DESCRIPTION
The SUB 05 speaker features an 15" woofer with an amplifier able to deliver 400W (RMS).
The subwoofer speaker is made using "BAND PASS" so high sound pressures can be
achieved in compact dimensions. Being made of poplar wood, weight is reduced and
handling is easier.
The SUB 05 diffuser has been designed to function in stereo and in mono modes.
This sub-woofer is ideal for sounding medium-sized rooms using a pair of diffusers from the
BASIC 100 or TWIN 128 connected in stereo mode
For installations requiring greater sound pressure, such as those in the open-air, two SUB
05 diffusers should be used together with two BASIC 200, OPERA LIVE 210, TWIN 228 or
OPERA LIVE 202 / OPERA LIVE 205 diffusers connected in mono mode.
COMMANDS AND FUNCTIONS
1)
VOLUME CONTROL
The knob regulates the speaker's volume. This control does not affect the
"BALANCED INPUT LINK" and "BALANCED X-OVER OUTPUT" levels.
2)
"PROT - LIM" INDICATOR
The "PROT - LIM" indicator lights up red :
-
when the amplifier is started (for a few seconds)
-
whenever an operating temperature is reached that is too high
-
during internal limiter operation, which prevents amplifier distortion and
protects the loudspeakers against overloads.
3)
"ON - READY" INDICATOR
The "ON - READY" indicator lights up green when the amplifier is correctly powered
and operating.
4)
"PHASE IN - PHASE OUT" SWITCH
This two-position switch permits rotating the audio signal reproduced by the sub-
woofer by 180°.
Such phase rotation facilitates the optimisation of the reproduction of low
frequencies even in the most difficult installation situations.
After completing installation, play a piece of music and operate the switch to achieve
the best sound reproduction.
5)
"BALANCED INPUT " INPUT CONNECTOR (CH1-CH2)
Balanced input suitable for connecting an audio source with signal output (0dBu).
6)
"BALANCED INPUT LINK" OUTPUT CONNECTOR (CH1-CH2)
The output is connected in parallel with the input (5) and can be used for sending the
input audio signal to another amplified diffuser, recorder or supplementary amplifier.
It can hold 3-pin XLR sockets.
7)
"BALANCED X-OVER OUTPUT" OUTPUT CONNECTOR (CH1-CH2)
Balanced output of the internal crossover. This signal is sent to an amplified speaker.
The crossover frequency between the subwoofer and the speaker connected to the
X-OVER output is 100Hz.
8)
POWER SWITCH
This switch turns the diffuser on and off.
9)
POWER CABLE SOCKET
Used for connecting the power cable supplied.
10)
FUSE CARRIER
Mains fuse housing.
11)
VOLTAGE CHANGE
For changing the power voltage of the speaker (230/115V).
This switch is preset and protected by manufactured
