standard 6.3 mm connector and an output differential. The differential output has contacts with four poles and three poles.
For the four-pole connector is a cable with two twisted pairs of wires inside. It is advantageous if the pairs are shielded from each other.
For the two-pole connectors to connect a cable per channel. It is usually the easiest.
