RIGHT SIDE PANEL
Balanced outputs – The four main outputs are via transformer balanced XLR connectors. Left and
Right outputs are linked a Hirose 10pin multiway connector to facilitate rapid connection of outputs
and monitor returns. The line level is set on 600
Ω
at 0 dBu and +4 dBu for VU metered mixers. The
Hirose 10pin connector is wired as follows:
pin 1. +LEFT output
pin 5. RIGHT return
pin 2. –LEFT output
pin 6. N / C
pin 3. +RIGHT output
pin 7. LEFT return
pin 4. –RIGHT output
pin 8. N / C
pins 9., 10. GROUND
Unbalanced Post Fader outputs – A TA5M 5pin connector carries four unbalanced output signals
– at a level 3 dB lower than balanced outputs – to feed a recorder. The connector is wired as follows:
pin1-CH1 out pin2-CH2 out pin3-CH3 out pin4-CH4 out pin5-GROUND
Direct Channel Pre-Fader Outputs – via a TA5M connector, that is wired as follows:
pin1-CH1 out pin2-CH2 out pin3-CH3 out pin4-CH4 out pin5-GROUND
Line / mic level switches – The line level at XLR and Hirose connectors can be attenuated by
50 dB to provide the microphone level.
3.5 mm stereo monitor input jack
Video assist – A mono output formed by summing the Left, Right, Channel 3 and Channel 4 output
channels is also available on a TA3M connector. It is an unbalanced signal at 3 dB below the level of
unbalanced output. The connector is wired as follows:
pin1. GROUND
pin3. SIGNAL
Return 1 or 2 selector switch – In position RTN1 the 3.5 jack and Hirose returns are chosen for
monitor, switched to RTN2 the returns of RTN2 3.5 jack will be fitted by the monitoring circuits.
Power supply –The DC power stabiliser of TW mixer has built-in Poly-Fuse to protect the unit. If a
problem occurs that trips this fuse, it will reset after the power supply is disconnected for about 15
seconds. The mixer may be powered by 12 pieces internal AA size rechargeable batteries or an
external DC supply 12-24 Vdc. Fully charged batteries will typically power the mixer for 8 hours at
continuous use. The external XLR 4pin connector is wired as follows:
pin 1., 2. GROUND
pin 3. Battery Charge
pin 4. External 12-24 Vdc
