NAD 114

GB
patch cord from processor�s outputs to the TAPE 1 IN jacks. The tape connections may be used with recorders of all types: cassette, micro-cassette, open-reel, digital, etc. To make recordings, connect a stereo patch cord from the TAPE 1 OUT jacks of the 114 to the recorder�s LINE IN jacks (not its microphone inputs). To play back tapes, connect a stereo patch cord from the recorder�s LINE OUT jacks to the TAPE 1 IN jacks of the 114. (See Figure 2) Insertion of a plug into the PHONES socket automatically mutes the signal at the PREAMP OUTPUT jacks, silencing the loudspeakers. In order to resume listening to loudspeakers you must unplug the headphones from the PHONES socket.

3. BASS.
The Bass control adjusts the relative level of the low frequencies in the sound. The electrical response of the preamplifier is flattest when the control is set in the detent at the 12 o�clock position. Rotation of the knob to the right (clockwise) increases the level of low-frequency sounds, and rotation counter-clockwise decreases their level. Adjust the Bass control to achieve the tonal balance that sounds most natural to you. At moderate rotations away from center the effect of the Bass control is subtle, because its action is confined to the lowest audible frequencies where significant energy is seldom found in recordings. Only at large rotations away from center is there a substantial boost or cut at the mid-bass frequencies that are common in music. When the TONE DEFEAT button is engaged, the Bass and treble circuits are bypassed.

9. TAPE 2 INPUT/OUTPUT.
These jacks allow you to connect a second tape recorder of any type, and the preamplifier is wired to permit copying tapes from one recorder to the other. Connect a cable from the TAPE 2 OUT jacks of the 114 to the recorder�s LINE IN jacks, and another cable from the recorder�s LINE OUT jacks to the TAPE 2 IN jacks.

10. PRE OUT 1 & 2.
Two pairs of RCA phono preamp output jacks are provided for convenience. This is the normal output from the preamplifier. Connect a stereo signal cable from these jacks to the main input jacks on your power amplifier. The preamp has a low output impedance (220 ohms). It can drive several amplifiers connected in parallel, and it can be used with long signal cables in order to drive power amplifiers that are located near the speakers (or �powered� speakers having built-in power amplifiers). If you have a special loudspeaker equalizer or another signal processor that should be installed in the signal path after the volume control, connect a cable from either pair of the PRE OUT jacks to the input of the processor, and a second cable from the output of the processor to the main input of your power amplifier.

4. TONE DEFEAT.
When this button is pressed the Bass and Treble circuits are bypassed, restoring precisely flat frequency response. This provides a convenient way to evaluate settings of the Bass and Treble controls. By adjusting the tone controls and then switching them in and out of the signal path, you can easily evaluate their effect on the musical sound.

5. TREBLE.
The Treble control adjusts the relative level of the high frequencies in the sound. The response of the preamplifier is flattest when the control is set in the detent at the 12 o�clock position. Rotation of the Treble control to the right (clockwise) increases the level of high-frequency sounds, and rotation counterclockwise decreases their level. Adjust the Treble control to achieve the tonal balance that sounds most natural to you. Boosting the Treble increases the brilliance and clarity of details in the sound, but also makes any noise more prominent. Turning down the Treble makes the sound mellower while suppressing hiss and record surface noise; but too much Treble roll-off will make the sound dull.

11. AC LINE CORD.
After you complete all connections to the preamplifier, plug the AC line cord into a �live� AC socket.

FRONT PANEL CONTROLS
1. POWER
Press to switch on the power to the 114 (and to any other products plugged into the SWITCHED convenience outlets on the rear panel of 120V versions) . To switch the power off, press the button again.

6. BALANCE.
The Balance control adjusts the relative levels of the left and right channels. It has no effect on recordings being made. A detent at the 12 o�clock position marks the point of equal balance. Rotation of the Balance control to the right (clockwise) decreases the level of the left channel so that only the right channel is heard, thus shifting the sonic image to the right. Rotation of the control to the left shifts the sonic image toward the left speaker.

2. PHONES
Plug stereo headphones in here. The circuit will provide proper drive signals for all conventional stereo headphones regardless of their impedance, with just one exception: electrostatic headphones usually are supplied with an adapter unit which must be connected directly to the speaker terminals on your power amplifier.
