USER’S GUIDE

SCM-660

LARGE DIAPHRAGM MULTI-PATTERN

CONDENSER MICROPHONE

Thank you for choosing Senal.

The Senal SCM-660 is a professional grade, large dual diaphragm, true condenser microphone� Its

dual 1�3˝ gold-plated transducer element is designed to give detailed and true sound reproduction in

professional and project studio applications� Its full rich tone and clarity make it an ideal microphone

for studio recording, broadcasting, podcasting, or live recording� With a wide dynamic range and

high SPL of 140 dB, you’ll be able to capture vocals and instruments accurately with pristine clarity�

The SCM-660’s selectable polar patterns provide ﬂexible options to pick up audio

while minimizing off-axis noise and reﬂections� An onboard -10 dB attenuation pad

allows you to achieve optimal signal levels when in front of loud sound sources such as

guitar cabinets or singing� The 80 Hz high-pass ﬁlter rolls off unwanted low-frequency

noise and rumble caused, for example, by wind or the microphone shaking�

The included shock mount reduces unwanted vibrations when ultimate sensitivity

is required� Rugged all-metal construction provides durability in use or during

transport, and the aluminum case and protective pouch/dustcover add extra

protection� You’ll enjoy using the Senal SCM-660, so let’s get started�

Mounting the Microphone

To mount the SCM-660, follow these steps:

1� Screw the included shock mount onto a 5/8˝ threaded

microphone stand and make sure it is in a 90-degree position�

Then fully tighten the locking knob on the shock mount�

2� Carefully thread the bottom of the microphone to the shock

mount using the shock-mount thread and fully tighten�

Note: The front of the microphone (showing the Senal logo)

should be facing your sound source for recording�

Selectable Polar Pattern Switch

Cardioid

When the cardioid pattern is selected ( ), the microphone will pick up sound from

the front and reject sound from the back of the microphone� This can be used for

most frontal recording applications such as singing or guitar playing�

Figure 8

When in the ﬁgure 8 pattern ( ), the microphone will pick up sound from the front and back of the

microphone� Any noise from the sides will be rejected� This is great for two-person interviews with the

microphone in between them, or MS (mid-side) stereo recording techniques such as drum overheads�

Omni

When in the Omni pattern ( ), the microphone will pick up sound from all

around� This is a preferred setting for high-quality ambience sound miking, or

far-ﬁeld recording in high-quality large and small recording rooms�

High-Pass Filter

The high-pass ﬁlter setting can be used to reduce the sensitivity of the microphone to low-frequency

sounds, additional noise and vibration from outside trafﬁc, air conditioning or other background audio�

When set to ON ( ) the SCM-660 will ﬁlter sound 80 Hz and below� The OFF setting ( ) results in

no ﬁltering�

Attenuation Pad

The SCM-660’s attenuation pad can be used to lower the output by 10 dB for preventing distortion

when recording loud sound sources like singing, percussion, or guitar ampliﬁers� In the left position,

there is 0dB attenuation, in the right position, there is -10dB attenuation�

Connecting the Microphone

Use an XLR cable (not included) to connect the microphone to your mixing console,

microphone preamp, or recording device� Make sure phantom power is turned on�

Note: Phantom power must be used with this microphone� Make sure

your recording device has proper +48 V phantom power�

Warning

Make sure all faders and volume knobs are down� After the microphone is

connected, set the volume to your preferred level for recording�

Before recording, make sure the high-pass ﬁlter is set to OFF ( ) and the

attenuation pad is not engaged� See previous section for further reference�

If using this microphone for vocals, do not sing or blow directly into the

diaphragm� Use a pop ﬁlter (not included) to eliminate vocal plosives and

shield against corrosive moisture that can damage the diaphragm�

Problem Solution

No sound is

being recorded�

Make sure your mixer or ampliﬁer is turned on and phantom power is engaged�

The fader of the channel or master volume on your

mixing console is turned all the way down�

Your preamp gain is turned all the way down�

Make sure the microphone is properly connected and connections are secure�

Check your cable to make sure it’s reliable� Try switching it with another cable�

The sound is

distorted�

Turn on the microphone’s attenuation pad�

Move the microphone away from the sound source�

Too much low-

frequency noise

or rumble is

being recorded�

Turn on the high-pass ﬁlter�

Turn off air conditioners, fans, heaters or other devices

that might be interfering with your recording�
