DA-912 Digital interface module
BLOW5D is equipped with a DA-912 which is
a kind of digital interface module.
so, BLOW5D can be connected various digital inputs such
as AEU/EBU(XLR), S/PDIF(RCA) and RCA thru connector.
Amazingly, a D/A converter in DA-912 supports up to
24-bit/192kHz sample format with 123dB dynamic range.
If you want to upgrade BLOW5 to BLOW5D,
purchase DA-912 and insert it into a empty slot located
in the back of BLOW5.

BLOW5D powered near field studio monitoring speaker features
a two-way, bi-amplifier designed to achieve high quality sound.
The frequency response is broadened downward by using the bass reflex system, and broadened upward by a natural silk dome tweeter. Together they provide very delicate signal reproduction.
The speakers’ wide frequency response is also due in part to the design of its enclosure.
The analog input connector provides for an XLR balanced input
and a TRS 1/4” phone jack balanced or unbalanced input.
You can also adapt BLOW5D to your control room acoustics by the select controls on the back panel. As you set the units for your ears, they will prove to be more accurate than any other m nitoring speaker.
From professional users in commercial studios to home studio owners, BLOW5D is the true advanced solution for near field studio monitoring in its class.

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 BLOW5D is able to be optimized to make
the best of your monitoring
environment. |

There are many types of devices to connect to the BLOW5D.
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.
The above diagram shows input level scales. (Sound pressure level of output is 100dB.) |

This switch adapts the BLOW5D’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. |

If you’ve placed speakers close to the wall or in a corner, you’ll be hearing too much loud low frequency level.
In the case of some studios, there is bass-trap for reducing the low frequency level.
The Room Compensation Control allows you to lower the bass range depending on the room acoustics.
You can select the switch to reduce low frequency level in
3 steps of -2dB below 500 Hz.
The following graph shows how Room Compensation Control affects the response of the speakers. |

You can use this switch to adjust the bass roll-off in a multi-channel surround system, or to balance your room resonance.
A subwoofer makes a deep, low frequency sound.
You can mix how a sub and BLOW5D harmonize using the Cut-off Low Frequency Control.
Flat, -80Hz and -100Hz are the selections.
The graph shows how the Cut-off Low Frequency Control affects the bass response of the speakers. |
