Features

  • Up to 200 watts per channel into 4 and 8 ohms — the outputs of the SPA4-100 model are designed to provide up to 100 watts per channel into Low-Z loads.
  • ENERGY STAR® qualified amplifier - The ENERGY STAR qualified SPA amplifiers employ an efficient class-D design to conserve energy and reduce operational cost.
  • Bridgeable outputs for higher power — Bridgeable outputs for higher power - Bridging the outputs of the SPA4-100 will deliver up to 350 watts into 70V or 100V when bridged.
  • Auto-Ramp provides quiet startup and power-down — The ENERGY STAR auto-ramp circuitry ensures quiet and fast power up from standby and seamless power-down following 25 minutes of inactivity, dramatically reducing power consumption.
  • Rack-mountable 1U, half rack width enclosure — The SPA amplifers can be mounted in 1 RU, 1/2 rack space, and their clever joining brackets enable easy under-table and wall-mounting

    Description

    1/2 RU 4 Channel ENERGY STAR amplifier / Multichannel Operation 100 watts into 8Ω & 4Ω, Bridged pair operation 200 watts into 8Ω & 4Ω, and 350 watts into 70v and 100v / 100-240 VAC Operation


    The SPA4-100 four channel amplifier delivers 100 watts rms per channel into 4 or 8 ohms; the four channels can also be bridged in pairs, each pair providing up to 200 watts rms into 4 or 8 ohms. The SPA4-100 bridged pair channels can be switched into 70V or 100V direct drive mode providing up to 350 watts rms into a 70V or 100V output; when in 70V or 100V mode the 80Hz highpass filter is automatically engaged.

    Specifications

    SPA Series

    Features

    • Up to 200 watts per channel

    into 4 and 8 ohms - the outputs

    of the SPA2 and SPA4 -60 models

    are designed to provide up to 60

    watts per channel while the SPA4-

    100 will provide up to 100 watts

    and the SPA2-200 will provide

    up to 200 watts per channel into

    Low-Z loads

    • ENERGY STAR qualified

    amplifier - The ENERGY STAR

    qualified SPA Series employ an

    efficient class-D design to conserve

    energy and reduce operational cost

    • Bridgeable outputs for higher

    power - Bridging the outputs of

    the SPA -60 amplifiers provide up

    to 250 watts, while the SPA2-200

    and the SPA4-100 will deliver up to

    175 watts into 70V or 100V when

    bridged

    •Auto-Ramp provides quiet

    startup and power-down - The

    ENERGY STAR auto-ramp circuitry

    ensures quiet and fast power

    up from standby and seamless

    power-down following 25 minutes

    of inactivity, dramatically reducing

    power consumption

    •Rack-mountable 1U, half rack

    width enclosure - The SPA Series

    can be mounted in 1 RU, 1/2 rack

    space, and their clever joining

    brackets enable easy under-table

    and wall-mounting

    The SPA Series amplifiers from QSC are

    four, half-rack RU, convection cooled power

    amplifiers delivering two or four channels of up

    to 200 watts per channel into 4 Ω and

    8 Ω. These amps can also be bridged to

    supply up to 400 watts into 4 Ω and 8 Ω,

    and up to 350 watts into 70 V or 100 V loads

    making them extremely flexible for Low-Z or

    High-Z applications. Utilizing an advanced

    Class-D amplifier design and Universal

    Power Supply, the SPA Series are efficient,

    allowing them to be convection cooled and are

    ENERGY STAR qualified with quiet auto-ramp

    standby functionality. The SPA Series

    are housed in an unobtrusive black painted

    1/2 RU chassis with unique mounting

    hardware enabling rack, table and wall

    mounting capabilities.

    Efficient Amplifier with Auto-Ramp

    The SPA Series amplifiers utilize a highly

    efficient class-D design that conserves

    energy to reduce operational costs and

    requires no active cooling. They are ENERGY

    STAR qualified with auto-ramp circuitry that

    seamlessly transitions to/from Standby with

    no audible pops.

    Amplifier Protection

    All amplifiers in the SPA Series feature rms and

    thermal limiting, as well as protection against

    over current, short circuit, and under/over

    voltage.

    Protection, Control and Mounting

    The SPA Series provide rms and thermal

    limiting as well as over-current and shortcircuit protection so you can employ them

    with confidence. They also come with multiple

    mounting options. Every SPA Series comes

    with a complete mounting kit allowing it to

    be rack mounted by itself or with a second

    unit in a 1RU space. Included connecting

    brackets provide additional strength when

    rack mounting two amps together, but also

    make for simple under-table or wall mounting

    (like behind a TV). The SPA Series can also be

    mounted in plenum spaces when used with

    the Plenum Kit accessory.
