The DualZDirect is a 2-channel passive direct box for connecting unbalanced instrument, line, or speaker signals to balanced inputs.
Each input signal is sent to a transformer-isolated XLR output and a parallel Thru jack so it can simultaneously be connected to an amplifier on stage.
Front panel switches engage up to 40 dB of attenuation to accommodate high-level signals, and a low-pass Bessel filter to eliminate high-frequency interference. Rear switches activate a ground lift to reduce hum, and invert the signal polarity to resolve phase issues, such as those which can occur when combining DI and mic sources.
As a fully passive design, the DualZDirect doesnt require an external power source. Passive DIs are often a great match for powered sources such as synthesizers or guitars and basses with active preamps.
Simple and durable, the DualZDirect is a compact DI in a rugged aluminum enclosure with two indpendent channels and a versatile feature set.

The Rane BB 22 Balance Buddy is a handy professional-grade tool used to provide isolation for and convert unbalanced -10 dBV consumer level RCA outputs up to balanced +4 dBu professional XLR inputs. The BB 22 converts one pair from -10 dBV to +4 dBu. There are two male XLR connectors and two RCA jacks.
Mackie MDB-1A, is great for active instruments like guitars and basses with active pickups and preamps. Featuring a 1/4" high-impedance input and thru with -20db pad plus a Merge switch that turns the Thru jack into a second input, perfect for summing a stereo source to a mono output. The balanced XLR output features switches for Polarity, Low Cut, and Ground Lift. For maximum convenience, the MDB-1A is powered by 48v phantom power.
Το DTI (Dual Transformer/Isolater) είναι ένα υψηλής ποιότητας παθητικό audio interface το οποίο διαθέτει ένα ζεύγος υψηλής απόδοσης μετασχηματιστών ωστε να διαχωρίζει εντελώς τις γειώσεις των σημάτων εισόδων και εξόδων , εξαλείφοντας ανεπιθύμητους θορύβους όπως hum και ground-loop . Οι μετασχηματιστές ήχου του DTI έχουν εξαιρετική απόκριση συχνοτήτων και μπορούν να χειριστούν μεγάλης έντασης σήματα διατηρώντας στο ακέραιο την balanced έξοδο. Αυτό δίνει στο DTI πολύ καθαρό και ουδέτερο ήχο σε πληθώρα σήματα πηγών .
