TX6000
6 Channel Mixer
Product Description
The TX6000 is a 6 channel audio mixer that operates from 240 VAC @ 50 FIz (or I l0 VAC @ 60 llzwith factory modification) a
24 WC via an extemal battery supply. The TX6000 is I standard rack unit high (a4mn) and has a standard rack width of 482mm.
For table mounting rubber feet are supplied but these can be removed if rack mounting is intended. Featuring six dual purpose inputs
consisting of XLR balanced mic inputs and dual RCA aux/line level inputs. Channel 6 has a high€r aux/line level input sensitivity to
enable it to accept a CD player or similar high level input sigrral.
Front Panel Controls
l. Dual ilicrophone/Line Gain Gontrols: The 6 dual mic/line input contols are marked Ch I thoireh Ctr 6 and
strould be adjusted to provide the required mix level for each individual channel. Start with the contols set to level g-and turn thl
controls slowly clockwise until the desired mix for eactr ctrannel is obtained.
Bass Tonal Control: Setting this contol in the cente "zero" position will give an overall flat bass respoirse to the output
of the amplifier. Adjusting the bass contol in a clockwise direction will provide up to +12 dB of bass boost @ 100 Hz. Adjusting
he bass c.uttol in a counter-clockwise directisr will provide up to -12 dB of bass cut @ 100 Hz.
Treble Tonal Control: Seting this contol in the centre "zero" position will give an overall flat teble response to the
output of the amplifio. Adjusting the treble contol in a clockwise direction will provide up to +9 dB of teble boost 6 l0 kHz.
Adjusting the teble control in a counter-clockwise directiqr will provide up -9 dB of teble cut at l0 kFIz.
U?:tq Output Control: This contol adjusts fte overall output level of the mixer depanding on the levels set for the
individual input mix channels as daailed above. Start wittr the contol level set to level 0 and slowly turn ttre contol clockwise
until the desired output level of the mixer is readred.
Headphone_ Output Socket A l/4- TRS stereo socket is provided for the connection of monitm headphones. The
otrtput level to the headphmes is a nominal 3.5 volts @ 600 ohms and is connected before the mast€r ouput levei controls so
adjusting the output level contols will not effect the headphone outprd level.
POWef SWitCh: This switch contols the switching of the AC power to the mixer. Rocking this switch upwards tr:rns grr AC
power to the mixer while rocking the switch downwards turns pow€r offto ttre mixer. When in the upward'dr" position, the red
neon in the body of the switch will glow.

7' LED Display VU Meter! Marked in decibel graduations from -21 dB to +3 dB, the light emitting diodes will indicate the
volume level at the output of the mixer. For normal operation the LED's glow green as they modulate with the output level of the
mixer. If the lights are consistently indicating red the mixer is being ovodriven, resulting in distortion in the quality of the audio
sigrral.
Rear Panel Connections
l. 3 Pin IEC AC Mains Power lnlet The operating voltage is 240 VAC @ 50 Hzor I l0 VAC @ 60tuz. The AC power
voltage is not externally user adjustable but is factory preset. The inlet is equippedwith an inbuilt AC fus; holder fitted with a 0.5
amp slow blow fuse plus one spare. Power consumptior is 15 VA. E Pleasc ensure thst the mains power cord is
disconnected before attempting to check or rcplace this fuse.
24 Volts DC Power Source Connection: 2.lmm DC power socket allows for the connection of an exrernal 24
VD.C battery for applications where PA systern operation is imperative. The centre terminal post or pin is for connection to the
positive (+) tenninal. The sleeve is for connection to the negative (-) terminal.
Spare SCrew Tgfminalsl These spare screw terrninals allow the connection of various optiural tone module accessories.
They are not connected to any point in the mixer from the factory and are spare.
!-ilp_Ogtput ude XLR style active balanced isolated output for connection to a power amplifier. provides a maximum of
l.sv RMS output. Suitable for driving power amplifiers or similar devices. Pin connectims are Pin I : Earth. pin 2 = Active
Positive (+). Pin 3 = Active Negative O.
IfpC OUtput 2 x RCA style phono output connector for line level output. Provides a maximurn of 700mV into loK Ohms,
ideal for a connection to most ttrydutd tape recorders. This outptd is sourced before the master gain contol and as sudr the tape
output level is not influenced by the operation of the master gain contol.
MiCfOphOne lnputsl Note: All inputs are universal line / microphone inputs Both connectors can not be utilised for
any one input channel. Six fernale XLR inputs accept 200 Ohm balanced or rmbalanced microphone inputs. Pin connections are
Pin I : Earth. Pin 2 : Active Positive (+). pin 3 : Active Negative O.
Line lnpUts: Note: All inputs are universal line / microphone inputs. Both connectors can not be utilised for any one
input channel. Six pairs of RCA style phono input connectors acc€,pt unbalanced line or auxiliry inputs for channels I through
6. Channel 6 accepts higha level inpus such as a CD player.
