Sennheiser e 845-S Supercardioid Dynamic Vocal Microphone Instruction Manual

1. Introduction

The Sennheiser e 845-S is a high-output supercardioid dynamic vocal microphone designed for speech, choirs, and close-miked singing. It features an extended high-frequency response and a supercardioid pickup pattern for enhanced signal output and clarity, even in high on-stage sound levels. The microphone maintains consistent sound quality across different proximity levels and offers excellent feedback rejection. Its robust all-metal construction and advanced shock-mounting minimize handling noise and interference, ensuring reliable performance.

Key features include:

• Smooth tonal response with full dynamic range.
• Presence lift for vocal clarity and projection.
• Consistent on/off-axis and proximity response.
• Full metal construction for durability.
• Exceptional feedback rejection.
• Very good rejection of handling noise.
• Hum compensating coil.
• Integrated on/off switch for convenience.

2. Setup

This section guides you through the initial setup of your Sennheiser e 845-S microphone.

2.1 Unpacking

Carefully remove all components from the packaging. The package typically includes:

• Sennheiser e 845-S microphone
• Microphone clip
• Carrying pouch

2.2 Connecting the Microphone

1. Attach the Microphone Clip: Securely fasten the provided microphone clip to a microphone stand.
2. Mount the Microphone: Insert the e 845-S microphone into the microphone clip. Ensure it is firmly seated.
3. Connect the XLR Cable: Connect a standard XLR cable (not included) to the XLR connector at the base of the microphone. Connect the other end of the XLR cable to your mixer, audio interface, or amplifier.

The microphone can be used either on a stand or held in hand, depending on your performance needs.

3. Operating the Microphone

Understanding the characteristics of the e 845-S will help you achieve optimal sound performance.

3.1 On/Off Switch

The e 845-S model includes a convenient on/off switch located on the microphone body. Slide the switch to the "On" position to activate the microphone and to the "Off" position to mute it. This switch is designed to operate silently, preventing unwanted pops or clicks in your audio signal.

3.2 Supercardioid Pickup Pattern

The e 845-S features a supercardioid pickup pattern. This means the microphone is most sensitive to sounds directly in front of it, with significant rejection of sounds from the sides and rear. This characteristic is ideal for isolating your vocal performance from other instruments or ambient stage noise, reducing the likelihood of feedback.

Important Note on Monitor Placement: Due to the supercardioid pattern, the microphone has a small "bunny tail" of sensitivity directly behind it. To prevent feedback, avoid placing monitor speakers directly behind the microphone, facing its rear. Instead, position monitors to the sides or slightly in front of the microphone, outside its primary pickup area.

3.3 Proximity Effect and Frequency Response

The e 845-S offers a consistent on/off-axis and proximity response. This ensures that your sound quality remains stable even if you move closer to or further away from the microphone. Its extended high-frequency response (up to 16 kHz) provides clear and open vocal reproduction, while the presence lift enhances vocal clarity and projection.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your microphone.

• Cleaning: Use a soft, dry cloth to wipe the microphone body. For the grille, a soft brush can remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
• Storage: When not in use, store the microphone in its provided carrying pouch to protect it from dust, moisture, and physical damage.
• Handling: While the e 845-S has a rugged metal body, avoid dropping or subjecting it to excessive force, as this can damage internal components.
• Moisture: Keep the microphone away from liquids. If it gets wet, disconnect it immediately and allow it to dry completely before use.

5. Troubleshooting

If you encounter issues with your e 845-S microphone, refer to the following common troubleshooting steps:

• No Sound Output:
  • Ensure the on/off switch on the microphone is in the "On" position.
  • Check all XLR cable connections at both the microphone and the mixer/interface.
  • Verify that the input channel on your mixer/interface is selected and its gain is appropriately set.
  • Test with a different XLR cable to rule out cable failure.
• Feedback (High-Pitched Squeal):
  • Reposition monitor speakers so they are not directly behind the microphone, facing its rear.
  • Reduce the gain on the microphone input channel.
  • Move the microphone further away from speakers.
  • Ensure the microphone is pointed directly at the sound source (e.g., your mouth) and not towards speakers.
• Low Output Level:
  • Increase the gain on the mixer/interface input channel.
  • Ensure the microphone is positioned close enough to the sound source.
• Distorted Sound:
  • Reduce the input gain on your mixer/interface to prevent clipping.
  • Ensure the microphone is not being overdriven by an excessively loud sound source.
