QSC SPA-Qf 60x2 – Two-Channel Q-SYS Network Amplifier with Flex I/O

Product Overview

The QSC SPA-Qf 60x2 is a two-channel Q-SYS network amplifier designed to extend the connectivity of Q-SYS Core processors into smaller rooms, distributed zones, and edge locations where the full power of the CX-Q Series is more than required. Delivering 60W per channel (120W bridged at 8Ω, 70V, or 100V), the SPA-Qf 60x2 is suited for small conference rooms, huddle spaces, breakout rooms, and individual zone fills where modest power levels are appropriate. Two onboard software-definable Flex channels — configurable as mic/line inputs with 48V phantom power or as line outputs — provide I/O flexibility at the amplifier without requiring a separate QIO expander. Four bi-directional GPIO pins enable local control panel LED indicators, occupancy sensors, or mute buttons.

The SPA-Qf 60x2 occupies a 1U half-rack footprint and ships with mounting hardware for rack, wall, or furniture installation — making it practical for under-display, in-millwork, or satellite rack deployments where a full 2U CX-Q chassis would be impractical. Convection cooling eliminates fan noise in noise-sensitive spaces. Like all Q-SYS network amplifiers, it integrates natively into Q-SYS Designer Software as a managed device on the Q-SYS network.

Key Features

• 2 amplifier channels at 60W/ch (8Ω and 4Ω); 120W bridged — Right-sized power for small rooms, zone fills, and edge amplifier locations where 500–1,000W/ch is excessive.
• Low-Z, 70V, and 100V bridged output support — 120W at 70V rms and 100V rms in bridged configuration for distributed speaker line compatibility.
• 2 software-definable Flex channels — Each channel independently configurable as mic/line input (with 48V phantom power) or line output via Q-SYS Designer Software; no hardware jumpers or DIP switches.
• 4 bi-directional GPIO pins + 3.3V power pin — Powers and monitors control panel LEDs, touch sensors, and external mute switches directly from the amplifier without a QIO expander.
• 1U half-rack form factor with multiple mounting options — Included rack/wall mount kit enables rack, wall, furniture, or under-display installation.
• Convection cooling (fanless) — Silent operation for noise-sensitive spaces including boardrooms, huddle rooms, and executive suites.
• Native Q-SYS integration — Full signal routing, gain, muting, metering, and Flex/GPIO configuration managed from the Q-SYS Core without separate amplifier software.
• Universal PSU with PFC; 100–240 VAC — Global compliance; power factor correction for efficiency.

Typical Applications

• Huddle room
• Small conference room
• Breakout room
• Commercial meeting space (small format)
• Distributed zone fill (edge amplifier)
• Under-display or millwork amplifier installation
• Government space (small office or breakout)

Frequently Asked Questions

How does the SPA-Qf 60x2 differ from the CX-Q Series amplifiers?
The SPA-Qf 60x2 is a lower-power (60W/ch), two-channel, half-rack amplifier designed for small rooms and edge locations. The CX-Q Series are full 2U rack-mount amplifiers starting at 500W/ch with four or eight channels, designed for medium to large commercial speaker systems. The SPA-Qf 60x2 is frequently deployed alongside CX-Q amplifiers — the CX-Q handles main and fill zones, while SPA-Qf units drive smaller breakout rooms or satellite spaces from the same Q-SYS Core processor.

What does the Flex channel do, and when would I use it as an output vs. input?
Each Flex channel can be independently configured in Q-SYS Designer as either a mic/line input (with 48V phantom power for condenser microphones) or a line output. Use as an input when a local microphone or line source needs to enter the Q-SYS network at the amplifier location without routing back to a QIO expander. Use as an output when a line-level signal needs to be distributed to an adjacent zone controller, recording device, or conferencing codec.

Can the SPA-Qf 60x2 be wall-mounted without a rack?
Yes. The included mounting kit supports rack installation (half-rack, 1U), wall mounting, and under-display or furniture integration. This makes the SPA-Qf 60x2 practical for installations where a rack is not available — such as behind displays in small conference rooms or huddle spaces.
