Model 312-ME-AV
GENERAL DESCRIPTION
The TOA 312-ME-AV is a 3-way reference monitor with
numerous applications in small and medium size recording
studios, A/V houses, and control rooms of broadcast
facilities. Due to the magnetically "shielded" components us-
ed in the 312-ME-AV, the speaker enclosure may be phy-
sically located adjacent to color televisions and video
monitors with no degradation in video quality. (Magnetic
fields emitted by unshielded systems may cause distortion
and break-up of the video image, when the speaker is placed
in close proximity to a video monitor.)
The 312-ME-AV is a bass-reflex type enclosure, with a
11"(28 cm) woofer, a 4.7"(12cm) midrange cone speaker, and
a 1.2"(3cm) titanium dome tweeter, with diffuser for excellent
high frequency response.
A tight, symmetrical component arrangement ensures good
image localization for close-in monitoring, as well as smooth
frequency response, low distortion, monitoring, as well as
smooth frequency response, low distortion, wide dispersion,
and superb transient response.
The 312-ME-AV will handle a maximum of 135 watts of con-
tinuous program material. It features both a high frequency
attenuator and a mid frequency attenuator, both conveniently
located on the front panel, as well as push-type input ter-
minals and a removeable front grille. The wooden enclosure
is finished in charcoal gray vinyl sheeting.
