The Brüel & Kjaer 2610 Measuring Amplifier is a precision instrument for sound, vibration, and voltage measurements across laboratory and industrial environments. It operates as a standalone unit or as a core component in multi-instrument measurement systems, delivering true RMS indication with selectable gain and filtering for detailed signal analysis.
## Technical Specifications
**Frequency Response:** 2 Hz to 200 kHz (±0.5 dB flat response); extended range 0.1 Hz to 200 kHz with user-selectable high-pass filter at 22.4 Hz.
**Voltage Measurement Range:** 10 µV to 30 V full scale deflection (FSD) in 10 dB selectable steps. Extended to 100 µV to 300 V with 10:1 input probe.
**Gain:** Selectable from −30 dB to +100 dB.
**Input/Output Impedance:** 1 MΩ input; 50 Ω output.
**Analog Outputs:** AC recorder output at 1.6 V; DC output at 5000 mV ±10 mV.
**RMS Measurement:** True RMS for AC signals with crest factors to 10 (up to 20 below FSD). Averaging modes: Fast, Slow, and 20 s selectable.
**Peak Detection:** Maximum peak indication for pulse durations ≥25 µs.
**Input Overload Rating:** Withstands 220 V RMS (400 V peak including DC offset) without damage.
**Microphone Polarization:** 0 V, 28 V, and 200 V switchable.
## Key Features
• Built-in filtering: 22.4 Hz high-pass (30 dB/octave), A-weighting network, and 22.4 kHz low-pass (30 dB/octave)
• Dual input connectors: standard coaxial for direct voltage/vibration signals; 7-pin for Brüel & Kjaer microphone preamplifiers
• Interchangeable meter scales for sound, vibration, and voltage measurement modes
• Automatic indication of measurement range, gain setting, and overload status via LED lamps
• Remote switching capability via dual multipin sockets
## Typical Applications
• Precision sound level measurement with Brüel & Kjaer 1/2-inch condenser microphones and preamplifiers
• Vibration signal acquisition and conditioning
• Laboratory-grade voltage measurement and analysis
• Multi-point measurement systems requiring signal amplification and filtering
## Compatibility & Integration
Conforms to IEC 651 (Type 0), DIN 45633 (Part 1), and ANSI S1.4-1983 (Type 1) when configured for sound measurement. Direct integration with Brüel & Kjaer measurement chains via standard coaxial inputs and preamplifier sockets.
