Input/Output Connections
LINE
– each line input corresponds to the mix channel on the main CONTROL CONSOLE. This TRS ¼"
TRS input connection will accept either balanced or unbalanced signals from line level devices such as tape
decks, CD and DVD players, computer sound cards, MP3 players, preamplifieed musical instruments, and
similar devices.
MIC
– each mic input corresponds to the mix channel on the main CONTROL CONSOLE. This XLR input
connection accepts balanced mic level signals. Note that for each input, only the MIC or LINE connection
should be used. NOT BOTH.
EFFECTS LOOP SEND
– provides a line level mix output to an external effects processor.
EFFECTS LOOP RETURN
– allows processed signal to be inserted into the mix from an external effects
processor.
TAPE IN
– allows playback from external audio recorder through the main mix. The relative level of this
recorder is set by the TAPE/MP3 adjustment, under the EFECT section of the CONTROL CONSOLE.
REC OUT
– provides line level output to an external audio recorder. This output is affected by the settings
under each channel of the mixing console, but not by the settings in the MAIN MIX section.
Rear Panel
POWER
– turns main power ON or OFF. Depressing
the "–" side of the switch turns the unit ON, the "O"
turns the unit OFF.
The IEC type power accepts standard equipment
power cords. Only grounded, three-conductor cords
of at least 16AWG wire size should be used.
The fuse holder is located in the base of this input
socket. In the event that fuse replacement is
needed, replace only with the same type, 5mm x
20mm, 5A fast blow fuse,.
OUTPUT –
connections accept standard 2-
conductor ¼" speaker cables. This amplifier is
capable of driving speaker loads as low as 4ohms
per channel. Loads lower than 4ohm will cause
permanent damage to the amplifier.
SPEAKER CONNECTION
Each speaker is equipped with two ¼" and a single twist lock (compatible with Speakon) input connection.
These inputs are all tied together in parallel and are designed to facilitate easy connection of a second set
of speakers, or a subwoofer.
It is important to note that if speakers are to be used in addition to the pair provided, they MUST be 8ohm
or higher. Additionally, no more than one additional speaker (per channel) may be added. Connecting a
second set of speakers lower than 8ohm, or having more than two pairs of speakers connected to the
amplifier at one time may cause permanent damage to the amplifier.
To obtain optimum performance from this unit, it is important to select adequate speaker wire. For
distances up to 15' per speaker, at least 18 AWG wire should be used. Distances greater, but less than 50'
should use 16AWG. Distances beyond 50' should use 14AWG speaker cable.
