The Model 2 amplifier offers unprecedented compatibility with associated audio components. When connecting or disconnecting speaker or interconnect cables, it is only necessary that the FRONT PANEL STANDBY/ POWER button be pressed to switch the amplifier to standby mode. The button will not be illuminated in this mode.

1When installing the interconnect cables, a slight click may be heard when the XLR interconnect plugs are installed correctly and latched. The latch (located on the input connector and labeled PUSH) must be pressed to remove the XLR interconnect cable.

2When using RCA unbalanced interconnects from your preamplifier or other source component, install the supplied XLR/RCA adapters into both XLR input connectors. The Amplifier will still operate in the fully balanced (Differential Mode™) configuration.

3Unscrew RIGHT CHANNEL OUTPUT and LEFT CHANNEL OUTPUT connectors and install the positive and negative loudspeaker cable spade terminals to the respective Amplifier OUTPUT. Red is normally positive; black is normally negative. ALWAYS USE THE SUPPLIED SPEAKER TERMINAL HAND WRENCH WHEN CONNECTING OR DISCONNECTING LOUDSPEAKER CABLES. DO NOT OVERTIGHTEN THESE TERMINALS.

!WARNING: Both positive and negative OUTPUTS of both channels are 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 loudspeaker 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

4A REMOTE connector (DIN 5-pin) is provided on the rear panel for 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.
