5.Arrows on potentiometers denote clockwise rotation.

6. Wire color designations with asterisks refer to stranded No. 20 AWG wiring, and those in parentheses refer to integral component leads. All other wires are stranded No. 24 AWG.

7.P. C. board terminals and wire destinations are shown as board number-pin letter.

8.First digit of three-digit component references (for example, R101) denotes number of printed circuit board upon which part is mounted. One and two-digit component references denote chassis-mounted parts.

9.AC and DC voltages given in Tables 2A, 2B and 2C are measured with a 2.2 megohm or greater AC volt- meter and a 10 megohm or greater DC voltmeter. All switches set as shown in schematic diagram. AC line

=120 V, 60 Hz. Input 3 control set to 5, Input 1 and 2 controls set to zero, and Response Rate control set to 3. Input signal 1 kHz applied to Input 3, level ad- justed for 10 dB compression (signal at Pin A, board 3 equal to -30 dBV or 32 mV). Output control ad- justed for + 4 dBm (+ 1.8 dBV or 1.23 V) line output into a 600-ohm load.
