3.2. ADAPTING THE BLOW5 TO THE ROOM ACOUSTICS
Generally there are many factors affecting the monitoring of sound. For example, room size, distance from
the wall, size of studio space, the reflection of the room, and the distance between speakers and user. In a
multi-channel monitoring system like 5.1 surround or THX, a subwoofer is included in the system to produce
low frequency effect. So it may be necessary to reduce the low frequency level of the monitoring speakers.
Because of these various situations, the BLOW5 is able to be optimized to make the best of your monitoring
environment.
IMPORTANT NOTES
DO NOT place any obstacles that may block the flow of air. Air is the medium of sound. Refrain from using
reflective surfaces near the speakers. IE - glass, mirror or metal. PLACE THOSE MATERIALS AWAY FROM
THE SONIC PATH OF THE SPEAKERS.
Input Sensitivity Control
There are many types of devices to connect to the BLOW5. The unit can be set to correspond with the
varying impedances of third party devices. You can set the sensitivity to match with various kinds of input
sources. A visible scale/dB mark on the sensitivity control assists users in the correct setting.
Follow diagram shows input level scales. (Sound pressure level of output is 100dB.)
High Frequency Tilt Control
This switch adapts the BLOW5’s frequency
response to the dampening characteristics of the
control room. It tailors the overall high-frequency
response by beginning at 1.0 kHz, ±2 dB at about
10 kHz. You can use this switch to adjust
brightness of your speakers. It depends on room
conditions and the distance of speakers from the
user. The following graph shows how the treble tilt
affects the response of speakers.
