Overview: Channel Modes and Network
The power amplifier shall provide two channels of amplification.
A rear-panel switch shall bridge the two channels for increased
power output through a single channel. The amplifier shall employ a
proprietary tracking Class D output circuit topology. The amplifier
shall be equipped with sensing and communication circuits to allow
comprehensive remote control and monitoring functions via a sepa-
rate 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 13000 watts.
Each amplifier channel separately shall deliver maximum continu-
ous output power as follows: 1200 watts into 16 ohms, 2350 watts
into 8 ohms; 4400 watts into 4 ohms; or 6500 watts into 2 ohms.
Maximum output voltage per channel shall be 195 Vrms; maximum
output current per channel shall be 58 Arms. In bridged mode, the
amplifier shall deliver maximum continuous output power as follows:
4700 watts into 16 ohms; 8800 watts into 8 ohms; or 13000 watts
into 4 ohms.
Default amplifier gain shall be 35 dB, with rear-panel adjustment
from 23 to 44 dB in 3 dB increments, selectable for each channel.
For bridged channels, the amplifier shall automatically compensate
-6 dB gain internally to maintain operation of all channels at selected
gain.
The amplifier shall exhibit the following performance parameters
with gain set at 35 dB and VPL (Voltage Peak Limiter) at 195 V:
Frequency response shall be 6.8 Hz to 34 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 limit-
ing characteristics.
Connectors, Controls, and Indicators
The following connectors and controls shall be on the REAR-PANEL
of the amplifier. 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. Seven DIP-switches shall be provided to select
the following: amplifier gain (23 dB to 44 dB in 3 dB increments);
option active; fan masked; and bridged mode selection. Eight ad-
ditional DIP-switches shall determine VPL values for each channel
(selectable in eight steps), and Hard or Soft limiting characteristic.
Two Ethercon-housed RJ45 connectors shall be provided for input
and output of the control/monitoring network signals. An LED adja-
cent 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 amplifier. Two level control potentiometers shall be detented
and provide attenuation from 0 dB to infinity in 21 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 flashing), 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-
fier 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 amplifier
shall be equipped with a PAL circuit to prevent excessive current
draw. The amplifier shall be cooled by two temperature-controlled,
variable-speed fans, with air flow from front-to-back. Adaptive fan
on/off function shall be dependent on presence of an output signal.
Physical
The amplifier 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 amplifier shall be approved for use as specified by CE, ANSI/UL,
ETL and the FCC. The amplifier shall be the Lab.gruppen FP 13000.
