The Mackie DL32R represents a unique approach to digital mixing: a professional-grade mixing engine housed in a compact rack-mount form factor, controlled entirely through a tablet app. For churches with limited physical space or those wanting to position mixing control away from visible equipment, the DL32R offers elegant solutions. This guide walks you through initial setup and getting your audio flowing properly.
Understanding the DL32R Architecture
The DL32R is a digital mixer without a built-in control surface. All mixing happens through the Master Fader app on an iPad or Android tablet. This approach eliminates the need for large physical console furniture while providing complete mixing functionality. Your mixing operator controls everything from a tablet positioned anywhere with network connectivity to the mixer.
This architecture works beautifully for churches where aesthetics matter. You can hide the DL32R in a rack room while your operator controls mixing from a neat tablet interface. Alternatively, you can position the tablet prominently for backup operators to monitor while your primary operator works from a physical controller elsewhere.
Physical Installation and Networking
The DL32R is a 2-unit-high rack component, standard height for professional installations. Mount it in a standard audio rack with proper ventilation. Ensure the rear panel has adequate space for cable connections and airflow.
Connect the DL32R to your network via its Gigabit Ethernet port. Access the mixer’s System Settings through the Master Fader app and configure network parameters. The DL32R can obtain an IP address via DHCP or use a static address if your network infrastructure requires it.
For WiFi control, ensure your network extends to where you’ll position your tablet. Most churches use their existing facility WiFi, though some create a dedicated network for AV equipment to improve reliability.
Connecting Audio I/O
The DL32R provides 32 mic inputs (Onyx+ preamps) on its rear panel. Connect your wireless microphone receivers, instruments, and playback devices using the same gain-setting approach as other digital consoles.
Set each input’s gain by speaking into microphones or playing instruments, adjusting the input gain via the Master Fader app so peaks reach approximately -12 dB. Do this methodically for each input you plan to use, establishing consistent gain structure across all sources.
The DL32R provides analog outputs for your main stereo feed plus auxiliary buses. Connect your main stereo output to your PA amplifier or powered speakers. If you plan to use monitor mixing, connect auxiliary outputs to monitor amplifiers and speakers.
Configuring Your Main Mixing Bus
Open the Master Fader app on your iPad and connect it to the DL32R. Navigate to the Faders view, which displays all 32 channels as vertical faders. Select which channels you want feeding your main mix by pressing the corresponding channel’s MIX button.
Begin with your essential sources: lead vocal, backing vocal, acoustic guitar, keyboard, and backing track. Route these to your main mix. Don’t include ambient room microphones or overhead mics in the main mix yet—these serve monitoring or broadcast purposes.
Push the main mix fader up gradually while monitoring your output level on the main output meter within the Master Fader app. Aim for average levels around -18 dB with occasional peaks at -12 dB.
Initial Mixing Balance
Adjust the faders of individual channels to create your initial mixing balance. Start with the backing track at around -6 dB, then bring your lead vocal fader up until it sits prominently above the music. Add remaining instruments at levels that feel musically balanced relative to the lead vocal.
This initial balance doesn’t need to be perfect—it’s simply a starting point. You’ll refine it during rehearsal and make micro-adjustments during actual services.
Creating Scenes for Service Structure
The DL32R includes Scene memory, just like larger consoles. Save your current mixing state as a Scene that you can recall later. Create a “Sunday Baseline Setup” scene that represents your typical starting point.
For services with distinct segments, create additional scenes: “Worship Song Setup,” “Sermon Setup,” etc. During your actual service, recall the appropriate scene at each transition, instantly configuring the mixer for that portion of worship.
Setting Up Monitor Mixing
If your worship team benefits from stage monitors, configure the DL32R’s auxiliary buses for monitoring. Create a dedicated auxiliary output for your stage monitor feed. Assign sources to this auxiliary mix—perhaps kick drum, bass, and vocal for the band to hear themselves together.
Adjust levels in the monitor mix independently from your main mix. What sounds good for the congregation might not be ideal for musicians trying to lock together rhythmically. Provide custom monitoring that enables your band to perform confidently.
Network Connectivity and Tablet Placement
The Master Fader app on your iPad communicates with the DL32R over your network. Position your tablet where you can see the interface clearly and mix comfortably. Some churches mount the tablet on an arm at the back of the room, while others keep it portable so the operator can move to different locations.
If you’re using WiFi, monitor signal strength. If your tablet is too far from the WiFi router, you might experience lag or connection dropouts. Position closer to the router if problems occur, or consider adding a WiFi range extender to your facility.
Creating Custom Control Layouts
The Master Fader app allows you to customize what controls appear on your iPad screen. You might create a “Volunteer Basic” layout showing only essential controls, and an “Advanced Operator” layout with every available function.
Access the app’s layout settings and drag controls to customize the arrangement. This customization allows different operators to have appropriate complexity levels for their skill and responsibilities.
Backup Procedures
The DL32R stores your shows internally. Export them regularly to a USB drive or cloud storage. This backup protection ensures that if the mixer’s internal storage fails, you can restore your configuration quickly.
Keep multiple backup copies in different secure locations. Also keep a backup tablet with the Master Fader app installed, allowing a secondary operator to step in if your primary tablet encounters problems.
Commissioning Your Setup
Before trusting the DL32R with your first live service, spend substantial time in rehearsal becoming comfortable with the Master Fader interface. Practice creating scenes, adjusting levels, and managing mixing transitions.
Have your entire mixing team participate. Experienced volunteers should feel competent using Master Fader. New operators should receive training and practice time before expected to mix live services.
Your Mackie DL32R now provides sophisticated mixing control from a tablet interface. This flexibility enables churches to optimize their physical spaces while maintaining professional mixing capability at any location.
