    The TOA M-243 is a highly flexible rack mount mixer with
    two monaural and four stereo inputs, plus one stereo and
    two mono outputs. There are also mix bus .sub-inputs. and
    a stereo record output. It is designed especially for
    commercial systems that require mixing and matrixing a
    combination of mono and stereo audio sources to one or
    several outputs, and in which stereo sources may have to
    be summed to mono and monaural sources sent to L/R
    The compact, single rack space M-243 can be easily
    configured to serve as anything from a single mono or
    stereo mixer to a mixer with six regular inputs and three
    outputs. Each output also has its own separate sub-input.
    The M-243 is ideal for a variety of systems, including
    boardrooms, conference rooms, health clubs, restaurants
    and background music (BGM) applications. For example,
    in a restaurant, the M-243 can simultaneously and
    separately control stereo classical music in the dining room,
    stereo easy listening music in the bar and foyer, plus BGM
    and paging of customers when their tables are ready.
    The M-243 has two monaural line inputs (#1 and 2) that are
    switchable between balanced XLR microphone level or
    unbalanced 1/4" phone line level, and four unbalanced L/R
    stereo inputs (#3~6) with RCA-type jacks. Input 6 has both
    RCA type and 1/4" phone jacks connected in parallel. Each
    of the inputs has its own volume control and a set of three
    assignment switches for assigning the input to any
    combination of the three outputs. The two monaural inputs
    each have an automatic compressor to prevent excessive
    input signals from clipping the mixer output. Each also has
    a high pass filter to filter out unwanted low frequencies,
    particularly for speech use, and a -20dB pad in the mic
    input circuitry to accommodate high output or close-talked
    microphones. Filter and pad on/off switches are internal to
    prevent any tampering.
    The M-243 has other line level inputs: a L/R stereo sub-input
    and mono sub-inputs 1 and 2. These directly feed the
    mixing buses and their associated outputs. The stereo
    sub-input is configured so that by connecting a monaural
    signal to the left channel, it will be fed to both the left and
    right output channels. Among other applications, one of the
    monaural outputs could be fed into the stereo sub-input as
    a sub-group mix for the stereo output.
    A unique feature of the M-243 is an automatic muting
    function (switchable on/off). This detects signal on either of
    the monaural inputs and mutes any of the stereo input
    signals assigned to the L/R stereo output. This is very
    useful for priority paging that auto-mutes BGM or for
    automatic program selection. For example, in a sports
    lounge, the TV audio could automatically mute the BGM
    whenever the TV is turned on. Meanwhile, because the
    stereo input assignments to the mono outputs are
    unaffected, the same BGM signal could still go
    uninterrupted to the associated restaurant system that is
    being fed from one of the mono outputs.
    Three sets of output mixing buses are provided to feed the
    three sets of main outputs: L/R Stereo, Mono 1 and Mono 2.
    Each output has a separate volume control on the front
    panel. The L/R Stereo output also has bass and treble
    shelving-type tone controls. Each of the mono outputs has
    an internal switch that allows it to function as a sum of the
    stereo output. There is also a L/R stereo recording output
    from the L/R stereo mix bus prior to the output EQ and
    Other features include provision of colored control knobs for
    the different control functions; a clipping indicator that lights
    when any signal in the output section reaches 3dB below
    clipping; an internal ground lift switch that separates the
    audio and chassis grounds to avoid ground loops; an
    included security cover for the assignment switches and a
    power switch with a power-on indicator. The M-243
    occupies only one standard 19" EIA rack and includes
    removable rack mounting ears.
