Can it be used in a car?

At 19" wide and several inches deep, requiring a/c power, I can't envision a situation where it would be practical to use this product in a car. Also, electrical noise from car electronics would be a factor.

If using xlr to rca connector will it make noise?

rca connectors are typically noisy on any application.

Can the rack "ears" be cut off ? I have a very strict width limit

Any ears can be cut off, but I would be very careful. If you damage the corners, the integrity of the cabinet is gone.

How is this compare to dbx 1231? Which model make less electrical noise?

hum noise depending how you are feeding all your equipment, for the money I haven't had any noise issues but this is not a traveling rig, eb tec Hum ex units would be advisable as a back up

Silent in the signal path. Practically Transparent

Amazing 1/3 octave Graphic Eq. Very quiet in signal path.. no extra hum or hiss etc. Highly recommended compared to the Behringer which is much noisier/.

Ottimo prodotto

Ottimo prodotto che compensa la bassa qualità di casse e/o ampli soprattutto per quanto riguardae le basse frequenze. Bypassandolo e non velocemente utilizzando il tasto dedicato potrete apprezzare notevolmente la differenza generata dallo strumento. Consiglio vivamente l'acquisto

高音質ステレオセットに使える

プリアンプとメインアンプの間にチャンネルディバイダーの前段として設置。アウトプットレベル表示（-10〜+18dBu）とインプットゲイン調整（-12〜+12dB）のおかげでプリアンプ出力とメインアンプ定格入力レベルの設定が容易。31チャンネル最大+/-12dBのゲイン調整も必要かつ十分。ノイズレベルも十分低い。十分高音質のステレオセットに使える。
