Connection In Stereo Mode; Connection In Bridge Mode; Important - Master audio DL Serie Manual De Instrucciones

Load Capacity: The DL Series Two amplifiers have a sufficient current capacity to
admit very low loads (up to 2 ? ). It should be taken into account that many
loudspeakers using passive filters and whose nominal impedance is of 8 ? do in fact
present impedance much lower than the nominal one, at certain frequencies.
Therefore it is advisable to use 2 ? loads only when one is perfectly aware of the
impedance curve of the loudspeaker system to be connected.

6 - CONNECTION IN STEREO MODE

First make sure that the BRIDGE/STEREO mode
selector, located in the input section between the
two connection points is in the STEREO position.
There are two speaker output connectors. CH A for the left channel and CH B for the
right channel, both are fitted with Speakon type connectors, or Terminal connectors.
Each Speakon connector has 4 terminal points labeled as +1, -1, +2 and -2. Only use
the pins +1 for the Positive pole, and -1 for the Negative pole. Use a 1.5 Allen key to
firmly attach the cable (maximum section 4mm). In mobile applications this
connection may also be soldered to guarantee better contact.
The other way to connect the Speaker Output is by Terminal connectors. Use the
Red Terminal for the Positive Pole, and the Black Terminal for the Negative Pole.

7 - CONNECTION IN BRIDGE MODE

To use MONO mode place the above mentioned
BRIDGE/STEREO selector switch in BRIDGE mode.
The corresponding indicator located on the front panel
between the two volume controls will light up
(BRIDGE, red).
IMPORTANT: In this position the output power of both channels is directed to a
single output (mono). In this operational mode the connections are made as follows:
The + Pole of the speaker is connected to the Speakon Pin +1 of CH A, or the Red
Terminal of the CH A. The – Pole of the speaker is connected to the Speakon Pin +1
of CH B, or the Red Terminal of the CH B (see diagram on the back cover of this
manual). The power delivered by the amplifier will be the sum of both channels (at 4
? ), but the Load Impedance will be 8 ? . Permanent installations in Bridge Mode are
not recommended for impedance below 8 ? .
