Setting Up
Connect microphones to the Mic / Line / Instrument combo inputs (1) via XLR, ensuring that the +48V
button (3) is pressed in for any condenser microphones or D.I. boxes that require phantom power to
operate.
For line or instrument inputs (such as electric guitar), connect these via 6.3mm jack plug to the combo
inputs (1), ensuring that the IMPED button (2) is pressed in if it is a Hi-Z instrument.
(Hi-Z means high impedance, such as guitar pickups)
For stereo line level signals, such as CD or mp3 players, computer sound cards or electronic keyboards,
connect these via 6.3mm jack plug to the stereo inputs (4, 5) or if the input device is mono, just connect
to the L/MONO input (4)
A further stereo line input may be also connected to the 2TK INPUT (13) 2-track L+R RCA input for
monitoring back from a recording device or as an additional stereo playback source. This can be routed to
the MAIN OUT and/or PHONES outputs using the TO MAIN (15) and TO PHONES (17) buttons.
If headphones are to be used for monitoring the main output, connect these to the PHONES 6.3mm
stereo jack (19) and turn the PHONES control (18) down fully before listening to the headphones,
gradually turning this control up to the required level to avoid damage to hearing.
(note: this control is pre-master fader, which means that it can also be used as an independent output)
Connect the MAIN OUT L+R XLR outputs (20) to the amplifier, recording device or active speakers.
A further stereo line output can be connected from the 2TK OUTPUT (14) 2-track L+R RCA output, which
can be assigned from either the MAIN OUT or PHONES outputs using the FROM button (16)
Before connecting USB power, it is advised to turn all volume controls fully down to avoid any loud noises
through the connected speakers or recording equipment.
Insert the supplied USB lead to the USB port (12) on the rear panel and connect to either a host computer
or if not being used for digital audio, to a USB power supply with 5Vdc, 1A output.
The POWER LED on the top panel will light to confirm that power is on.
