Featurs - Macrom 42.15 Owner's Manual

• 3/2/1 CHANNEL OPERATION
The amplifier can be operated as a stereo or a as mono-bridged amplifier thus doubling the output
power independently from the input mode; the power can be subdivided as follows, according to
your needs:
a) 70/100 Watts for each one of the two channels
b) 70/100 Watts for two stereo channels, and 150/200 Watts mono
c) 150/200 Watts for one mono channel
• INPUT MODE SELECTOR
This switch allows the user to specify the input signal to the amplifier.
a) STEREO MODE
b) LEFT MODE (L - MONO)
c) LEFT + RIGHT MODE (L+R)
• END STAGE WITH DISCRETE COMPONENTS (TRANSISTORS)
• HIGH PERFORMANCES, LOW NOISE LEVEL, PASSIVE AND ACTIVE COMPONENTS
• NO CURRENT LIMITATIONS
The current limitation circuits incorporated in traditional amplifiers may cause untimely clipping
and a low transient response. The absence of such circuits assures a low T.I.M. effect, an
excellent transient response and a perfect sound quality.
• RCA INPUT SENSITIVITY
The new amp has a 500mVsensitivity for ideal coupling with MACROM sources and, however,
it is possible to regulate the sensitivity from 100mV to 2V to facilitate coupling with any other
source present on the market.
• REMOTE ON AND OFF
On switching the head unit on or off, the amplifier is automatically switched on or off.
• ON/OFF INDICATOR
• THREEFOLD PROTECTION
Your unit is provided with three different protection devices, as befits all high-end products.
SOFT START: the amp powers gradually in order to avoid damage to the speakers in case the
head unit is switched on with the volume control set to maximum.
OVERHEATING: in case of wrong installation the unit enters the protection mode before being
damaged. As soon as the temperature returns to normal values, the unit resumes normal
operation.
OUTPUT SHORT CIRCUIT: in case of a short circuit at the speaker outlets the unit enters the
protection mode in order to avoid serious damage to the end-stage transistors. Normal operation
is resumed on eliminating the short circuit.
• CAPACITIVE/INDUCTIVE POWER SUPPLY FILTER
This filter reduces radio frequency interferences (RFI) and cuts off system noises (i.e. the whine
of the alternator).
