crophone mixer. Its simple, compact design delivers superior perfor- mance and exceptional sound quality with low noise and a flat frequency response. Versatile in all types of applications, the SCM268 integrates transform- er-balanced XLR inputs, a switchable microphone/line level transform- er-balanced XLR output, phono jack inputs and output, phantom power, and an auxiliary input channel. It can function as a primary or add-on mix- er for sound reinforcement, recording, broadcast, or audio-visual presen- tation systems. With the supplied hardware, the mixer's half-rack chassis mounts se- curely in single or dual rackmount installations. For fixed installations, the SCM268 can be fastened on or below a shelf, counter, or tabletop. FEATURES • Four transformer-balanced microphone inputs • Transformer-balanced output-switchable mic/line level • Five -10 dB line-level inputs • Six-segment LED output level meter • Built-in 12-volt phantom power • Internal power transformer • Built-in low-cut filter on microphone inputs (below 80 Hz) FRONT PANEL Gain Controls (1-4). Adjusts gain for microphone level inputs and auxiliary level inputs 1-4. Auxiliary Channel Gain Control (AUX IN). Adjusts the auxiliary channel input gain. Output Meter. LED meter indicates peak output signal level. Master Gain Control (MASTER). Adjusts overall output level. Power Indicator (POWER). This LED illuminates when the unit is plugged in and receiving power. NOTE: The SCM268 does not have a power switch. To turn the unit off, unplug the power cord or use an external power strip with a switch. However, it can remain plugged in as it uses very little power when idle. REAR PANEL Power Connector.

for both microphone and auxiliary-level inputs of channels 1-4 (see Figure 1). For example, the channel 1 gain control is used for both the channel 1 microphone input (MIC LEVEL INPUT 1) and the channel 1 auxiliary level input (AUX LEVEL INPUT 1). The auxiliary gain control knob (AUX IN) af- fects only the auxiliary input (AUX IN). OUTPUT GAIN The master output gain control knob (MASTER) adjusts gain to both the XLR balanced output (MIC/LINE LEVEL) and the auxiliary level output (AUX LEVEL). OUTPUT LEVEL METER The six LEDs on the front panel labeled OUTPUT LEVEL METER illu- minate to reflect the peak level of the mixed output signal from the SCM268 (in reference to balanced line output) in dBu (0 dBu = 0.775 V). Use the master gain control (MASTER) to adjust peak levels, as indi- cated by the LEDs. The red LED illuminates when the output is 2 dB be- low clipping. PHANTOM POWER When the phantom power switch on the back panel is on (12V PHAN- TOM-ON), the SCM268 provides 12 V of phantom power to each XLR mi- crophone input. The switch is recessed to prevent accidental engagement. Most condenser microphones require phantom power. Use it when connecting these types of microphones to the SCM268. NOTE: Phantom power does not affect the operation of balanced dynamic microphones. With phantom power on, they can be connected to the SCM268 in combination with condenser microphones that do use it. OUTPUT LEVEL SWITCH The output level switch on the back panel (MIC/LINE OUT) sets the level of the balanced XLR output. When set to MIC, it reduces the output by about 50 dB. Set the switch so that the output level matches the input level of the device to which you are connecting the SCM268. The switch is recessed to prevent accidental engagement. NOTE: The output level switch does not affect the auxiliary output (AUX OUT) level.

tions possible with the SCM268. Note that nothing is connected to the channel 4 microphone input (MIC LEVEL INPUT 4). This is because channel 4 is being used for the consumer-level equipment connected to the channel 4 auxiliary level input (AUX LEVEL INPUT 4). Connecting both auxiliary level and microphone level inputs to a single channel is not recommended because the SCM268 would not be able to independently mix the two sources.

For dual-mount or fixed installations. • 12 bracket screws, 1/4 in. (6 mm). For securing the brackets to the chassis. • 4 rackmount screws, 1 in. (2.5 cm). For mounting the unit in a rack. • 4 plastic washers. For use with the supplied rackmount screws. • 4 wood screws, 1/2 in. (1.25 cm). For fixed installations. RACKMOUNT INSTALLATION The SCM268 can be mounted as a single unit or dual-mounted with ei- ther another SCM268 or another Shure half-rack unit such as the SCM262 or DFR11EQ. Attach the rackmount brackets using one of the following methods: Single unit (half-rack) installation: 1. Attach the short and long rackmount brackets to the SCM268 with eight (8) of the supplied bracket screws. Dual-mounted installation: 1. Connect the two units together side-by-side using two (2) straddle brackets. The brackets should straddle the recessed edges on on the top and bottom of each chassis. Fasten them using eight (8) bracket screws. NOTE: Be sure to use both straddle brackets-one on the top and one on the bottom. 2. Attach the short rackmount brackets to the outsides of the com- bined units with eight (8) of the bracket screws. 3. After attaching the brackets, mount the unit in an equipment rack using the supplied rackmount screws and plastic washers. STAND-ALONE INSTALLATION Adhere the four (4) supplied rubber feet to the bottom of the unit at each corner. This will keep it from sliding and protect the table surface. FIXED INSTALLATION To permanently affix the SCM262 above or below a table, shelf, or counter top, use the following steps: 1. Fasten the straddle brackets to the recessed edges of the chassis using four (4) bracket screws. Top mount: Fasten the straddle brackets to on the bottom of the unit Hanging mount: Fasten the straddle brackets to the top of the unit. 2.

tions, use the following steps: 1. Unplug the power cord. 2. Remove the knobs and retainer nuts from the front panel (See Figure 2). KNOB ASSEMBLY FIGURE 2 3. Remove the four screws at each corner of the back panel. 4. Remove the two screws at each bottom corner of the front panel 5. Slide the back panel and pc board out from the rear of the chas- sis. CAUTION: When reassembling the SCM268, DO NOT OVERTIGHTEN the knob retainer nuts. Use a minimal amount of force to secure the nut (0.6-0.8 N⋅m (5-7 in⋅lb)). Damage to the internal components will result if too much force is used. LOW-CUT FILTER To bypass the built-in low-cut filter for a given channel, remove the specified resistor and place a 10μF to 33μF capacitor in the specified pc board location (polarity does not matter). Refer to the following table: To select a particular corner frequency for the low cut filter, remove the R18, R28, R38, or R48 resistor for a given channel as specified above. Then, in the corresponding pc board location (X17, X27, X37, or X47), place a capacitor of the specified value (polarity does not matter). Refer to the following formula for selecting the correct capacitor value for the de- sired corner frequency. where: C = value of capacitor in μF F = corner frequency (-3 bB) for low-cut filter in Hz The following table lists the low-cut frequency corners for some of the most common capacitor values: PHANTOM POWER DISABLE To disable phantom power for a given microphone input, remove the specified resistor as listed in the following table: LINE PAD To insert a 50 dB line pad for a given microphone input, remove the specified resistor and short the solder points at the specified pc board lo- cations. Refer to the following table: HOT MIC PAD Some condenser mics have a high output. In order to avoid overdriv- ing the input stage, the user may need to set the input pot lower than de- sired. To fix this problem, the user can place an 11 dB pad into the input gain stage of a selected channel. 1. Twist together the leads from one side of a 15 kΩ resistor and a 0.1 μF capacitor: 2. Solder the free ends of the resistor-capacitor combination into the holes at the jumper position indicated by the following table and remove the corresponding surface mount resistor. WARNING!
