120V
TX6n
The YAMAHA TX6n shall be a two-channel power amplifier. This amplifier shall draw 1800W or less at 1/8 rated power into 2 ohm loads. The power
amplifier shall be capable of operation from a 120 V, 60 Hz line. Dual power supply transformers are employed. The amplifier shall meet the following
performance criteria. Power output with both channels driven shall be a minimum of 2750W per channel with a 2 ohm load, 3000W per channel with a 4
ohm load, 1800W with an 8 ohm load, 6000 W mono bridged into an 8 ohm load, and 5500 W mono bridged into a 4 ohm load. Burst peak output with both
channels driven shall be a minimum of 4100W per channel with a 2 ohm load. Total harmonic distortion (THD+N) shall be less than 0.2% at 10Hz-20kHz,
half power. Intermodulation distortion (IMD) shall be less than 0.25% using the SMPTE standard of 60 Hz and 7kHz in a 4:1 ratio respectively at half
power. Frequency response shall be from 20Hz to 20kHz (Max +0.5dB, TYP +0 dB, Min -0.5 dB) at 8 ohms, Po=1W. Residual noise at 20Hz-20kHz shall be
less than -65dBu. Input shall be electronically balanced, with a minimum impedance of 20k ohm balanced and 10k ohm unbalanced. The voltage gain shall
be configurable in 0.1dB steps between 19.8dB to 43.8dB. Maximum input voltage shall be 24dBu. The unweighted signal to noise ratio over the range of
20Hz-20kHz shall exceed 108dB, referenced to full output. Built-in protection circuitry shall monitor voltage and current levels to minimize potential damage
from overloads, and disable output during shorts, DC offset, or excessive operating temperatures exceeding 100° C. The relay shall also delay amplifier
connection to the load during turn-on for nine seconds. In-rush current limiting shall minimize turn-on current surges when multiple units are powered-up
remotely to prevent AC breaker overload. The amplifier shall employ forced-air cooling with dual temperature-controlled fans, variable in speed for
minimum acoustic noise. Air flow shall be from front to rear. The front panel shall have a recessed AC power switch, two MUTE buttons, four Function
buttons, a HOME button, an ENTER button, two encoders and LED indicators. The LED indicators shall indicate IDENTIFY, NETWORK, PROTECTION,
BRIDGE, PARALLEL, POWER and STANDBY conditions. Front panel indicators shall include an LCD screen to control the amplifier's setup and
operation. Rear panel input connectors shall be a 3-pin XLR connector for each channel and available input connectors via the Mini-YGDAI card. The XLR
input shall be wired with pin 2 hot. Rear panel output connectors shall be 5-way binding posts, SPEAKON connectors, XLR Thru outputs and available
connectors via the Mini-YGDAI card. The RJ45 Data Port connector shall allow remote control and monitoring via Ethernet connection to the Amp Editor
application network. The Fault Output connector shall provide relay contacts rated for a load of 30V DC, 1A to indicate abnormality in the amplifier operation.
The amplifier shall include an onboard 32-bit DSP with 24-bit A/D and D/A conversions. The amplifier shall employ patented EEEngine technology including
MOSFET based independent high speed current and voltage buffers without delay circuits to improve slew rate. Efficiency @ 1/8 duty cycle shall be 50%.
Isolation components shall be provided and output devices shall be mounted by individual screws to minimize sonic degradation caused by vibration. The
power cable shall use a 30A twist lock connector, NEMA L5-30P. The amplifier shall conform to the latest EU RoHS hazardous substances and WEEE
directives. The amplifier shall be certified to meet Underwriters Laboratories Inc.'s safety requirement UL60065 and Intertek ETL SEMKO standard
EM60065:2002 at 2 ohms. It shall use only two standard rack-spaces and its dimensions shall be 480mm W x 461mm D x 88mm H (18-7/8” x 18-1/8” x
3-7/16”). Weight shall be 16 kg (35.3lbs). The amplifier shall be YAMAHA TX6n.
