Overview: Channel Modes and Network
The power amplier shall provide two channels of amplication. A
rear-panel switch shall bridge the two channels for increased power
output through a single channel. The amplier shall employ a pro-
prietary tracking Class D output circuit topology. The amplier shall
be equipped with sensing and communication circuits to allow com-
prehensive remote control and monitoring functions via a separate
network bridge. The proprietary control and monitoring network
shall use Cat-5 cable for interconnection, and shall allow control and
monitoring directly from the network bridge’s front-panel or, via the
bridge, from an external PC running proprietary software.
Power Output and Performance
Maximum total output of both channels shall be 14000 watts. Each
amplier channel separately shall deliver maximum continuous out-
put power as follows: 1200 watts into 16 ohms, 2350 watts into 8
ohms; 4400 watts into 4 ohms; or 7000 watts into 2 ohms. Maxi-
mum output voltage per channel shall be 195 Vrms; maximum out-
put current per channel shall be 85 A peak. In bridged mode, the
amplier shall deliver maximum continuous output power as follows:
4700 watts into 16 ohms; 8800 watts into 8 ohms; or 14000 watts
into 4 ohms.
Default amplier gain shall be 38 dB, with rear-panel adjustment from
23 to 44 dB in 3 dB increments. For bridged channels, the amplier
shall automatically compensate - 6 dB gain internally to maintain op-
eration of all channels at selected gain.
The amplier shall exhibit the following performance parameters
with gain set at 35 dB and VPL (Voltage Peak Limiter) at 195 V: Fre-
quency response shall be 2 Hz to 34.2 kHz, +0/-3 dB at 1 watt into
an 8 ohm load; channel separation shall be greater than 70 dB; and
signal-to-noise ratio shall be greater than 112 dBA. THD at 1 watt, 20
Hz – 20 kHz, shall be less than 0.1%; THD at 1 kHz shall be no more
than 0.05% at 1 dB below clipping.
A VPL shall limit peak output as determined by rear-panel switches.
In discrete two channel mode, peak voltage shall be selectable in
eights steps across a range of 195 V to 54 V. In bridged mode, peak
voltage shall be selectable in eight steps from 390 V to 108 V. The
voltage limiter mode shall be selectable for either hard or soft limiting
characteristics.
Connectors, Controls, and Indicators
The following connectors and controls shall be on the rear panel of
the amplier. The two signal inputs shall be electronically balanced
on XLR-F connectors, and each input shall have a parallel LINK out-
put on an XLR-M connector. The Speaker Output connectors shall be
binding posts or Neutrik Speakon. Seven DIP-switches shall be pro-
vided to select the following: amplier gain (23 dB to 44 dB in 3 dB
increments); option active; fan masked; and bridged mode selection.
Eight additional DIP-switches shall determine VPL values for each
channel (selectable in eight steps), and Hard or Soft limiting char-
acteristic. Two Ethercon-housed RJ45 connectors shall be provided
for input and output of the control/monitoring network signals. An
LED adjacent to the RJ45 connectors shall indicate active or inactive
status of the network.
The following indicators and controls shall be on the front panel of
the amplier. Two level control potentiometers shall be detented
and provide attenuation from 0 dB to innity in 31 steps. Individual
switches shall be provided for power on/off and remote power on/off
enabling. Front-panel LED indicators shall be provided to show status
of power on/off (green), network connection (blue), and PAL (Power
Average Limiter) (red). Additional LED indicators shall be provided
to show the status of the following for each channel: signal present
and high-impedance warning (green/red), signal present from -20 dB
to -4 dB (4x green), VPL clipping (red), CPL (Current Peak Limiter)
active (orange), VHF (Very High Frequency) warning (yellow), high
temperature warning (yellow ashing), and high temperature fault
with output muted (yellow constant), and Mute (red).
Power Supply, Protection, and Cooling
The power supply shall be a regulated switch mode type. The ampli-
er shall operate from AC line sources of either 230 V nominal or 115
V nominal, with operating ranges of 130 – 265 V and 65 – 135 V at
line frequencies of 50 Hz or 60 Hz. Minimum power-up voltages are
171 V (230 V nominal) and 85 V (115 V nominal). A soft start circuit
shall limit current inrush at power-up to 5 A. The amplier shall be
equipped with a PAL circuit to prevent excessive current draw. The
amplier shall be cooled by two temperature-controlled, variable-
speed fans, with air ow from front-to-back. Adaptive fan on/off
function shall be dependent on presence of an output signal.
Physical
The amplier shall be 483 mm (19 in.) wide, 88 mm (3.5 in / 2 U) high,
and 396 mm (15.6 in.) deep. The weight shall be 12 kg (26.4 lbs). The
cabinet shall be black painted steel with a black painted steel and
aluminum front-panel.
The amplier shall be approved for use as specied by CE, ANSI/UL,
ETL and the FCC. The amplier shall be the Lab.gruppen FP 14000.
