Rion UN-14 Measuring Amplifier/Sound Level Meter Unit

The UN-14 can be used with a wide range of microphones and it can either be used on its own or as part of an up to 16 channel (sound or sound & vibration) system controlled by the UV-22. It supports CCLD and TEDS compliant microphone pre-amplifiers and the direct microphone input supports measurement microphones which require 0, 30, 60 and 200V polarisation voltages. The UN-14 has a clear backlit display which shows level (as both numeric and a bar graph display) and important measurement parameters including time and frequency weighting.

  • Fast, slow and 10 msec response
  • A, C and Z (flat) frequency weightings
  • 1 80 kHz frequency response
  • Wide range of microphones supported (CCLD, TEDS, Condenser Mics with 0V, 30V, 60V and 200V polarisation voltages)
  • Analogue a.c. and d.c. outputs
  • TEDS, CCLD inputs and separate a.c. and d.c. outputs via industry standard BNC sockets on rear panel
  • Output available via LAN or USB when used with UV-22
  • Dynamic Range 85 dB or more (20Hz 20kHz) [80 dB or more (1 Hz 80 kHz)] for a.c. output
  • 6 level range settings
  • Numeric display with 1 second refresh rate
  • Bar graph display with 100msec refresh rate
  • 20Hz hi-pass and 20kHz lo-pass filters (can be independently switched in or out)
  • Additional hi and lo pass filter frequencies available when used with UV-22
  • Power supply 9 15V d.c. (12V nominal) via suitable adapter or Battery Unit BP-17
  • Resume function memorises all settings at power off and restores them at the next power on
  • Fast, slow and 10msec response
  • 1 20 000 Hz frequency Range
  • 50 dB dynamic range and it can either be used on its own or as part of an up to 16 channel (sound or sound & vibration) system controlled by the UV-22.
  • 0.01 30 mm/s paper speed
  • Dynamic paper speed control increases paper speed by a factor of 10 above a user-selectable trigger level (operates on base paper-speeds of up to 1 mm/sec i.e. increases paper speed up to a maximum of 10 mm/sec)
  • Battery-powered or external 12V supply
