  • Page 2 Intended to alert the user to the presence of uninsulated Òdangerous voltageÓ within the productÕs enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. Intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.
  • Page 3: Front Panel Features

    2 has been designed to easily link multiple units together to form a single mixer with many more inputs (16, 24, 32...). The Automix 2 is supplied with a see-through plexiglass security panel to prevent changes to the installerÕs settings.
  • Page 4 INTERNAL PANEL INTERNAL PANEL FEATURES DIP SWITCHES Each channel has four DIP switches that control the following functions. MAN/AUTO This switch determines whether the channel is operating in the automatic or manual mode. OFF/MBUS This switch is used to connect the channel to the system mutebus. This allows multiple inputs to be muted simultaneously under external control.
  • Page 5 PRIORITY (CHANNEL 1 and 2 ONLY) Turning the priority control clockwise allows one channel to override the others in the mix. It does this by ÒtrickingÓ the gain computing circuits into thinking this channel is louder than the others. Up to 9dB of priority is available. AUX MASTER LEVEL CONTROL This control sets the level of the signal being sent to the Aux Out.
  • Page 6: Back Panel Features

    BACK PANEL FEATURES MIC INPUTS For use with low impedance microphones or low level sources. This is a transformer balanced input with an impedance of 2,000½. Input sensitivity for nominal output is -56dBu to -19dBu. LINE INPUTS These allow line level inputs to be used. This is a transformer balanced input through a 30dB resistive pad.
  • Page 7: Status Output

    MUTE Channels can be muted individually by shorting this terminal to ground. It provides approximately 45dB of attenuation. STATUS OUTPUT The status output is a DC logic output that is high (+5 Volts) when the channel is active and low (0Volts) when the channel is not active. This DC voltage can be used to key video cameras or trigger key lights on active microphones.
  • Page 8: Link Switch

    Select the mixer to be used as the master and place its link switch in the ÒmasterÓ position. All other mixers in the system should have their link switches in the ÒslaveÓ position. You now have a 16 (or more) channel automatic mixer. The master controls of the unit chosen as ÒmasterÓ...

  • Page 12 Setting the Overall Level: Set the master level control (external) for the desired overall output level. This mixerÕs levels are now set and the mixerÕs other features (downward expander, low cut and priorities) can be set as desired for the application. Attaching the Security Panel: Attach the security plexiglass with the eight supplied screws.
  • Page 13 (16, 24, 32É). Para evitar modificaciones a las configuraciones del instalador, el mezclador Automix 2 se suministra con un panel de seguridad de plexiglas transparente. Consulte los diagramas del panel delantero en la secci—n de inglŽs de est manual.
  • Page 14 permite que varias entradas se silencien simult‡neamente mediante un control externo. Vea BUS DE SILENCIADO en la p‡gina 7. CORTE DE BAJOS/PLANO Este conmutador selecciona el filtro de corte de bajos. El filtro de corte de bajos provee atenuaci—n progresiva de baja frecuencia, que ayuda a minimizar los ruidos no deseados (movimiento de micr—fonos, golpes en la mesa, etc.).

Gire lentamente el expansor descendente hacia la derecha, hasta que se atenœe el ruido ambiente de fondo entre las palabras. Tenga cuidado de no excederse. Cuanto m‡s expansor descendente se utilice, menos "natural"...
  • Page 16 ENTRADAS DE LêNEA Permiten utilizar entradas con nivel de l’nea. Son entradas equilibradas por transformador a travŽs de un atenuador resistivo de 30 dB. La impedancia de entrada es >20 k½. ENTRADA/SALIDA DE INSERCIîN Es un circuito de se–al que permite insertar un dispositivo externo, tal como un ecualizador, en el camino de la se–al de los canales individuales (consulte el diagrama m‡s abajo).
  • Page 17 ESTADO DE SALIDA El estado de la salida es una salida l—gica de CC que est‡ en condici—n alta (+5 V) cuando el canal est‡ activo, y baja (0 V) cuando est‡ inactivo. El voltaje de CC se puede utilizar para excitar videoc‡maras o disparar luces indicadoras en micr—fonos activos.

  • Page 19 INTRODUCTION Nous vous fŽlicitons pour lÕachat de cet Automix mixeur automatique haute qualitŽ possŽdant huit entrŽes micro/ligne symŽtriques (transformateur). Chaque canal poss•de un contr™le de gain, une alimentation phantom 48 Volt (entrŽes micro), une filtre coupe-bas, une LED dÕactivitŽ/Žcr•tage, un contr™le Aux send et le choix entre une opŽration manuelle ou automatique.
  • Page 20 LO CUT/FLAT Ce sŽlecteur actionne le filtre coupe-bas. Ce filtre attŽnue les frŽquences graves afin de minimiser les bruits indŽsirables (manipulation du micro, etc...). La frŽquence de coupure est fixŽe ˆ 100 Hz (-3dB) et la pente du filtre est de 6dB par octave.
