4. REAR PANEL FEATURES

7. DC POWER SWITCH

If this switch is pressed in, the unit will automatically

switch to external DC battery power whenever (or if-ever)

your local AC power fails. You will need to connect an

external 24 Volt battery to the DC battery terminals (19).

If the switch is out, the battery will not power up the unit.

8. AUXILIARY SPEAKER TERMINALS

Use these terminals to connect

a small speaker to monitor the

AUX IN (16) Auxiliary input.

The unit has an internal 1 watt

amplifier to power the speaker,

and you can control the volume

with the rear panel MONITOR

VOLUME (12) level control.

9. PRIORITY TERMINALS

If these terminals are

connected together using an

external switch, the AUX IN

(16) input is attenuated and

the other inputs have priority.

10. TELEPHONE PAGING TERMINALS

These 600 ohm input terminals allow you to connect an

auxiliary input. Any signals present at these terminals take

voice priority over all other inputs. The volume is adjusted

using the rear panel TEL VOL (11) level control.

For a balanced connection:

T = Tip (Hot or "+")

R = Ring (Cold or "–")

G = Ground (Shield)

For an unbalanced connection:

T = Tip (Hot or "+")

G = Ground (Shield)

11. TELEPHONE PAGING VOLUME

This controls the volume of any signals connected to the

TELEPHONE PAGING (10) input terminals. Adjust it to suit

your taste, so any pages are heard clearly. Turn this down if

you are not using these input terminals.

12. MONITOR VOLUME

This control allows you to adjust the output level present at

the AUXILIARY SPEAKER TERMINALS (8).

13. AUX IN INPUT SENSITIVITY SELECTOR

This four-position slide switch lets you adjust the input

sensitivity of the AUX IN (16) to suit whatever source

device you have connected. The options are: CD, Tuner,

Tape, and Aux. Try each position, and find which sounds

best.

14. INPUT SENSITIVITY and PHANTOM POWER
SELECTORS

These three-position slide switches allow you to adjust

each of the four inputs to suit whatever you are connecting.

The positions are LINE, MIC and PHANTOM 24V.

LINE: select this if you are connecting a line-level signal.
MIC: use this if you are connecting a dynamic microphone.
PHANTOM 24V: use this if you are connecting a

microphone which requires phantom power (such as

condenser mics). The unit will supply 24 VDC on XLR inputs

pin 2 and pin 3.

Consult your microphone's documentation to see if it

needs phantom power. Take care as some microphones

can be damaged. Also, never use phantom power if you

have connected a line input using the XLR inputs. Do not

plug or unplug any microphones with the phantom power

on; turn it off first. Turn the front panel INPUT LEVEL

controls down before you turn the phantom power on.
