Introduction; Connections, Operating And Display Elements - LD Systems IMA 30 Bedienungsanleitung

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 announ-
cements or emergency calls. With IMA® 30, LD Systems presents the first model of the new IMA® mixing amplifier-series, which leaves nothing to be
desired in terms of design and flexibility.
Seamless integration with IMA® 30 is a sure thing in both industrial and commercial applications thanks to the compact 9.5-inch housing design,
an array of connection possibilities, including Bluetooth for wireless connection of Audio and a multistage priority circuit. IMA® 30 is equipped with
four priority levels to manage all connected audio signals during emergency or priority announcements. An automatic standby mode can also be
activated to reduce power consumption during absence of audio signal.
The mixing amplifier features two priority contact closures: one for emergency input to mute both Mic/Line and music sources, and one for Mic/
Line Channels to mute music sources only. The outputs provide 30 W of power at 4 Ohm, a two-band equalizer for bass and trebles as well as 70
V/100 V tap settings. The Hi-Z and Lo-Z selector switch lets you separate the output signal completely from the output transformer to ensure an opti-
mal frequency response for low impedance applications. The built-in aux output can be used to add external power amplifiers, active subwoofers or
on-hold music systems to the IMA® 30. You can also choose to send the entire mix or only the selected music signal source to the aux output using
the music-mix selector switch.
FEATURES
• Line input for emergency signal with contact closure
• 2 microphone/line input sockets with microphone/line switch and switchable 24 V phantom power
• Switchable chime feature in Mic/Line 1 channel
• 2 line inputs with RCA (cinch) sockets and Bluetooth 4.0 interface (mono summed)
• Class-D amplifier with 30 W performance
• Output for low impedance speakers and 70 V/100 V outputs with LO-Z/HI-Z switch. The audio signal is completely separated from the transformers
for optimal frequency response during low impedance use.
• Balanced AUX line output for controlling external amplifiers, active subwoofers or music-on-hold systems
• Music mix switch on AUX out for setting whether AUX out plays the overall mix or only the selected music source.
• Separate tone control for treble and bass on the back of the device
• 4 priority settings for comprehensive integration options
• Switchable auto standby mode for reduction of energy consumption
• User-friendly control panel design for intuitive operation with capacitive control panels for selecting music source and for Bluetooth pairing
• Clearly arranged and labelled sockets and operating elements on the back for easy installation
• Universal wide-range switching power supply
• Half-rack format with 2 height units
• Rack mounting kit optionally available (IMA RK) for mounting one or two IMA 30/60 together in a single 19" rack.
