  • Page 4 The 442 incorporates a complete feature-set into a compact, functional design. With no hidden controls, the 442's parameters are accessible from the three main surfaces. The highly effi cient circuitry allows the mixer to be powered by either four internal AA batteries or external 5-18 VDC.

  • Page 5: Quick Start Guide

    For internal powering, insert four AA batteries with the positive (+) side fi rst into the battery compartment. For external powering, connect the external DC power (5–18 VDC) to the 442's DC connector. Slide the power switch in the direction of the intended power source (INT or EXT).

    With the Channel Fader set to unity gain (0 dB or 12 o’clock), make the appropriate adjustments with the Gain (trim) pot. Make coarse gain adjustments with the Gain (trim) pot during setup. Once the gain is set to the desired level, recess the Gain (trim) pot to hide it from the 442’s mixing surface.

  • Page 11: High-Pass Filters

    Dynamic microphones will operate as normal when phantom power is applied to them. The 442 can provide up to 10 mA to each input at 48 V, suffi cient for the most power-hungry condenser microphones. Many phantom powered microphones do not require 48 V and can be properly powered with 12 V.

  • Page 12: Pan Controls

    The Pan potentiometer controls the respective input's stereo image that is sent to the Stereo Output bus. The 442 uses constant loudness pan controls, meaning that the signal is 3 dB louder at the full-right or full-left positions relative to the center position. For most applications, the channel will be panned either hard-left, hard-right, or center;...

    PFL metering can be deactivated in the Setup Menu. Outputs The 442 is a two-bus mixer with several outputs, this is essential for multi-camera, multi-source productions. Because each input can be continuously panned from left to right, the mixer can be used with either two mono buses or with a single stereo bus.

  • Page 14: Secondary Balanced Outputs

    See Setup Menu At Factory Default, the mixer is set to limit the output signal peak levels to +20 dBu. This assures that the output of the 442 will not overload inputs that accept full line-level signals (+24 dBu peak).

  • Page 15: Link Vs On

    To Link two 442s together: Connect the TAPE OUT/MIX OUT of 442 A to the MIX IN of 442 B with a TA3F to TA3F cable (Sound Devices XL-1B optional accessory). This will send the stereo mix of 442 A directly to the stereo output bus of 442 B.

  • Page 16: Metering

    In VU mode, the front panel meter labeling is in volume units. VU meters are always referenced to an actual signal level in dBu, the 442 VU meter is referenced with 0 VU corresponding to 0 dBu at the Line- Level outputs.

  • Page 17: Headphone Peak Led

    Headphone gain is controlled by a pop up knob to remove it from the mixing surface. The 442 can drive headphones to dangerously high volumes. Turn down the headphone gain control before selecting a headphone source to prevent accidental signal extremes.

  • Page 18: Powering

    External Powering The 442 can be powered from any DC voltage from 5 to 18 VDC. Pin-4 of the locking, Hirose connector is positive (+) and pin-1 is negative (–). The external DC supply is completely isolated (fl oating) from the rest of the mixer for easy and safe interconnection to other external audio gear.

  • Page 19: Tone Oscillator / Slate Microphone

    A single 3-position switch controls both the tone oscillator and the slate microphone. Tone Oscillator Tone is used to set gain structure between the 442 and the next device in the signal path. The tone oscillator uses the locking position of the switch.
