Introduction
The DaySequerra M2A-FM is the world’s best analog FM monitor complete with world-wide tuning and
de-emphasis settings. The M2A-FM measures your analog signal with digital accuracy, insuring that
readings will remain stable and reliable over time. Selectable measurement integration times let you
control peak reading for maximum modulation.
The M2A-FM includes a sensitive yet selective synthesized FM pre-selector with 20 presets so you can
quickly monitor other stations off the air. A high level input with built-in attenuator lets you connect
directly to a forward power RF port for greatest accuracy. RBDS Program Identification (PI) and Radio
Text (RT) fields are decoded and shown on the M2A’s Vacuum Florescent Display (VFD).
The M2A’s brilliant LED meters can be read from across the room. The upper meters measure stereo,
L+R, L-R and incidental AM noise. The lower meter measures positive and negative carrier deviation,
as well as pilot and SCA injection levels. 57kHz RBDS subcarriers can be accurately read to a
minimum level of 2.6 percent. An MPX output lets you connect external SCA demodulators.
The M2A-FM comes complete with six dry contact alarm relay outputs for loss of audio program,
carrier, pilot and RBDS as well as audio peak and over modulation, all with flexible settings for level
and duration.
