Tape Out (14); Master / Slave Din Socket (17); Ground And Earth Connection (19); Override (20) - Optimus PM-CH7 Manual De Instalación Y Funcionamiento

PM-CH7
Preamplifier
In case of not using this function, the bridge between these connectors must be kept.

4.6. TAPE OUT (14)

2 x RCA audio output for tape recording. Unbalanced 350 mV signal level not adjustable by
Master volume potentiometer.
4.7. MASTER OUT (15 & 16)
Master controlled main audio output. 1 V signal level.
2 x RCA connectors for unbalanced master output signal and XLR connector for balanced
master output signal.

4.8. MASTER / SLAVE DIN SOCKET (17)

Expansion connector used to link two units thus allowing the use of up to 14 channels.
With MASTER / SLAVE slide switch to define master unit and slave unit, the slave unit is an
extension of master unit. The highest priority state of slave unit equals to the music source of
master unit.
The slave unit has its own priority state of each signal. We suggest using slave unit music
source connector for music source. Then the master and slave unit can construct a 14 step
down priority function.

4.9. GROUND AND EARTH CONNECTION (19)

In all loudspeaker systems it is very important to have a single connection point between
ground and earth.
If there is more than one unit in the system, they will probably be linked either through the
power supply ground terminal or rack frame.
If ground signals are also connected through the circuits, it is advisable to remove the jumpers
between the signal ground and the frame of all units except one.

4.10. OVERRIDE (20)

This dry contact terminal closes when TEL / ERMER priority input is activated.

4.11. POWER SUPPLY 24 V DC (21)

24 V DC adapter input terminal.

4.12. BATTERY CONNEXION 24 V DC (22)

24 V DC Battery input terminal.
