Two different priority levels can also be assigned to the connected Remote Microphones, depending on application. [Connection] Connect each Remote Microphone in series using the Category 5 STP cable and RJ-45 connectors.
  • Page 17 GENERAL PURPOSE BROADCAST REMOTE MICROPHONE Distance between Remote Microphone and VM Amplifier Using the specified cable, connect between the VM amplifier(s) and Remote Microphone(s) via their LINK connectors. They can be connected in any order. (Two connection examples are shown.) Connection example 1 Link cable LINK connector (RJ45)
  • Page 18 GENERAL PURPOSE BROADCAST REMOTE MICROPHONE Supplying Power from the VM Amplifier to the Remote Microphone The VM amplifier can only supply power to one Remote Microphone. Therefore, each of the remaining Remote Microphone(s) needs to have a 24 V DC power supply (AC adaptor) of its own. NOTE: When the RM-210 is used to expand the functions of the RM-200M, the power connections remain the same, however cable distances change.
  • Page 19 GENERAL PURPOSE BROADCAST REMOTE MICROPHONE Special Power Supply from the VM Amplifier to the Remote Microphone When building a system in which 2 or more Remote Microphones are to be connected to each of two VM amplifiers, a system that eliminates the necessity of an AC adapter for the first RM-200M connected to each VM amplifier can be created by modifying the link cable between the two VM amplifiers.
  • Page 20 GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD About the EV-200 The EV-200 digital sound source playback card for automatic broadcast is featured in the VM-2000 Series lineup. Using the optional card, emergency messages can be automatically broadcast or a chime tone sounded at preset times when using an external timer.
  • Page 21 GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD Message Activation Messages recorded on the CompactFlash memory card can be played back by activating (no-voltage "make" contact) the control I/O terminal located on the VM amplifier's rear panel, as in the case of the Remote Microphone.

  • Page 22: Voice Announcement Board

    GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD Recorded CF Card Messages Messages can be recorded on the CF card using the EV-350R. In the EV-350R, a series of messages is called a "program," which is called a "message" when played back using the EV-200 and VM amplifier. Up to 8 Messages (programs) are available, with Nos.
  • Page 23 GENERAL PURPOSE BROADCAST VOICE ANNOUNCEMENT BOARD Recording To install the EV-200 Voice Announcement Board in the VM amplifier and play back the message, prerecord the message on the CompactFash memory card using EV-350R. When the CF card is first inserted into the EV-200, a pilot tone is written in the card. When using the EV-350R unit for recording, leave the recording space of more than10 seconds.

  • Page 26: Expansion Functions

    GENERAL PURPOSE BROADCAST EXPANSION FUNCTIONS A Maximum System Employing a Single Master Amplifier In the VM amplifier system, the VM-2120 or the VM-2240 can be expanded as a sub-amplifier to increase the number of broadcast zones. Even in this case, the number of input channels and the EV-200's functions remain unchanged.
  • Page 27 GENERAL PURPOSE BROADCAST EXPANSION FUNCTIONS How to Connect 3 or More VM amplifiers When connecting 3 or more VM amplifiers, the following settings are required: (1) Master-sub relationship. (2) The number of units to be connected to the system (the total number of sub-VM amplifiers and RM units. The master unit is not included). (3) Unit number for each sub-amplifier.
  • Page 28 GENERAL PURPOSE BROADCAST EXPANSION FUNCTIONS The Number of Connectable Speakers Up to 5 broadcast zones can be selected with the VM-2120 and VM-2240. The VM-2120's maximum power output is 120 W, while that of the VM-2240 is 240 W. The following two patterns show the system where speakers of a total of 120 W are connected to the VM-2120 or speakers of a total of 240 W are connected to the VM-2420: Pattern 1: All speakers connected to 5 zones.

[Connection] Change the connection of the CN-1003 connector on the VM amplifier's RY circuit board from [2P-3P Short] position to the [1P-2P Short] position. Connect the BGM amplifier speaker output to the VM amplifier's External Speaker input.
  • Page 32 GENERAL PURPOSE BROADCAST EXPANSION FUNCTIONS External Standby Amplifier Operation A backup system for VM amplifier failure can be created by configuring the following system. [Operation] During a normal broadcast using two VM amplifiers (Fig.1), one of these amplifiers fails (Fig.2). The SV-200M in the failed amplifier sends failure information to the CPU inside the VM.
  • Page 33 GENERAL PURPOSE BROADCAST EXPANSION FUNCTIONS Standby Amplifier Connection In case of amplifier failure, they can be backed up by creating the following system. [Connection] Prepare a standby amplifier with the same output rating as that of the VM amplifier. Install the SV-200M in the VM amplifier and connect the PREOUT to the standby amplifier, and the standby amplifier's output to the VM amplifier's EXTERNAL SP input.
  • Page 34 GENERAL PURPOSE BROADCAST EXPANSION FUNCTIONS Operation Using Both Standby and Quasi-Dual-Origination Amplifiers The following system enables the same amplifier to provide both standby and quasi-dual-origination broadcast functions. Quasi-dual-origination broadcasts are normally made using both the VP-1120 or VP-1240 amplifier and the VM Series amplifier.
