Mode Switch
5:
This mode is automatically stored by the microprocessor. It is also adjustable by
remote control. (Ti4250 – Bridge/Stereo only – single yellow LED indicates
Bridge mode)
6: Audio Input XLR Connections
The amplifier is designed to operate with fully balanced equipment and ground
loops or loss of performance may be experienced if connected to unbalanced
sources. If it is unavoidable however, the following wiring should be used. The
cable should still be twin core plus screen.
PIN1: Screen - connected to the chassis of the unbalanced equipment - or left
disconnected at the unbalanced end.
PIN2: Signal Hot
PIN3: Signal Cold
NOTE: This amplifier is wired to the latest industry recommendations. PIN1 is
connected directly to the chassis/mains earth. If ground loops (mains hum) are
encountered remove the screen connection from the other end of the cable and
leave it open circuit. If problems persist, consult your dealer/supplier.
DO NOT TAMPER WITH OR ALTER ANY GROUND (EARTH) CONNECTIONS INSIDE
For bridged operation input should be made to channel A only and the rear panel
mode switch pressed to select bridged mode.
Amplifier Operator's Manual
This momentary action switch
cycles through the three amplifier
modes, illuminating the
accompanying mode LED as
appropriate:
Mono Mode – Yellow LED
Stereo Mode – Green LED
Bridge Mode – Red LED (and front
panel LED)
The inputs are made via 3-pin XLR connectors
along with "Phoenix" connectors (wired directly
in parallel), which are electronically balanced
and should be connected via a high grade twin
core screened cable, as follows:
PIN1: Screen (see note on next page)
PIN2: Hot (signal +)
PIN3: Cold (signal -)
