REAR CONNECTIONS AND ADJUSTMENTS B
A – Fuse holder (2 X 230V 2AT). B – Connection via standard IEC socket (cable supplied). Prima di collegare l’apparecchio verificare se la tensione indicata A
BALANCED/UNBALANCED INPUTS Use MIC.-AUX from 1/8 sockets for microphone and auxiliary connections.
Balanced functioning 3 wires: Pin 1 – Ground / Shield Pin 2 – Hot (+) Pin 3 – Cold (-)
Connect to Mic/Aux 1-8 inputs audio microphone signal or any other unbalanced device. 2 wires only:
Two possibilities are available: • Connection nr.1: Bridge PIN 1 & 3 Hot (+) PIN- 2 Hot (+) •
Connection nr.2: Use PIN 2 & 3 only. (2 Hot, 3 cold).

PHANTOM POWER Enable/Disable phantom power. Phantom 48 volts on microphone inputs (1-8)
Enable just the inputs which need to be powered. PHANTOM, set in the ON position and the relative numbered dip switches.
OUTPUTS / INPUTS
1 - LINK OUT / IN The Link In-Out (1) allows anti-feedback and/or equalizer connection in between the Mixer section and the power amplifier section.
The audio signal of the 8 Mic-Aux inputs, when prearranged, can be directed even just to the L o R (4) outputs.

315-308-4860
2 - AUX 1 (9/10) INPUT
Use this input to connect radio microphones, liturgical players, electronic organ, CD player, CD/DVD recorder-player.
2 - AUX 2 INPUT (11/12)
Use this input to connect radio microphones, liturgical players, electronic organ, CD player, CD/DVD recorder-player, etc.
3 – REC OUT
Use this audio output for recordings. Whenever necessary it can be used as a normal AUX output. Important When the REC led is on, AUX 2 input (11-12) will be automatically disconnected to avoid loop on the audio signal.
4 – L & R (DELAY) OUT Audio outputs L & R (Right can have a delay compared to the Left) and in parallel, L & R balanced outputs. Important: All four outputs can be used at the same time with the same volume and tone controls.
