MARSONA 1250 Programmable Sound Conditioner

A PRODUCT BY miarpac CORPORATION
Pioneers in sound conditioning since 1962
Marsona® 1250
Marpac Corporation, pioneer and innovator in sound conditioning for more than 30 years, has achieved a new level in personal environmental engineering with the Marsona® 1250 Multi Effect Sound Conditioner. The Marsona® 1250 emulates nature with state-of-the-art precision to capture the richest selection of the most soothing sounds the human ear has ever known.
Relax to the rhythmic beat of the ocean shore. Travel to the edge of a roaring waterfall or linger beside the playful splash of a babbling brook. Come home to the timeless sounds of summer – rain pouring on the roof, crickets and spring peepers in the field, evening bird songs.
With style, simplicity and technological elegance, the Marsona® 1250 offers you sound effects that can be tailored and molded to your shifting sound environment. Surf selections, for example, let you add an overlay sound of sea gulls and a bell buoy to the rhythm of the rolling surf. Other overlay effects include evening bird songs and the cadence of a country evening.
Marpac Corporation, integrating digital technology into an advanced, yet compact, sound conditioner foryour home, school or office, brings the soothing effects of nature to your fingertips – and to your ears.

POWER: Insert the 2.5mm x 5.5mm plug from power supply transformer (included).
ACCESSORY: Use for exterior speaker, headphones, etc. with 1/8 inch (3.5mm) monaural plug (no accessories included).
OVERLAY VOLUME: Rotating dial adjusts the volume of digitally recorded “overlay” sounds without changing the volume of the “base” or “background” sound. For instance, when on the 5.1 setting (SURF I with overlay of sea gulls and a bell buoy), rotating this dial can have the effect of making the gulls and bell buoy sound very close or very far away from your unchanging position on the beach. This dial controls the volume of:
Sea Gulls and Bell Buoy
Evening Bird Songs
Crickets and Spring
Peepers Babbling Brook

FUNCTION SELECTOR : You have 10 options, beginning with SURF I. Each touch of this button accesses the next selection. See “Sound Selections” chart.
L.E.D. DISPLAY: Illuminated display indicates the current function selected. An illuminated dot between the letter and the number indicates overlay sounds are activated. See “Sound Selections” chart. An illuminated dot in the lower right indicates that the TIME R is activated. The display will automatically turn off after three minutes, (except timer dot, if activated) so the light will not disturb you. To turn it back on, simply touch any button.

RANGE: Touch up arrow or down arrow to control the level of ambient sound between waves on all SURF settings and to control reso nance on all RAIN settings, using the same 0 to 15 scale. (NOTE: RATE and RANGE levels that you set for each function are stored in the memory of the Marsona® 1250, even when you turn your unit off. However, in the event of a power interruption, RATE and RANGE must be reprogrammed. You might want to make a note of your preferred settings.)
TIMER: Touch to program the Marsona® 1250 to automatically shut off after a period of 15, 30, 60 or 90 minutes. The small red light on the lower right of the L.E.D. will indicate that the timer is activated, and will begin to flash softly for three minutes before the unit turns off. For sleep we recommend leaving the unit on all night. It requires very little electricity and will help you sleep better.
