USING THE Pro-ISO
All Radial Engineering products are designed for simple, straight-forward use.
However, attention taken during set-up will ensure success. Before connecting
ensure the sound system is turned off and all levels are set to zero. This will
avoid any pops in the sound system that could cause damage to speakers,
headphones or your ears.
Confirm the recessed LEVEL control is set at its maximum clockwise position
and the LIFT switch is pushed inward. The Pro-ISO is completely passive and
does not require a power supply of any kind to operate.
1. Connect the ba4dB audio source to the XLR inputs using balanced
cables.
2. Use unbalanced cables to connect the outputs to the destination audio device.
Unbalanced cables should be kept under 20 feet in length to maintain the
best fidelity.
3. To confirm audio quality, you should monitor the destination audio device with
a set of headphones or a stereo loudspeaker system.
4. Turn the source audio level up slowly and listen for noise. In the event you
encounter hum or buzz, simply depress the ground lift switch.
5. Bring the source audio up to unity-gain. If the sound is distorted (clipping) turn
the LEVEL control down. You are now set to go!
