Detailed instructions for use are in the User's Guide.
[. . . ] If the Amplifiers do not operate correctly, please notify your dealer immediately. If the Amplifiers are returned to your dealer or Jeff Rowland Design Group, the original packing materials must be used for shipment. Neither Jeff Rowland Design Group nor the shipper can be held responsible for damages incurred during transit if the original factory packing is not used. All factory returns require that a Return Authorization number be issued by Jeff Rowland Design Group prior to shipment.
Contents Ensure that all of the auxiliary components listed below are enclosed
within the accessory box. [. . . ] As a general rule, most installations allow each Amplifier chassis to be rigidly coupled to the supporting structure via the spiked coupling interface supports. In carpeted installations, these supports provide excellent coupling from the Amplifier chassis to the rigid supporting structure below. In installations where the integrity of the supporting structure is poor, the Amplifier chassis can be loosely coupled to the supporting structure via the compliant isolation interface supports. This will help attenuate the transfer of spurious energy from the supporting structure into the Amplifier chassis. Note: Another installation option, when incorporating the Battery Power Source, utilizes its chassis as a stable, high mass structural support for the Amplifier chassis. In this configuration, the Battery Power Source chassis is rigidly coupled to the supporting structure via the spiked coupling interface supports and the Amplifier is placed directly above the Battery Power Source and isolated via the compliant isolation interface supports. If desired, a coin may be placed directly under the point of the spiked coupling support to prevent damage to various surfaces (i. e. hardwood floors).
Rear Panel Power Connections
Important: Please strictly follow the steps in order as outlined below
before operating your Model 6 Amplifiers.
1
Verify that the supplied connector jumpers and covers are installed correctly to the JUMPER/BPS-6 CONNECTOR on each Amplifier. These connector jumpers can serve as an interlock to prevent unauthorized operation of the Amplifiers when not in place. When using the companion BPS-6 (Battery Power Source), these connector jumpers must be removed and the BPS-6 DC power cables must be installed in their place. Verify that the VOLTS 50/60 Hz INPUT identified on each rear panel corresponds to the AC mains voltage of your service area. Install the AC power cable between the Amplifier and an active AC mains outlet.

Signal Connections The Model 6 Amplifiers offer unprecedented compatibility with associated audio components. When connecting or disconnecting speaker or interconnect cables, it is only necessary that the FRONT PANEL STANDBY/POWER buttons be pressed to switch the Amplifiers to standby mode. The button will not be illuminated in this mode.
1 Remote 4
When 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. When using RCA unbalanced interconnects from your preamplifier or other source component, install the supplied XLR/RCA adapters into the XLR input connector on each Amplifier. The Amplifiers will still operate in the fully balanced (Differential ModeTM) configuration. Unscrew the positive and negative OUTPUT connectors and install the positive and negative loudspeaker cable spade terminals respectively to each Amplifier OUTPUT. ALWAYS USE THE SUPPLIED SPEAKER TERMINAL HAND WRENCH WHEN CONNECTING OR DISCONNECTING LOUDSPEAKER CABLES. DO NOT OVERTIGHTEN THESE TERMINALS.
A REMOTE connector (DIN 5-pin) is provided on the rear panel of each Amplifier 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. [. . . ] This condition requires that the driving source component (preamplifier) is equipped with balanced outputs and sufficient output current to properly drive the inputs of the Model 6 Amplifiers when the LOW INPUT IMPEDANCE option is selected. Therefore, most fault conditions which may occur during use will be indicated by the Model 6 reverting to a standby condition. JRDG = Jeff Rowland Design Group, Inc.
