Frequently Asked Questions - Core 250i QSC
How do I connect the Core 250i to my mixer?
Use balanced XLR cables from your mixer outputs to the analog inputs (channels 1-4) on the Core 250i. Ensure both devices are powered off during connection.
Can I use the Core 250i as a standalone DSP without Q-SYS?
No, the Core 250i requires Q-SYS software for configuration and control. It cannot operate as a standalone device.
How do I update the firmware on the Core 250i?
Connect the Core 250i to your PC via USB, then use Q-SYS Designer software to upload the latest firmware from the QSC website.
What is the maximum input/output level?
Maximum analog input level is +24 dBu; output level is +24 dBu into 600 ohms.
Why is the Core 250i not powering on?
Check the power cord connection and ensure the outlet is live. Verify the voltage switch (if present) is set to your region (100-120V or 220-240V). If still off, contact support.
How many channels can I process?
The Core 250i can process up to 8x8 channels internally, but analog I/O is limited to 4 inputs and 4 outputs.
Can I cascade multiple Core 250i units?
Yes, you can network multiple units via Q-SYS and synchronize them using Ethernet. Each unit operates independently but can be controlled from one design.
What is the latency of the Core 250i?
Latency is typically 1.6 ms at 48 kHz sample rate, measured from analog input to analog output.
How do I reset the Core 250i to factory settings?
Press and hold the reset button (small pinhole) on the rear panel while powering on. Release after 5 seconds. All settings will be lost.
Is the Core 250i compatible with Dante?
No, the Core 250i uses AES3 digital audio and Q-SYS network. Dante support is not available on this model.
