The device gives us is a BSS TRS especially since it is a dynamic qualiseur paramtrique. We all know what an EQ or compressor, and of the DPR-901 II uses just an expander / compressor instead of boost / cut of a traditional EQ.
Clearly, this is a mono 4-band EQ (2 band Stereo) coupled to a compressor (for tape, of course). O On the designation of qualiseur paramtrique dynamic.
The potentiomtres can contrller:
SETTING THE frquence-the cutoff,
SETTING THE-slctivit the filter (Q),
But no-rglage Cut / Boost. We find these parameters instead of a compressor that works in Comp / Expand. Clearly, a compress is frquence attnue (Traditional Cut) and an expansion is frquence boost (Gain Boost or a traditional EQ).
The advantage of this technique is clear: qualisation is applied according to the dynamics of the signal, making it much more efficient.
Of course, that 1 U rack is 100% analog and its I / O symtriques are on 3-pin XLR. It is also able to work with assymtriques connections and signals-10dB.
Users of EQ and compressors have the traditional hand in 5 minutes, others will practice using these two companions always ingnieur the sound ...
Anyway, the layout of controls and trs many LED indicator and Vu-Maître make using the device very simple trs.
The manual (in English) is also clear that full.
The DPR is a really good camera trs and its field of use covers large areas of trs. It is found in broadcast, or in Mastering Sound. Personally, I use it especially in combination Tracking o EQ / Compressor is a true gift from heaven ...
No doubt, it is effective and it rings.
I use a DPR-901 II for 4 years now and I did that two connate default:
-To use its full potential requires ... have a deuxime. A device can track a perfect track, but for full use in mastering, it is clear that 4-band Vallent much more than 2 (Stereo mode). And that's the default that the second shows the tip of his nose.
-The price. The technological excellence of BSS is not given.
It is a marvel of Swiss Army knife, but at the cost of a Rolex!
