UREI 1603 TECHNICAL SUMMARY

CHANNEL INPUTS
Mic inputs are on balanced XLR connectors, while RIAA and Line inputs are provided on unbalanced RCA phono connectors. A ¼" TRS Insert jack is provided in the Mic path of Channel 1 to allow connection of external processing.

BOOTH OUTPUT
The Booth output is provided on both balanced XLR and unbalanced RCA phono connectors, and is controlled by the master Booth level control. A 'Mic Defeat' switch mutes the signal from the mic to the booth output to avoid feedback.

MASTER OUTPUT
The Master output is provided on both balanced XLR and unbalanced RCA phono connectors, and is controlled by the Master level control. A separate ¼" jack feeds a balanced mono sum of the master output signal.

Aux/FX LOOP
The send-and-return Aux/FX loop is supplied on unbalanced RCA phono connectors, and works in conjunction with the top panel Aux/FX level and routing controls.

PHONES SECTION
The front panel illuminated headphone output is supplied on both 1/4" jack and 3.5mm mini-jack connectors for total flexibility.

EXTERNAL MUTE FUNCTION
This contact port will mute all music channels except Mic input 1, to allow PA announcements. Useful for fire alarm systems.

POWER SUPPLY
The high quality internal PSU is fed via an IEC mains inlet, allowing a detachable mains cable to be used. A cable retaining clip provides total cable security. Universal power supply 100V - 240V AC. Consumption 50W max.
