  • Notes

  • A hi-fi multi-mixing amplifier with 6 inputs, parametric equalization and electronic echo.

    Features
    • 6 inputs for mixing:
    The MA-100 accepts and mixes one tape, one source and four additional inputs, a total of six inputs. The last four may be any combination of electric instruments (guitars, etc.) and microphones.

    • Panpots for the additional inputs (CH. 1 through 4):
    The sonic image can be moved and fixed anywhere within the stereo sound field.

    • Echo, chorus and duet:
    To each of the six individual inputs, the MA-100 can apply one special effect in addition to echo. Chorus adds a backup group to a solo act; duet turns a solo into a duet.

    • BBD (Bucket Brigade Device) electronic echo:
    For natural, low-distortion application of echo. Adjustable over a 3-second range.

    • Parametric equalizer for two inputs (CH. 3 and 4):
    Select two frequencies, any low frequency between 100Hz and 900Hz, and any high frequency between 1kHz and 13kHz. Gain for each selected frequency is variable over a ±10dB range.
