Power amplifier

The true ability can authentically drive speakers - real Masterwork of amplifier - the RE - the starting point of PHASS

    Two types amplifier circuits are available in RE series,


    *RE 2, RE 2.2, RE 50, RE 50 HI and RE 100M - “Standard Push pull” amplifier


    *RE 2.65 and RE 4.25 - “Single End Push Pull” amplifier

  • Balance input type

    RE 2

    • maximum power output:40W x 2(1 KHz / 10 ohm,RMS)
    • input sensitivityinput impedance10 K ohm):
    • RCA / -10 dBV(0.3 V)
    • Balance/ -18 dBV(0.13 V)
    • Max input level:
    • RCA / +18 dBV(8 V)
    • Balance/ +10 dBV(3.2 V)
    RE 2 Balance input  by BLD ( Balance Line Driver )

    RE 2 - 2 channel amplifier ( Balance / RCA input )

    The RE 2 amplifier, which has easily surpassed sound quality of home audio amplifiers, is now equipped with a balanced line input stage, resulting in further improved sound quality.
    When the signal form the source unit is transmitted to the RE 2, it is converted to a balanced signal by a BLD (Balanced line driver) at the input of the RE 2. This pure signal is then transmitted by the constant current driving of RE 2 to the connected speakers.
    The balanced line input stage of RE 2 takes music reproduction to a higher place.

    Max output power:40Wx2 (RMS, 1KHz,10ohm) / Input sensitivity(10 K ohm): RCA -10dBV(0.3V), Balance -18dBV(0.13V) / Max input level: RCA +8dBV(8V), Balance +10dBV(3.2V) / Load impedance: 4-16ohm / Consumption current: Idling time (no signal) 3A, Remote off time: 2mA / Size(mm): 320(W)x92(H)x504(D)

    RE 2.65

    RE 2.65 and BLD balance line drive configuration

    RE 2.65 - 2 channel amplifier ( Balance / RCA input )

    We set out to create a SEPP amplifier that would be a part of our RE Series and offer such excellent sound quality that it would not bring dishonor to the Phass RE name and reputation. We accomplished our objective and proudly offer the RE 2.65 as the secondary SEPP based RE Series amplifier. NON-NFB circuit produces appropriate output power suitable for delivering electric current to speakers with quite low noise, allowing the amplifier to easily control speakers and produce vivid sound. Our sound design concept places RE 2.65 on the extremity of SEPP amplifiers.

    Max output power:65Wx2 (RMS, 1KHz, 8ohm) / Input sensitivity(10 K ohm): RCA 1.6V / Consumption current: Idle time (no signal) 1A, Remote off time: 2mA / Size(mm): 250(W)x56(H)x326(D)

    RE 50HI

    Basic configuration of RE 50HI

    RE 50HI / 2ch amplifier ( Speaker signal input )

    RE 50HI is a power amplifier which has a high input (speaker signal input) stage without a RCA signal input stage. It can transmit the music signal which was outputted from another power amplifier to the connected speakers simply as the constant current driving amplifier. The speaker signal means that it is the balance transmission signal, and its signal can be transmitted to RE 50HI without getting any disturbances and noises. Accordingly RE 50HI which can be inputted such clean balance signal can perform great and coherent sound impressively.

    Output power: 2x50W  / Input sensitivity : 5V  / Load impedance : 4-16 ohm /  Consumption current : Idling time (no signal) - 3A, Remote off time : 2mA  / Size (mm) :280(W)x74(H)x320(D)
