Frequently Asked Questions
What is an active DI box and why do I need one?
A DI box converts high-impedance instrument signals to low-impedance mic-level signals suitable for mixing consoles; active DI boxes have amplification for better signal quality.
What sources can connect to the AR-133?
The AR-133 works with instruments, keyboards, amplifier outputs, DJ consoles, and any high-impedance audio source.
When would I use the -20dB or -40dB attenuation settings?
Use attenuation for very hot sources like power amplifier outputs or high-level keyboard outputs to prevent clipping.
Does the AR-133 require phantom power or batteries?
The AR-133 features phantom-to-battery failover; it preferentially uses phantom power from your mixer but switches to battery if phantom is unavailable.
What does the ground-lift switch do?
Ground-lift eliminates hum caused by ground loop noise between the instrument source and mixer; use it if you hear buzzing.
Is the AR-133 durable enough for touring?
Yes, the rugged aluminium extrusion case is designed for road use and professional touring applications.
How quickly can the AR-133 be delivered to the UAE?
Procure.ae supplies across the UAE and GCC on a request-a-quote basis; contact for current lead times.
Can Procure.ae provide technical support for DI box setup and troubleshooting?
Procure.ae can discuss technical support and best practices; request a quote.
What power options does the AR-133 have?
The AR-133 supports phantom power from the mixer or battery power, with automatic failover between the two.
What attenuation options are available?
