Choosing between the Allen & Heath SQ-5 and SQ-6 represents one of the most significant equipment decisions for growing churches. Both consoles share the same fundamental architecture, user interface, and reliability. The primary differences involve channel capacity, processing power, and network scalability. Understanding these differences helps you choose the right console for your current needs while anticipating your church’s growth trajectory.
Physical Size and Console Footprint
The most obvious difference between these consoles is their physical size. The SQ-5 is substantially more compact, fitting comfortably on standard control room furniture and requiring minimal space. For churches with limited control booth space or those planning portable setup for multiple services, the SQ-5’s compact size is a genuine advantage.
The SQ-6 is significantly larger, requiring dedicated counter space or custom console furniture. In fixed installations where space isn’t a constraint, this larger size provides tangible workflow benefits—more physical faders visible simultaneously, larger touchscreen display options, and less need for menu diving. However, if you operate your mixer from a cramped booth or move the console between services, the SQ-5’s portability wins.
Input Channel Capacity
The SQ-5 has 16 local mic preamps plus expansion through stage boxes and digital networking. For most mid-size churches running traditional worship bands with wireless vocals, instruments, and ambient coverage, 16 local inputs (plus a stage box when you need more) provide ample capacity.
The SQ-6 has 24 local mic preamps, accommodating larger worship bands, complex stage setups, and churches with multiple services or worship styles. If you run large contemporary bands with multiple keyboardists, additional guitar channels, click track, band communications, and high-quality overhead drum microphones, you’ll find the SQ-6’s expanded local input count valuable.
The critical question: Does your current setup push against the SQ-5’s 16 local inputs? Both consoles mix the same 48 input channels, so the difference is how many sources plug in at the console before you add a stage box. If you’re consistently using 14-16 local inputs, the SQ-6’s 24 provide comfortable headroom for growth.
Processing Power and Simultaneous Effects
Both consoles run the same 96kHz engine (a 48x36 processing matrix), so they have the same per-channel EQ, compression and effects. The SQ-6 doesn’t add processing power; it adds faders and local inputs.
If your worship aesthetic involves sophisticated effects chains—parallel compression, parallel reverb, complex routing—both consoles handle them the same way.
For most churches, the choice comes down to surface size and local inputs, not processing.
Monitor Mix Capability
Both consoles provide independent monitor mixes for stage performers. Both include 12 stereo mixes (usable as auxes or groups), plus 3 matrix mixes, enough for stage monitors and several additional mixes.
The SQ-6 doesn’t add mixes, but its extra faders make it quicker to work on independent mixes for lead vocalists, backup vocalists, musicians, choir, and additional monitor zones.
Networking and Expansion
Both consoles support dSNAKE and GigACE networking. The SQ-6’s larger architecture scales more gracefully to complex multi-location setups with multiple stage boxes and network audio infrastructure. For churches adding comprehensive digital audio networking, the SQ-6 provides more robust expansion possibilities.
The SQ-5 handles typical digital stage box deployments fine—one or two stage boxes with standard audio networking. If you anticipate growing to five or more networked devices or supporting multiple separate worship spaces simultaneously, the SQ-6 provides a more scalable platform.
Backup and Redundancy
If your church needs backup mixing capability, consider what happens when your primary mixer fails. An SQ-6 backup can cover for an SQ-5 in emergency—their architectures are fundamentally similar, and your shows transfer between them. However, recalling an SQ-6 show on an SQ-5 console requires some adjustment, as the channel counts don’t match.
Ideally, backup consoles match primary consoles, or you maintain two identical consoles simultaneously. For larger installations where mixing failure means service cancellation or serious problems, maintaining a second SQ-6 provides true redundancy.
Cost Considerations
The SQ-6 commands a substantial price premium over the SQ-5. This isn’t purely about size—you’re paying for expanded processing power, additional I/O, and more sophisticated networking capabilities. For churches with limited budgets, the SQ-5 provides exceptional value. For churches that can afford the SQ-6’s premium and genuinely need its expanded capacity, the investment yields years of reliable service.
Some churches start with an SQ-5 and upgrade to an SQ-6 after growth necessitates it. This staged approach spreads costs over time and allows your team to grow into digital mixing gradually. However, reselling used SQ-5 consoles can be challenging, so plan carefully if you anticipate upgrading.
Training and Team Knowledge
Both consoles share fundamentally similar interfaces and workflows. A team trained on the SQ-5 transitions to the SQ-6 easily. However, the SQ-6’s expanded options mean you have more advanced features available if your team develops expertise.
For churches with less experienced mixing teams, the SQ-5’s smaller surface actually helps learning. Fewer options mean fewer ways to accidentally create problems. As your team builds expertise, the SQ-6’s additional flexibility becomes more valuable.
Right-Sizing Your Console Choice
Choose the SQ-5 if: Your current worship setup uses 16 or fewer local inputs (or you’ll add a stage box), you have limited control room space, you value portability, you want the most cost-effective Allen & Heath digital console, or your mixing team is relatively new to digital mixing.
Choose the SQ-6 if: You regularly need more than 16 local inputs, you want more faders for sophisticated simultaneous monitor mixes, you have dedicated control room space, or you anticipate substantial growth in the next three to five years.
Your chosen console will serve your ministry faithfully for many years. Thoughtful selection now ensures you have the right tool for your current reality and reasonable growth. Both are excellent choices that deliver professional-grade audio quality to your congregation.
