Hafler IRIS manual improper cartridge frequency-response, Iris With Cover Removed

Even if you are experimenting, you must replace the cover before re-plugging in the unit to AC-not only for safety reasons, but to shield hum and interference which can totally invalidate any attempts at sonic evaluation.

CAUTION:

When low value resistors are installed and automatically se-

lected by the high-gain MC position (button IN) of the PHONO- GAIN switch, accidentally using this setup for a HIGH OUTPUT cartridge can result in deceptively normaloutput levels, but with

improper cartridge frequency-response.
