1. Before turning on, please connect the system properly as shown. The Techconnect
Amp is not designed to drive a 4Ω load (i.e. 2 speakers from each output), so we
recommend only using one pair of low-impedance speakers. The speaker cable
must be unshielded with a gauge of no less than 0.75mm. THE WARRANTY WILL
BE VOID IF YOU USE UNSUITABLE SHIELDED CABLE. THIS IS A LOW-IMPEDANCE
AMPLIFIER. DO NOT ATTEMPT TO CONNECT 100V LINE SPEAKERS (Normally
any speakers with "t" in the part code)
2. Set the master volume to minimum, set the input selector to the required input, then
turn the unit on and adjust to suit.
