Model: V-1812C

Type: User manual

Optimus V-1812C is a versatile active monitor module designed to enhance your audio monitoring experience. With 12 input channels, it allows you to monitor both 1V AC and 100V AC signals, providing flexibility for various applications. The built-in speaker and headphone jack offer convenient monitoring options, and the volume control lets you adjust the audio level to your preference. The 7-LED bar graph provides visual indication of the signal level, ensuring accurate monitoring.

INSTRUCTION MANUAL

ACTIVE MONITOR MODULE V-1812C

? GENERAL DESCRIPTION

Designed for use with TOA’s V-1000B Mixer Frame, the V-1812C can monitor up to 12 speaker lines (100V) or line level

(1V). A switch on each input selects either 100V / 1V operation, allowing mixed signal monitoring on a single module. A

rotary switch allows selection of the input line for monitoring by a 7-LED bar graph and internal speaker. A headphone

socket is provided which can disable the internal speaker when used (depending on internal jumper setting). A volume

control is provided to adjust the speaker / headphone level.

? APPLICATION

Select the channel to be monitored with the channel selector ( ). The selected channel’s level will be displayed with the

5-segment LED bar graph ( ). The signal can be monitored by the build-in speaker and the volume can be controlled with

the volume control ( ). When plugging in a headphone into the headphone socket ( ) the speaker will be

switched off.

An external speaker can be connected at the pins 14 (HOT) and R (COM, ground). If it shall be driven together with the

build-in speaker then its impedance must be 8 ohms or higher. The internal and external speaker can be switched on and

off by a control signal, which speaker will be switched on or off depends on the setting of jumpers J13. If the external

speaker is to be driven without the build-in speaker then disconnect the build-in speaker by unplugging the connector "XL"

on the PCB board. The impedance of the external speaker must be 4 ohms or higher if the internal speaker will not be used

together with the external speaker, otherwise it must be 8 ohms or higher.

? INSTALLATION

Remove the mixer frame rear panel. Cut bus wires

to replace the original circuit board connector with

the supplied 44-pin card-edge connector, as

illustrated in the figure. Make internal connections

and replace the rear panel. After plugging the

module in the frame, secure the module with 4

screws.

? SETTINGS

Setting of Sensivity

The input sensivity can be selected either 1 VAC or 100VAC by setting

the jumpers 1 ~ 12. Set the jumpers on right or left position, as illustrated

in the figure (view on part side of PCB, connector on right side).

Setting of Relay Function

The activation of the internal and the external speakers can be controlled by the control input depending on the settings of

the jumpers J51-1/2/3/4 ( ). For setting refer to following list:

Jumper Setting Control

J51-1 speaker(s) OFF

J51-2 speaker(s) ON

J51-3 switch over to external speaker

J51-4 switch OFF internal and external speaker

Set jumpers either to 1 or2, and to either 3 or 4.

The external control is made via pin 20 by making a contact to ground.
