Introduction The BUC 102 is an audio converter capable of balanced-tounbalanced or unbalanced-to-balanced signal conversions.
Installation and Operation, cont’d Installation and Operation Mounting the BUC 102 The BUC 102 can be set on a table, mounted on a rack shelf, mounted under a desk or table, or installed on a projector mount. Tabletop use The BUC 102 comes with four, self-adhesive rubber feet (not attached). For a tabletop installation: 1. Attach the rubber feet to the underside of the BUC 102 near the corners of the unit. 2. Place the BUC 102 unit in the desired location.
Rack installation The BUC 102 can be rack mounted using either the RSF 123 VersaTools 19" 1U rack shelf (Extron part #60-190-20), the RSB 123 basic VersaTools rack shelf (Extron part #60-604-20), the RSU 129 standard universal 1U rack shelf (Extron part #60-190-01), or the RSB 129 1U basic rack shelf (Extron part #60-604-01). Figure 1 shows the VersaTools rack shelf, and Figure 2 shows a standard rack shelf.
Installation and Operation, cont’d Back of the rack installation The BUC 102 can be conveniently mounted on the rear of a rack by using the MBB 100 Extron back of the rack mounting kit (Extron part #70-367-01). The back of the rack mounting kit allows the BUC 102 to be vertically positioned. 1. Attach the back of the rack mounting brackets, one bracket at a time (see note below), to the sides of the BUC using the two cover screws on each side of the BUC.
Furniture/Projector mounting Use the MBU 123 optional mounting kit (furniture, part #70-212-01, or the PMK 100 projector pole mount kit, part #70-217-01) to mount the BUC 102, as follows. Furniture mounting 1. Remove the rubber feet if they were previously installed. 2. Attach the mounting bracket to the BUC 102, as shown here. 3. a. Remove the two machine screws from one side of the unit. Save these screws for future use. b.

Be careful to observe the correct polarity.
Installation and Operation, cont’d The blue connector does not have the extended tail or the included tie-wrap. Do not tin the power supply leads before installing in the direct insertion connector. Tinned wires are not as secure in the connectors and could be pulled out. After making any adjustments to the BUC 102, either via the front panel controls, SIS commands, or the Extron Audio Products Control Program, wait at least 10 seconds after making those changes before disconnecting power to the BUC 102.
R Unbalanced Input 5 R L Tip Sleeve Tip Ring Sleeve (s) Tip Ring L Tip Sleeve Balanced Input Bal/Unbal output DIP switch — In general, match the DIP switch setting to the output wiring to achieve unity gain. The following table shows the gain settings associated with the DIP switch options and the corresponding output wiring configuration when the front panel gain controls are adjusted to the unity gain position. See “Front Panel Features” in this chapter.

The gain is adjusted by rotating the screw and the adjustment range is from mute (fully counterclockwise) to +20 dB (fully clockwise). See 5 under “Rear Panel Features and Cabling” in this chapter. See note below.
