Introduction; Connections, Controls And Display Elements - LD Systems IMA 60 Manual De Usuario

INTRODUCTION

Permanent installations require solutions which offer a visually discrete design that blends into the background while still being flexible and
versatile in their functions. You need to be able to connect different audio sources and manage them, to mute non-priority signals during
announcements or emergency calls. With IMA® 60, LD Systems presents another model of the new IMA® mixing amplifier-series, which leaves
nothing to be desired in terms of design and flexibility.
Its compact design, with 9.5" housing, versatile connection options including Bluetooth for the wireless connection of music sources and multi-
stage priority switching guarantees seamless integration in commercial and industrial uses. The IMA 60 offers four priority levels for emergency
calls and microphone/line inputs for various signal and music sources. Optionally, an automatic standby mode can also be activated in order to
further reduce energy consumption.
The mixing amplifier is equipped with two priority contacts: one for the emergency input, which mutes all other device signal sources, and one for
the microphone inputs, which mutes the music signal sources. The outputs provide a power of 65 W at 4 Ohm, a 2-band EQ for bass and treble and a
70 V/100 V tap. A low-Z/high-Z selector completely separates the output signal from the output transformer, in order to ensure the best frequency
response for low impedance applications. The IMA 60 can also be used with external amplifiers, sub woofers or music-on-hold systems via the
integrated Aux output. The music mix selector can be used to determine whether the entire mix or only the selected music source is sent to the
Aux output. The intuitive design of the control panel with capacitive buttons for the selection of the music signal source, the clarity of the rear panel
and the compact 9.5" format ensures that the mixing amplifier can be easily installed.
FEATURES
• Line input for emergency signal with contact closure
• 2 Mic/line input terminal blocks with microphone/line switching and switchable 24-V phantom power
• Switchable chime function in mic/line channel 1
• 2 line inputs with RCA sockets plus Bluetooth 4.0 interface (mono summed)
• Gain control and clip LED indicator in the input channels emergency and mic/line 1 and 2
• Class-D amplifier with 65 W power
• Output for low impedance speakers and 70/100 V outputs with LO-Z/HI-Z switching. In low impedance operation, the audio signal is completely
separated from the transformers for optimal frequency response.
• Balanced AUX line output for the connection of external devices (amplifier, active sub woofer, music-on-hold system)
• Music mix button to select the signal transmitted via AUX output (full mix, or selected music source)
• Separate tone controls for treble and bass on the back of the device
• 4 priority settings for versatile integration options
• Switchable auto standby mode to save energy
• User-friendly control interface - intuitive operation via capacitive controller (choice of music source and Bluetooth pairing)
• Easy installation thanks to the clear layout and labeling of the connections and controls on the back
• Universal wide-range switching power supply
• Format: Half rack width, 2 HE
• Optional: Rack assembly kit (IMA RK) for the installation of one or two IMA 30/60 units in a 19" rack
