Description DualZDirect2-Channel Passive Direct Box 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 PDB doesn’t 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.Features 2 Independent Channels 1/4″ TRS Inputs and Thru Connectors Balanced XLR Outputs Switchable Attenuation (-20 dB, -40 dB) per Channel Switchable Low-Pass Filter, Ground Lift, and Phase Invert per Channel Passive Design – No Power Required SpecificationsActive or Passive PassiveInputs 2x 1/4″ TRSOutputs 2x XLR2x 1/4″ TRS ThruInput Impedance 50 kΩOutput Impedance 600ΩControls Attenuator (0 dB, -20 dB, -40 dB)FilterGround LiftPhase Invert (All per Channel)Filter 30 kHz Low-PassFrequency Response 10 Hz – 50 kHz /- 0.5 dB @ 4 dBuTotal Harmonic Distortion .01% @ 1 kHz, 18 dBu (Typical)<.05% @ 100 Hz, 18 dBuChannel Separation >80 dB (Typical)Dimensions (HWD) 1.85″ x 4.6″ x 3.9″, 4.7 cm x 11.7 cm x 9.9 cmWeight 0.88 lbs / 400 g
