T
he Model 9T/Ti Amplifier offers unprecedented compatibility with
associated audio components. When connecting or disconnecting speaker
or interconnect cables, it is only necessary that the INPUT MUTE switch be
in the ON position if the Amplifier is already in operational mode.
Position INPUT SELECT switch to XLR if you are using XLR balanced
1
interconnects or to RCA if you are using RCA unbalanced interconnects
from your preamplifier or other source component.
Select one input — either BALANCED XLR INPUTS 1 or 2 or
2
UNBALANCED RCA INPUTS 1 or 2 — to match your interconnect cable
used. (Inputs 1 and 2 of either respective inputs are electrically
identical.)
A slight click may be heard when the XLR interconnect plugs are
3
installed correctly and latched. The latch (located on the input
connector and labeled PUSH) must be pressed to remove the XLR
interconnect cable.
Unscrew one set of the PARALLEL OUTPUTS connectors and install the
4
positive and negative loudspeaker cable spade terminals to the
respective Amplifier PARALLEL OUTPUTS. Red is normally positive;
black is normally negative. Since both PARALLEL OUTPUTS 1 and 2 are
electrically identical, the extra set can be used in loudspeaker bi-wire
configurations. ALWAYS USE THE SUPPLIED SPEAKER TERMINAL
HAND WRENCH WHEN CONNECTING OR DISCONNECTING
LOUDSPEAKER CABLES. DO NOT OVERTIGHTEN THESE TERMINALS.
!
Both positive and negative PARALLEL OUTPUTS are
WARNING:
electrically active with respect to chassis and/or system ground potential. It is
important that both of these outputs are electrically isolated from system
ground potential. This precludes the use of this Amplifier in certain loud-
speaker switching configurations (sometimes used in retail demonstrations)
and testing or servicing situations where either positive or negative outputs
can be connected to ground potentials. Failure to observe these precautions
may result in damage to the Amplifier and may void your warranty. Consult
the factory first if the Amplifier is to be used under these conditions.

Remote
A REMOTE connector (DIN 5-pin) is provided on the rear panel for
5
remotely switching the Amplifier between operational and standby
modes. The pin connections on this connector parallel the electrical
contacts of the FRONT PANEL STANDBY/POWER button and lamp. An
optional wired remote switch or infrared wireless remote sensor can be
plugged into the REMOTE connector to facilitate this function. Contact
your dealer or Jeff Rowland Design Group for further information and
availability of this feature.
