4.-
MASTER
: control for regulating the general output volume for all inputs.
5.-
INPUT 1-4
: volume controls for INPUT 1-4.
6.-
PEAK
: LED indicator that lights up red when the input signal level is very high and there is distortion. If
the LED indicator lights up continually, lower the input signal level until it goes off or lights up
occasionally.
7.-
SIGNAL
: LED indicator that lights up green when a signal is detected in one of the inputs.
8.-
POWER
: LED indicator (blue) for amplifier power.
9.-
Amplifier on/off switch.
BACK PANEL
1.-
24 V DC power terminals. For the amplifier to work with external power.
2.-
OUTPUT
: speaker output. For connecting speakers in 4-8 Ω low impedance and 100/70 V high
impedance lines. Connect the speaker line between the COM terminal and the impedance or line with
desired voltage.
3.-
FM ANTENNA
: aerial input for digital FM tuner.
4.-
TEL. INPUT
: telephone input terminals. For connecting a telephone switchboard and to page from it
with priority over the other inputs. Make the connection between the + terminals (positive) and -
(negative) on the euroblock connector. Check the switchboard characteristics in order to adjust the
amplifier input level.
5.-
TEL. INPUT LEVEL
: volume control for the TEL. INPUT input. Turning the control wheel clockwise,
turns the volume up and in the other direction it turns it down.
6.-
Input for AC power cable connection.
7.-
Earth screw, to be used in the case of the mains not having one incorporated.
8.-
LINE OUT
: auxiliary line output. Output signal for recording, mixer, power amplifier, etc., 2 x RCA
connectors.
9.-
INPUT 4
: auxiliary input. Input for signal source, allows connection through 2 x RCA connectors from
audio sources.
10.-
INPUT 1-3
: microphone/line inputs, combo connectors (XLR and 6.3 mm jack).
11.-
LINE/PHANTOM 18 V/MIC
: input and 18 V phantom power sensitivity switches. These switches
have 3 positions:
LINE
: in this position, line level audio sources: CD players, etc. can be connected to the inputs.
PHANTOM 18 V
: in this position, electret condenser microphones that require 18 V phantom power can
be connected to the inputs.
MIC
: in this position, 30-600 Ω low impedance dynamic microphones can be connected to the inputs.
