2. Caratteristiche principali

The Mackie SR24.4 VLZ Pro mixer is designed for professional audio applications, offering robust performance and a comprehensive feature set:

  • XDR Microphone Preamps: Equipped with high-quality XDR (Extended Dynamic Range) microphone preamps for excellent signal integrity and low noise.
  • VLZ Circuitry: Features VLZ (Very Low Impedance) circuitry, contributing to the mixer's high headroom and low noise floor.
  • 24 canali: Provides 24 input channels, suitable for a wide range of live sound and studio recording scenarios.
  • High Headroom Design: Main and submix amplifiers utilize Mackie's negative gain mix architecture, offering double the mix headroom compared to conventional designs.
  • Costruzione robusta: Built for durability and reliability in demanding environments.

3. Guida all'installazione

Proper setup is crucial for optimal performance. Follow these steps to connect your mixer:

  1. Disimballaggio e posizionamento: Estrarre con cautela il mixer dalla confezione. Posizionarlo su una superficie stabile e piana, assicurando un'adeguata ventilazione attorno all'unità. Evitare di posizionarlo vicino a fonti di calore o alla luce diretta del sole.
  2. Collegamento elettrico: Ensure the mixer's power switch is in the OFF position. Connect the supplied AC power cord to the mixer's power inlet and then to a grounded AC power outlet.
  3. Connessioni di ingresso:
    • Connect microphones to the XLR inputs (MIC IN) on each channel using balanced XLR cables.
    • Connect line-level sources (e.g., keyboards, drum machines) to the 1/4-inch TRS/TS LINE IN jacks.
    • For stereo sources, use two adjacent channels or dedicated stereo input channels if available.
  4. Connessioni di uscita:
    • Connect the MAIN OUT (XLR or 1/4-inch) to your power amplificatore o altoparlanti amplificati.
    • Connect AUX SEND outputs to external effects processors or monitor amplificatori.
    • Connect CONTROL ROOM OUT to studio monitors for critical listening.
    • Collegare le cuffie alla presa PHONES.
  5. Accensione iniziale: Before powering on, ensure all channel faders are down, and the main mix fader is at its lowest setting. Power on any connected devices (amplifiers, powered speakers) last. Then, switch on the mixer.

4. Istruzioni per l'uso

This section outlines the basic operation of the Mackie SR24.4 VLZ Pro mixer.

4.1 Channel Strip Overview

Each input channel features controls for gain, equalization, auxiliary sends, pan, mute, solo, and level fader.

  • Manopola GAIN: Adjusts the input sensitivity for the microphone or line input. Set this to achieve a healthy signal level without clipping (indicated by the PEAK LED).
  • Sezione EQ: Typically includes High, Mid (with sweepable frequency), and Low frequency controls to shape the tone of the input signal.
  • AUX SEND Knobs: Control the amount of signal sent from the channel to the auxiliary outputs, used for monitors or effects.
  • Manopola PAN: Posiziona il segnale del canale all'interno del campo stereo (da sinistra a destra).
  • Tasto muto: Silences the channel's output to the main mix and subgroups.
  • Pulsante SOLO: Isolates the channel's signal for monitoring through headphones or control room outputs without affecting the main mix.
  • Fader di canale: Adjusts the overall level of the channel's signal sent to the main mix and subgroups.

4.2 Main Mix and Subgroups

The main mix combines all active channels into a stereo output. Subgroups allow for routing multiple channels to a single fader for easier control.

  • Fader MIX PRINCIPALE: Controlla il livello di uscita complessivo del mix stereo principale.
  • SUBGROUP Faders: Control the output level of grouped channels. Channels are assigned to subgroups using routing buttons on each channel strip.
  • METRI: Provide visual feedback of signal levels for the main mix and subgroups. Aim for levels that are strong but do not consistently peak into the red.

4.3 Monitoraggio

Use the Control Room and Headphone outputs for monitoring your mix.

  • CONTROL ROOM Level: Adjusts the volume for your studio monitors.
  • Livello TELEFONI: Adjusts the volume for headphones. Note that on some models, this may share a control with the Control Room output.

5. Manutenzione

Regular maintenance ensures the longevity and reliable operation of your mixer.

  • Pulizia: Disconnect power before cleaning. Use a soft, dry, lint-free cloth to wipe down the exterior. For stubborn dirt, a slightly damp È possibile utilizzare un panno imbevuto di sapone neutro, seguito da un panno asciutto. Evitare detergenti abrasivi o solventi.
  • Protezione dalla polvere: Keep the mixer covered when not in use to prevent dust accumulation, which can affect faders and potentiometers.
  • Condizioni ambientali: Operate and store the mixer in a cool, dry environment, away from extreme temperatures, humidity, and direct sunlight.
  • Gestione dei cavi: Ensure cables are neatly organized and not under strain to prevent damage to connectors and inputs/outputs.

  • Mute button engaged on channels or main mix.
  • Cavi collegati in modo errato o difettosi.
  • Amplifier/powered speakers off or muted.
  • Controllare i collegamenti elettrici e l'interruttore.
  • Alzare i fader ai livelli appropriati.
  • Disattivare i pulsanti di disattivazione audio.
  • Verify all cable connections and test cables.
  • Controllo amppotenza e volume dell'amplificatore/altoparlante.
Ronzio o rumore di ronzio
  • Anello di terra.
  • Unbalanced cables used for long runs.
  • Interferenze da altri dispositivi elettronici.
  • Ensure all equipment is on the same electrical circuit or use a ground lift (with caution).
  • Use balanced cables (XLR or TRS) where possible.
  • Move mixer away from power supplies, computers, or fluorescent lights.
Suono distorto
  • Guadagno di ingresso troppo alto.
  • Livello di uscita troppo alto.
  • Cavo o componente difettoso.
  • Reduce input GAIN until PEAK LED no longer illuminates.
  • Lower main mix or channel faders.
  • Test with different cables and isolate the faulty component.
