Z-Direct
Passive
Direct Box
High-quality
passive
interface lets you
connect instrument,
line, or speaker level signals
to a mixer or other balanced input. High impedance,
single-ended (unbalanced)
1
⁄4" input is converted into
an isolated, balanced low impedance signal source.
The internal audio transformer has extremely flat
and wide frequency response and can handle high
signal levels. Input-attenuator switches allow
selection of 0dB, -20dB or -40dB for a wide range of
signal levels and the input-thru jack allows tapping
off of the signal chain. The ground-lift switch
separates input and output signal grounds to isolate
two systems, reducing hum and ground-loop noise.
Additional features: •Switchable 30KHz low-pass
bessel filter to cut out high frequency RF and
electrical interference •Phase invert switch •Compact
black anodized aluminum case Specifications:
•Frequency response: 10Hz~50KHz •THD: 0.01%

Eight– Channel
Ground Loop Isolator
Passive audio isolator utilizes eight high quality
transformers to separate input and output signal
grounds, thus reducing hum and ground-loop noise.
The transformers have flat and wide frequency
response and handle high signal levels while
maintaining an isolated balanced output. Each is
wound 1:1, for unity gain and are designed to be used
with impedances from 600~100,000ohm. It fits easily
into virtually any audio system and is a clean patch
point between all types of equipment, providing
balanced XLR,
1
⁄4" phone, and RCA type phono
connections on all inputs and outputs. The mounting
ears are reversible, allowing the XLR connections on
the front or the
1
⁄4" and RCA phono jacks on the front.
Completely passive design requires no power and
occupies only one rack space. Specifications:
•Frequency response: 10Hz ~50KHz •THD: .01%
•Channel separation 90dB •Phase error: <5°,
20Hz~20KHz •Insertion loss: 0.4dB @ 100Kohm,
5.5dB @ 600ohm •Dimensions: 1.75" (H) x
19" (W) x 3.75" (D)

accepts stereo
line level input,
mixes it with a
balanced mic input,
and provides stereo
headphone output.
Parallel “Thru Mic”
output allows easy insertion into existing PA
system. This is ideal for studio or stage use,
where a performer desires to hear his microphone,
combined with the overall mix, through headphones.
Independent level controls for the line and mic in
allow easy mix adjustment. Thru Mic output will
pass phantom power, and is unaffected by mix
settings. Specifications: •Line input:
