Balanced outputs
– The main outputs are via transformer balanced XLR connectors and a Hirose 10pin
multiway connector is also fitted 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 9-10. GROUND
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
Unbalanced output
– A 5pin XLR connector carries an unbalanced stereo output signal – at a level 3 dB
lower than balanced outputs – to feed a recorder, DAT, etc. and monitor returns. The XLR 5pin connector is
wired as follows:
pin 1. GROUND
pin 2. LEFT output
pin 4. LEFT return
pin 3. RIGHT output
pin 5. RIGHT return
Channel Direct Outputs –
5 pin TA5F connector carries unbalanced direct outputs. Signal is prefader at a
level – 20dBu to feed a recorder and monitor returns with 3.5 jack. TA5F is wired,
pin 5. GROUND
pin 1. CH1 direct output pin 3. CH3 direct output
pin 2. CH2 direct output pin 4. CH4 direct output
Line / mic level switch
– 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
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 XLR7 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 diconnected 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
