    Description

    1/2 RU 2 Channel ENERGY STAR amplifier / Stereo operation 60 watts into 8Ω & 4Ω, Bridged operation 200 watts into 8Ω & 4Ω, and 250 watts into 70v and 100v / 100-240 VAC Operation



    The SPA Series amplifiers from QSC are two half rack 1U, convection cooled power amplifiers delivering two or four channels of 60 watts per channel into 4Ω and 8Ω. These amps can also be bridged to supply 200 watts into 4Ω and 8Ω, and up to 250 watts into 70V or 100V 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 amazingly efficient allowing them to be convection cooled and are ENERGY STAR® qualified with quiet auto-ramp standby functionality. The SPA2-60 and SPA4-60 are housed in an unobtrusive black painted 1/2 RU chassis with unique mounting hardware enabling rack, table and wall mounting capabilities.

    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.
