Model VM88 Owner's Manual
(1) INPUT 1 ~ 4 connectors
Two types of connectors - Canon connectors (XLR-3-31 type) and TRS phone jacks - are provided for INPUT 1 ~
4 and either can be used to input of signals depending on the application. Refer to < NOTES > below.
Canon connectors that comply to mic/line levels and microphones are connected here in most cases. Condenser
type mics requiring phantom power can be connected because phantom power is provided to these connectors.
Also, you can trim within a range of -50dBu ~ -10dBu to match the equipment connected.
Line level sound sources can be plugged into the TRS phone jacks, which complies to both TRS type and common
phone plugs. The same as with the Canon connectors, trim is possible within a range of -30dBu ~ +10dBu to
match the output level of the equipment connected.
< NOTES >
* The Canon connector and TRS phone jack of each channel cannot be used in parallel. Use either input only.
A malfunction could occur if both are used at the same time.
* Be sure to switch off the power to the VM88 or switch off the phantom power when plugging or unplugging
microphone cables.
* Do not switch on the phantom power when using a dynamic mic. This could damage the microphone.
< NOTICE>
When using condenser microphones that require phantom power, first check "On/Off setting of phantom
power" explained later in "Setup mode" (Initially set at off). For details, refer to "Setup mode" on page 33.
(2) INPUT 5 ~ 8 connectors
INPUT 5 ~ 8 are TRS phone jacks and line level sound sources can be plugged in here. The input mode (stereo
or monaural) of the input connectors INPUT 5-6 and 7-8 can be changed depending on the application. Initially,
the input mode of INPUT 5-6 and 7-8 are set to stereo.
The input jacks comply to both TRS type and common phone plugs, and just as with INPUT 1 ~ 4, the input level
can be trimmed within a range of -40dBu ~ +4dBu to match the output level of the equipment connected.
< Please remember! >
The input mode (stereo/mono) of INPUT 5-6 and 7-8 can be changed to match the application. Initially,
they are set for stereo and thus stereo signals can be input to INPUT 5-6 and 7-8.
For example, if INPUT 5-6 are set to mono, the INPUT 5 jack will be effective and a signal input to INPUT 5
will be simultaneously sent to channels 5 and 6. For details on setup of the input mode, refer to "Setup
mode" on page 33.
