The Allen & Heath SQ-5 stands as one of the most versatile and intuitive digital mixers available for mid-to-large churches. With its 48-channel capacity, comprehensive routing capabilities, and industry-leading build quality, the SQ-5 can grow with your ministry’s audio needs. Getting the console up and running properly from day one is essential to avoid technical difficulties during crucial Sunday services and special events.
Understanding the SQ-5 Architecture
Before connecting anything, it helps to understand how the SQ-5 organizes its audio. The console provides a physical input count that can be expanded through digital networking via dSNAKE or GigACE. Think of the SQ-5 as a control center rather than just an analog mixing board. The actual mixing engine is separate from the physical hardware, which means you can configure signal flow in ways that wouldn’t be possible on traditional analog consoles.
The main mixing engine includes 24 physical analog inputs on the mixer itself, plus additional channels available through digital connections. You’ll also have access to 8 subgroup outputs, stereo main output, and numerous auxiliary buses for monitors, effects, or broadcast feeds. Understanding this modular approach helps explain why the SQ-5 is so flexible for churches handling everything from Sunday worship to conferences and special services.
Initial Power-On and Network Setup
Start by ensuring all cables are disconnected except for a standard two-prong power cable. The SQ-5 requires stable AC power, so connect it to a quality power conditioner if possible. Press the power button and allow the mixer to boot for about 60 seconds. You’ll see the Allen & Heath logo appear on the touchscreen, followed by the main mixing interface.
For churches planning to use iPad control or dSNAKE stage boxes, network setup happens early in the configuration process. Navigate to the Setup menu by touching the screen and finding the System Settings option. You’ll need to configure the Ethernet ports for your specific network topology. The SQ-5 includes both Gigabit and standard Ethernet ports, giving you flexibility in how you connect to your existing church network infrastructure.
If you’re not using digital networking initially, you can skip this step and rely solely on the analog inputs for now. Many churches start simple and add digital connectivity later as their technical expertise grows.
Connecting Your Primary Inputs
The physical analog inputs on the SQ-5 connect via three-pin XLR and quarter-inch phone jacks, depending on your cable types. Start with your most critical audio sources: wireless microphones, line-level instruments, and your altar/congregational area microphones. Each input has a clearly labeled channel on the mixer.
Connect your wireless mic receivers first. The SQ-5 accommodates both balanced and unbalanced inputs, though XLR balanced connections are preferred for RF-noisy church environments. Route these to channels one through four initially, leaving some organization so you can remember which channel handles which wireless system. Turn the channel faders completely down before connecting any inputs to prevent sudden audio bursts that could startle your congregation.
Once your inputs are physically connected, you’ll adjust input gain on the mixer itself. Unlike older analog consoles, the SQ-5 has rotary encoders and a colorful screen that shows real-time input metering. Touch each channel on the screen and look for the input gain parameter. Bring your source signal (speak into the microphone) and adjust the encoder until the peak level shows around -12 dB on the digital meter, giving you healthy headroom without distortion.
Configuring Your Main Output
The heart of any church audio system is the main stereo output. The SQ-5 has a dedicated stereo main output, but you need to route your mixed audio to it. Touch the Outputs section of the mixer interface and find the MAIN output. This is where your final mixed audio emerges before heading to your powered speakers or amplifier.
Create a simple flow: your microphones and instruments feed into channels, then you need to assign these channels to a master fader. The SQ-5 uses what Allen & Heath calls the “Mix Rack,” which you’ll see as a section on the right side of the touchscreen. Touch the MIX1 fader to make it your primary mixing destination, then assign your input channels to it by pressing the corresponding channel’s MIX1 button.
Once your channels are feeding the main mix, push the MIX1 fader up slowly while monitoring your output. Many churches use a simple handheld SPL meter or their ears to check that the levels are appropriate. You want the average speech to sit around -18 dB on the output meter, with occasional peaks reaching -12 dB for singing or announcements.
Basic Channel Organization and Scene Memory
Before you move into advanced routing, establish a naming convention for your channels. The SQ-5 makes this easy through the touchscreen interface. Double-tap a channel’s name to edit it. Create clear labels like “Wireless 1: Lead Vocal,” “Wireless 2: Keys,” “Wireless 3: Worship Leader,” and “Stage Mic.” This simple step saves enormous amounts of confusion when volunteers operate the mixer or during transitions between different services.
With your basic inputs routed to your mains output, save your current setup as a Scene. The Scene memory system in the SQ-5 is remarkably powerful. Navigate to the Show section, then press “New Scene” and name it something like “Sunday Baseline Setup.” This preserves all your current fader positions, routing assignments, and processing settings. If a volunteer accidentally changes something, you can instantly recall this baseline scene and get back to a working state within seconds.
Adding dSNAKE Digital Networking (Optional Initial Setup)
If your church plans to place microphones on stage or in separate rooms, dSNAKE stage boxes extend your input count wirelessly. The SQ-5 supports both dSNAKE and GigACE networking protocols. Start with a single dSNAKE box placed near your stage microphone locations. Run a single Ethernet cable from the SQ-5 to the stage box, which can be up to 300 feet away depending on your cable quality.
Power the dSNAKE box from a standard wall outlet and wait for the connection light to illuminate on both the box and the mixer. Navigate to the System Settings and verify that the SQ-5 recognizes the connected stage box. When properly connected, the physical inputs on the stage box appear as channels within the SQ-5’s mixing interface, just as if they were directly connected to the main console.
Finalizing Your Baseline Setup
With your primary inputs connected and mains working, take time to establish good habits for your volunteer team. Create written documentation describing which channel handles which source. Label your physical cables with painter’s tape indicating their destination. Set up your first Sunday scene with typical mic levels and a basic EQ starting point for your room.
Before your first service with the SQ-5, run a rehearsal with volunteers who will operate it. Have them practice muting and unmuting channels, adjusting faders, and recalling scenes. This builds confidence and ensures that technical issues won’t interrupt worship. The SQ-5’s intuitive design makes these basics straightforward even for newcomers to digital mixing.
Your Allen & Heath SQ-5 is now ready for reliable Sunday service operation. In upcoming articles, we’ll explore streaming audio routing, scene management for multiple services, and controlling the mixer remotely from an iPad using the SQ MixPad app.
