MACROM INGLESE 42.15 - 42.17 17 FEBBRAIO 199310
CONNECTIONS
CONNECTIONS ( Fig. 3 Pag. 4 )
1 Positive output terminal for left speaker or positive output terminal if used in MONO
2 Negative output terminal for left speaker
3 Positive output terminal for right speaker
4 Negative output terminal for right speaker or negitive output terminal if used in MONO
5 RCA-type input connector, left channel or mono
6 RCA-type input connector, right channel
7 20/25 Ampere fuse
8 Feed terminal + 12 V to the battery
Connect this terminal directly to a positive (+) terminal of the battery by means of a lead
responding to the amplifiers power requirements.
9 Terminal for the connection of the negative ground lead
10 Terminal for REMOTE switch-on
1. Battery lead . Connect this terminal (+BAT)➇ directly to the battery cable of the car, by using
an adequately sectioned cable (yelow).
Do not connect this lead to circuits existing within the electric system of the car. In order to avoid
damage to the car it is imperative that this lead be fitted with a fuse (not supplied) as near as
possible to the car‘s battery. This connection is to be carried out last.
2. REMOTE switch-on lead (blue). Connect this lead to the remote switch-on lead or connect the
control lead of the power antenna coming from the head unit to the REMOTE terminal ➉.
NOTE: If this lead is not connected, the amplifier will not be switched on when the head unit is
switched on. If your head unit is not fitted with an outlet for a power antenna, a quick-break lever
switch (SPST) should be installed between the power source (+12 V) and the remote switch-
on lead and connected to the REMOTE ➉ terminal so as to allow the manual activation of the
amplifier.
3. Ground lead . Secure the ground lead to a clean spot on the car chassis and to the GND terminal
➈. Make sure that there is electric continuity between this spot and the negative terminal of the
battery. Use the shortest possible ground cable and if more than one amp should be used,
connect the relative ground to one sole point.
4. FUSE. In case of fuse replacement be sure to use fuses of the same amperage.
The use of fuses with the wrong amperage may seriously damage the components of the unit.
5. SPEAKER OUTLET TERMINALS. Be sure to keep the right polarity and phase in connecting
the speakers. This includes the control of the right polarity, positive (+) and negative (-). NOTE:
Avoid any contact between stripped wires and the ground lead.
6. RCA INPUT CONNECTORS. The line output leads of your head unit should be connected to
the RCA input connectors, respectively RCA right ≈ and RCA left ➄ , by means of a RCA
extension cable ( e.g. 90.05-90.10-90.25-90.50 by MACROM). Be sure to respect the right
channel designation: left (white) and right (red).
