Now you can have the world’s best Analog FM monitor complete with world-wide tuning and de-emphasis settings at a competitive analog price. Then, whenever you’re ready, you can upgrade your unit to add full HD Radio™ capability.

DaySequerra is the leader in HD Radio™ monitoring, and every one of our HD Radio™ monitors starts with a superlative analog monitor section. 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 preselector 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 is decoded and shown on the M2A’s Vacuum Florescent Display (VFD). The M2A-FM comes complete with opto-isolated alarm outputs for audio peak, audio program, carrier loss and RBDS, with flexible settings for level and duration.

In addition to its accuracy and features, the M2A-FM gives you audiophilegrade Class-A biased audio outputs, so you can precisely monitor and adjust your processing. In addition to L and R analog outputs, the M2A-FM has a full-time digital output, so you can feed your AES monitoring chain, and a front panel headphone jack powered for uncompromised, full-quality audio.

The M2A-AM 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-AM includes a sensitive yet selective synthesized AM preselector 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. C-QuAM AM Stereo is standard on all units. 

The optional Ethernet Remote Control package comes bundled with DaySequerra’s Remote Dashboard™ software, a proprietary PC-based application that gives you 100 station scanning, remote control monitoring, logging and alarms with E-mail alarm notification

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, and also pilot and SCA injection levels. 57kHz RBDS subcarriers can be accurately read to a minimum level of 2.6 percent. A multiplex output lets you connect external SCA demodulators
