CONTROLS AND CONNECTIONS 2. CONTROLS AND CONNECTIONS 2.1 Front Panel 1, Socket MIC/LINE 1 Electronically balanced XLR-input on the front panel for the connection of microphones or other signal sources. This socket is connected parallel to the MIC/LINE 1 input on the appliance’s rear panel. Gain, Pad and phantom power settings have to be performed on the rear panel. 2, Sockets AUX 1 L/R The AUX 1 L/R RCA-type connectors on the front panel allow connecting a 2-channel audio signal source (e.g. CD-

CONTROLS AND CONNECTIONS 6, Tone Control LO / HI Each of the four MIC/LINE as well as each of the four AUX inputs has its own tone control section, which allows individually amplifying/attenuating the treble (HI) and bass (LO) by +/-15 dB. Turning the tone controls clockwise amplifies the corresponding frequency range, while turning them counterclockwise results in attenuating the corresponding frequency range. Avoid extreme settings. Generally, minor corrections of the input sound signal will a

CONTROLS AND CONNECTIONS 2.2 Rear Panel 14, 24 V power supply These two 6.3mm flat-connectors are utilized to supply the DRM 4000 with an operating voltage of 24 V DC. Whenever incorporating the DRM 4000 in an intercom system, using the system’s already existing supply voltage of 24 V is recommended. For stand-alone operation use the optionally available mains adapter (NRS 90257). Make sure to mind the correct polarity (+ = +24V, - = Ground) when connecting the power supply. 15, REMOTE INTERFACE

INSTALLATION AND CONNECTIONS 4. INSTALLATION AND CONNECTIONS 4.1 General Notes Achieving the best results possible with your DRM 4000 is only doable when making sure that all connections are in perfect order. For operating the appliance, connect its power supply via the flat-con- nectors on the rear panel to a 24 V DC power source. When incorporating the DRM 4000 in a PA or intercom system, using the already present 24 V supply voltage is recommended. For including the DRM 4000 in other applicat

INSTALLATION AND CONNECTIONS 4.2.2 AUX and MIX IN inputs The four AUX-inputs (2 and 23) and the MIX IN-input (21) are provided via RCA-type jacks, which allows the direct connection of common unbalanced audio equipment (CD-Player, Tape Deck, Tuner, etc.). Usually, the needed connection cords are supplied together with the corresponding device. They are also available at basically any electronics store. Especially when using unbalanced cables, cable length matters: the shorter the cable, the smal

INSTALLATION AND CONNECTIONS 4.4 Control Inputs 4.4.1 CONTROL INPUTS The CONTROL INPUTS (16) are eight freely configurable control inputs, which are provided via Phoenix-type terminals on the rear of the appliance. Closing (connection to ground) a control contact switches to the corresponding configuration (preset). Simultaneously closing several contacts selects the preset with the highest priority setting. When all control inputs are open (idling mode), the DRM 4000 is set to its BASIC CONFIGU

INITIAL OPERATION 5. INITIAL OPERATION 5.1 Power-On Operation The POWER-switch (12) switches the power of the DRM 4000 on. The ON-LED (13) starts to light and after a short period of initialization (approx. two seconds), the DRM 4000 is ready for operation. When switching the DRM 4000 on for the first time, it is factory-pre-configured for 8-in-2-mixer operation. If the appliance had previously been operated, it may start-up in another configuration. Make sure to set the MASTER A / B volume con

INITIAL OPERATION NOTE: If the input signal is not present at the master outputs, check the following: • Are the master controls (10) open? • Has the corresponding MIC/LINE input been assigned to one or both output channels? Please mind and compare your actual setting and the selected configuration! • Is ducking control active (see ducking indicators (9)) and does this maybe affect your input signal? 5.2.2 Level Adjustment for AUX-inputs The four AUX-inputs are provided via two unbalanced RCA

SPECIAL FEATURES OF THE DRM 4000 6. SPECIAL FEATURES OF THE DRM 4000 6.1 Using Ducking Control The ducking control allows the unaltered passage of audio signals of prioritized channels (MIC/LINE 1 and / or MIC/LINE 2), while at the same time the audio signals of any other non-prioritized input channels (e.g. background music) are attenuated to a pre-adjustable level value. The background music audio signal fades in smoothly upon finishing the announcement. For using the ducking function, you hav
