2. PAM5A Active Live Monitor

2.1 Quick Start - Active Speaker Cabinet

Make all initial connections, with the power switches Off for all equipment and main volumes are closed.

Connect one side of the signal cable at your audio mixer in to Output Left - Right (with Stereo - Jack or XLR) and
the other side of the cable in to the Line Input (Combo) of your active speaker cabinet. Start always with the LINE
switch sensitivity in +6dB positions.

Caution: The Line Input (Combo) and Link (XLR) are connected in Balanced or Unbalanced mode (Positive 2 /
Negative 3 / Ground 1).
The input with RCA connector, work in direct mode and by-pass the Volume control.

(1) Power Indicator

This LED lights up blue when the PAM5A active speakers are powered ON.

(2) Power Switch

This switch is used to turn the PAM5A active speakers ON or OFF.
Caution: Make sure your supply voltage is same to the value printed on the rear panel, before turn on the
switch, (230V - 50Hz # 115V - 60Hz).

(3) Mains Fuse

The fuse is a security device for mistake in the power supply, replace the fuse with the same type (230V ­2A # 115V - 4A).

Caution: Ask always at qualified personnel only.

(4) Power Cord

The power cord is a standard printed cable with ground makes for your security. Do not cut or replace the
connector, be sure that ground is always connected at voltage supply line.

Caution: Ask always at qualified personnel only.

(5) Main Volume

This control adjusts the proper signal present on the Combo Connector (Line Input).

The signal present on the RCA-Connector (Input) is out of the Volume Control.Caution:

(6) Out / Link

Balanced Output (XLR Male), can be used for linked at another PAM5A Active Speaker with the same signal
level of the first.

(7) Signal Input

Line Input on combined connector (XLR / Jack) for receive any type of signal Sources.
Balanced or unbalanced configuration is possible.

(8) Sensitivity Switch

Use this switch in LINE position at +6dB when you connect an Audio Mixer, use this switch in MIC position at

-45dB when you connect a Microphone.

(9) Direct Aux Input

Direct Aux Input, with RCA connector, the signal work without volume control at -10dB of sensitivity.

(10) Limiter Indicator

When the LED indicator, flashes in Red colour the limiter circuit is engaged, when the LED indicator switches
In fixed Red, the signal is excessive, adjust the Volume control or decrease the Mixer Output.

3. PAM5T Installation Speaker Cabinet

3.1 Quick Start Passive - Line 70.7V/100V connection

Make all initial connections, with the power switches Off for all equipment and main volumes are closed.

The 70.7V or 100V connection is possible only with power amplifier included the output transformer for same
voltage value 70.7V/100V.

Connect one side of the bi-wire cable at your 70.7V or 100V power amplifier and the other side at the Input of
PAM5T (push-button) or with a Mono Jack .

After this, select the desired power level of PAM5T, read the value in the 70.7V list from 60W (83 ohm) to 7.5W
(666 ohm) or in 100V list from 60W (166 ohm ) to 7.5W (1.33kohm).

Caution: Before switching ON the external power amplifier, verify the correct position of the Power Selections
(Off - 7.5W/15W/30W/60W ) and the correct position of slider selection (Passive - Line 70.7V/100V).

(2) Power Selections

With this rotary switch, it is possible to select the power level of the PAM5T from 7.5W minimum to 60W maxi­mum, for two different Constant Voltages 70.7V or 100V. In Off position the speaker system is disconnected
from the Line.

(3) Passive - Line Selector

The type of work for PAM5T is selectable by a slider selector.

When in PASSIVE position, the PAM5Ts work in passive configuration at 16 ohm.
When in LINE 70.7V / 100V position, the transformer inside will be engaged.
