ENGLISH STEREO PASSIVE CONTROLLER Forward heartful sensitivity. We believe that you, a devoted music lover will be fully pleased with our rich musical sound that is of a caliber never before experienced in your room. We are confident that the product will provide you with many years of satistying entertainment. Thank you for purchasing a Rotel high-end product. This Rotel component has been endowed with years of our dedicated work in audio technologies, the result of countless technical experiments and stringent listening tests during development. That we have devoted so much time in conducting these tests has come about for no other reason than the fact that we at Rotel simply love good music. In our pursuit of genuine musicality, Rotel has been very stubborn about circuit designs and uncommonly exacting in selection of parts so as not to depart in any way from the basic Rotel philosophy of balanced design and no-nonsense operation. The deciding factors behind the sound reproduced by this component were not determined by high-performance measuring instruments or computers but by human ears with NOTE The design philosophy of this product is different from that of conventional audio components. Because of this. several areas concerning how the product is used and how it is connected require special attention. Before you enjoy the rich musical sound provided by this product, please take some time to familiarize yourself with the contents of this manual to ensure that you will use it effectively and safely. Prior to Use For safe use of this component, please adhere to the following cautions: 1. Do not attempt to modify or otherwise alter this product. This component has been adjusted and inspected at our factory before being shipped. Attempts at alterations not only can cause problems but can also contribute to deterioration of its superior sound quality. 3. In the event that water or other foreign matter enters the unit... Water or other foreign matter entering the unit is a cause for breakdown. Please ensure that this does not occur. In the event a breakdown of this type does occur, disconnect the unit and consult the authorized Rotel dealer where you purchased it. 4. The owner's manual Keep this manual in a safe place with your warranty copy. Let it be available readily to you whenever you need to consult it. 2. Choose a proper location. Place the unit horizontally in a location that is free of vibrations, humidity, dust, and away from direct sunlight. Connecting Components This unit is a passive controller, equipped with 5 sets of high level input terminals and 2 sets of output terminals. It is a device that is designed for adjusting output levels and selecting input sources; no amplification or equalization of any kind is incorporated. The input terminals can accommodate components such as CD players, DATs, tape decks and tuners, except turntables which do require amplification. As for the two output terminals, RECORD OUT is for output to tape decks while MAIN OUT is for output to the RHB-10 or other power amplifier. Use only highest grade interconnect cables when making connections. Left-channel terminals are aligned along the upper row while right-channel terminals occupy the lower row; be sure that you connect the LEFT OUT and RIGHT OUT of the output devices to this unit correctly.

Operating the knob will alter the volume that is reproduced through the power ampplifier. Turn the knob to the right (clockwise) to raise the volume, or to the left (counter-clockwise) to lower it. The front piece of the knob toward you operates the right channel while the larger back piece is for the left channel. Though both pieces of this cocentric knob can be operated simultaneously, using them separately lets you adjust the balance between the two channels. OUT terminal from among input terminals 1 - 4 on the rear panel. (Input terminal 5 is not affected.) Input terminals 1 - 4 are used when signals from a source connected to one of these terminals are to be recorded onto a tape deck. Turn the switch to OFF when not recording. (3) Input Selector The Input Selector switch is used to select one of the 5 input terminals on the rear panel for output through the MAIN OUT terminal. Use this switch when you want to listen to signals from a source connected to one of these five terminals. (2) REC OUT Selector The REC OUT Selector switch is used to select a REC RITE Figure 2 Operations Check to ensure all components including this one are properly connected. Listening 1. The signals to be output through the MAIN OUT terminal to the power amplifier are selected using the Input Selector. Turn the attenuator all the way to the left to minimum. 2. Turn on the power of the power amplifier and start up play on the selected source. 3. Turn the attenuator toward the right until you reach the desired listening volume. Recording 1. Use the REC OUT Selector to select the source device you wish to record. 2. Start play on the selected source device and start the recording function on the tape deck. NOTE: The attenuator will not work for recording since the signals will not be passing through it. Monitoring the sound during recording, is possible, but we discourage this as it can adversely affect the highest-quality sound guaranteed by this component. NOTE 1: To enjoy the highest possible sound quality, be sure that the REC OUT Selector is set to OFF when just listening. NOTE 2: In the event that noise occurs, connect a wire to the ground terminal on the rear panel of this unit, and connect the other end to the ground terminal on the applicable source device or any other point on its chassis where noise can be brought down to a minimum. IMPORTANT When connecting a wire to another unit as described in NOTE 2 above, absolutely avoid touching the wire onto any areas related to the power source such as auxiliary AC outlets or inserting the wire inside the chassis. Concerning "Aging" and Handling of the Attenuator and Selectors Though this unit is completely passive system without a power supply section, it will also require "aging' or burning in" as with other high-end components. This "aging' process will stabilize the functioning and characteristics of the parts and circuits so that they deliver the highest quality sound possible out of this unit. Once all connections have been completed and the system is fully assembled, "aging' should be done in conjunction with the other components. "Aging time is normally about 100 hours. Since this component is equipped with the highest grade attenuator, even extremely slight oxidation inside the unit or loss of uniformity among electrical connections can cause degradation in the sound quality. On days you do not use the system, we recommend that you simply move the attenuator and selector switches while leaving the power to the system off, as even this operation will help to prevent deterioration over the years. IMPORTANT It is not necessary to "burnin" this unit by leaving it turned on through power amplifier for 100 hours continuously. Instead, let the unit age for a few hours a day over several days while you enjoy normal listening. During the aging period, it is important that you are within eye's reach of the system; when going out or sleep, for instance, stop the "aging" for the time and turn off the power to the entire system.
