• Design: Utilizes a complementary-symmetry amplifier design topology. It delivers up to 60 amps of current, allowing it to dissipate high heat loads during demanding live or studio use.
• Controls & Connectivity: Features a bridge-mono switch, XLR and 1/4" inputs, alongside banana jack and raw cable outputs.
• Build: Known for its "tank-like" heavy construction and standard rack-mount chassis.
Mackie FR M-1400 $250
Key Specifications
• Power Output (Stereo):
o 300W per channel @ 8 ohms
o 500W per channel @ 4 ohms
o 700W per channel @ 2 ohms
• Power Output (Bridged Mono):
o 1000W @ 8 ohms
o 1400W @ 4 ohms
• Weight: ~40-45 lbs (heavy, all-steel 2U chassis)
• Cooling: T-Design cooling tunnel with variable-speed fans
Notable Features
• Fast Recovery Circuitry: Keeps the amp stable and prevents "latching" or harsh distortion when pushed to its limits.
• Built-in Processing: Includes a switchable subwoofer crossover (63Hz/125Hz) and sweepable HF horn compensation for CD horns.
• Filters: Variable low-cut filters (10Hz-170Hz) to tailor your low-end response.
• I/O: Balanced XLR and 1/4" inputs, with Speakon® and binding post outputs.
Peavey CS-400 $95
Key Specifications

o 850W 8 ohms
Key Features
• Fast Recovery Circuitry: Reduces distortion and clipping when the amplifier is pushed hard.
• Built-in Subwoofer Crossover: Switchable low-pass crossover at 63Hz or 125Hz.
• Sweepable Low-Cut Filters: Variable from off up to 170Hz to protect woofers and tighten bass response.
• Constant Directivity (CD) Horn EQ: Sweepable HF compensation (2kHz – 6kHz, +6 dB/octave) for compression drivers.
• Cooling: "T-Design" constant-gradient cooling tunnel to keep output devices at a uniform temperature.
• Limiters: Channel-independent built-in limiters with a defeat switch.
• Metering & Indicators: Detented input controls calibrated in dB and volts; separate LEDs for OL (overload), signal present, and temperature.
Connections & Design
• Inputs: Balanced/Unbalanced 1/4" TRS and XLR, plus XLR Thru connectors.
• Outputs: Heavy-duty 5-way binding posts and 1/4" jacks.
• Form Factor: 2U rackmount design.
