Macrom 44.07 Stereo Amplifier User Manual


 
MACROM INGLESE 44.05/07 14 OTTOBRE 1992 8
FEATURES
4/3/2 CHANNEL OPERATION
The power of the 44.05/44.07 can be subdivided as follows:
a) 40/65 W RMS for each of the four output channels
b) 40/65 W RMS on two stereo channels and 110/150 W RMS mono
c) 100/150 W RMS on two stereo channels
NO AMPERAGE LIMITATIONS
The amperage limitation circuits incorporated in traditional amplifiers may cause untimely
clipping and a low transient response. The absence of such circuits ensures a low T.I.M. effect,
an excellent transient response and a perfect sound quality.
INPUT MODE SELECTOR
This selector allows the user to choose between 2 or 4 input signals to the amplifier.
OUTPUT MODE SELECTOR
This selector allows the user to specify the number and the configuration of the outputs.
BY-PASS OUTPUT
In the "2 CH INPUT" configuration a preamplified BY-PASS output with unitary gain can be used.
ADJUSTMENT OF INDEPENDENT CROSSOVER FREQUENCIES
This control allows for independent and continuous adjustment of the Low Pass and High Pass
crossover frequencies from 50 to 160 Hz adding great versatility to your unit.
REMOTE ON/OFF
On switching the head unit on or off, the amplifier is automatically switched on or off.
RCA INPUT SENSITIVITY
The sensitivity adjustment of this new amplifier is positioned at 500 mV for optimum coupling with
other MACROM sources. However, the continuous adjustment from 100 mV to 2 V is possible
for easy coupling of other sources available on the market.
CHECK CONTROL INDICATOR
This LED Shows the current state of the amplifier.
WHITE The unit is off.
GREEN The unit works perfectly well.
RED The unit is in the protection mode, verify connections.
TRIPLE 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.
FINAL STAGE WITH DISCREET COMPONENTS (TRANSISTORS)
