Page 14 Notice! Before mounting the device, it is recommended to make the required settings. The U Series mixer amplifiers and power amplifiers have four mounting options. Stand-alone mounting in a 19"-rack The mixer amplifiers and power amplifiers can be fitted alone in a standard 19"-rack. Mount one short rack ear to the preferred side of the device using the build-in screws.
Page 15 If you intend to use the full 19"-rack, you can stack two amplifiers in one rack slot. The U Series devices can also be mounted with a V600:2 side-by-side. U Series and V Series have the same side-by-side mounting system. Power amplifiers can be mounted together with mixer amplifiers.

This selection ensures seamless integration with emergency communication systems, facilitating clear and effective announcements during critical situations.
Page 25 U Series Installation | en The amplifier mode configuration allows you to fine-tune the amplifier operation to match their specific requirements. In HiZ mode, you can choose between 70 V and 100 V operation, ensuring seamless integration with high-impedance speaker systems. In LoZ mode, you have the flexibility to select between 4 ohm and 8 ohm operation, catering to low-impedance speaker setups.
Page 26 | Installation U Series High-pass filter activation Enabling the high-pass filter (HPF) activates a 120 Hz high-pass filter, effectively filtering out low-frequency signals from the audio output. This feature is particularly useful in applications where clarity and fidelity are paramount, ensuring that only desired frequencies are reproduced while eliminating unwanted noise or rumble.
